Pneu-Hydro Products Pneu-Hydro Products has long been a le*g manufacturer of pneumatic and hydraulic valves and systems for the aircraft and missile industry. More recently, Pneu-Hydro has also pioneered in the design and fabrication of a rapidly growing line of industrial valves for hydraulic, pneumatic, and specialized fuel applications, especially as applied to automated production equipment and precision machinery of all types. Typical commercial products include co*ol valves, regulators, check valves, relief valves, filters, and actuators. With completely integrated development, engineering, testing, and manufacturing facilities, Pneu-Hydro can meet your most exacting specifications. In many *es existing designs can be applied quickly to your requirements with a speed that rivals off-the-shelf delivery. All our facilities and experience are at your dis*al. Feel free to call on us to discuss your problem. Inline Relief Valves Pneu-Hydro bar stock relief valves remain bubble-tight up to cracking pressure. They reseal at less than 10% drop from cracking pressure in lower ranges, and less than 5% at higher ranges. Cracking pressure is reliable, repeatable and easily set by an internal adjustment, which is *per-proof once the valve is installed in the system. An O-ring seals the poppet while a metallic stop bears the spring load. This simple design provides crisp settings and long life. The standard valve is constructed of 316 stainless steel for strength and durability in the most corrosive applications.

For Viton, insert “V”. Consult factory for other materials. For example, Model No. 401F4Q-2V specifies an inline relief valve with 1/4 NPT female ports, Viton O-rings, and a 250 – 600 psid range. Miniature Relief Valves Pneu-Hydro miniature relief valves provide zero leakage up to cracking pressure. They reseal bubble-tight within 5% to 10% of cracking pressure. Adjustments are insensitive to temperature variations. These miniature relief valves are made from 316 stainless steel for strength and corrosion resistance. Material options can be provided on request. Buna-N or Viton O-rings are standard but other O-ring materials can be provided. Back-pressure on the 405 and 407 series (with connected vent line) should be limited to 1,000 psid.

Consult factory. Optional materials include brass and aluminum. Optional connections include MS-33656-4. Right Angle Relief Valves Pneu-Hydro right angle relief valves are pressure balanced internally and pressure referenced to atmosphere. This yields insensitivity to downstream pressure and permits the valve to be used as a back-pressure regulator. The valve seals against a soft seat and has a metal stop that bears the spring load, prolongs seal life, and prevents sticking. These valves remain bubble-tight up to cracking pressure and reseal bubble-tight at less than 10% drop from cracking pressure (significantly less in the higher pressure ranges). The external setting adjustment is particularly useful in applications where changes are required. The design provides full flow at a very small rise above cracking pressure. Features include a wide series of *ailable pressure ranges, smooth, chatter-free performance, reliable and repeatable cracking and reseating pressures, along with 316 stainless steel construction. Seal material selections are *ailable for compatibility with virtually any fluid chemistry. Standard seal materials are Buna-N and Viton.

When open, they provide a smooth flow-path with minimum resistance. The poppet is spring-loaded for *itive operation regardless of orientation. Back pressure and spring loads are borne by a metal stop rather than the soft O-ring seal. This ensures long seal life and minimum maintenance. Operation is smooth and chatter-free. These check valves are constructed of 316 stainless steel for strength and corrosion resistance and meet the requirements of NACE MRO175. Because of their bar stock design, the valves can be easily made from a variety of materials to satisfy the needs of your operating environment. Buna-N or Viton seals are *ailable from stock, and other O-ring materials can be provided. Specifications Operating pressure ranges Maximum 10,000 psid Operating temperature ranges Buna-N seals -40° to 250°F (-40° to 121°C) Viton seals -20° to 450°F (-29° to 232°C) Ordering Information Inlet Outlet Dimensions Cv Model Number L Hex 1/4 NPT F 1/4 NPT F 2-9/32 3/4 .55 301F4Q 1/4 NPT M 1/4 NPT M 2-11/32 3/4 .55 301M4Q 1/4 NPT M 1/4 NPT F 2-9/32 3/4 .55 301M4F4Q 3/8 NPT F 3/8 NPT F 3-1/8 1-1/16 1.3 301F6Q 1/2 NPT M 1/2 NPT M 3-5/8 1-1/16 1.3 301M8Q Notes: Buna-N seals are standard.

When co*ol pressure is applied, the internal poppet closes the quick-vent port and directs flow through the outlet to the actuator. Upon release of pressure, the poppet’s internal check closes and the poppet is lifted off the vent seat. The large capacity of the outlet/vent passage permits rapid flow from the actuator. The valve is constructed of corrosion resistant materials in accordance with NACE MR-01-75. Specifications Operating pressure ranges Maximum 10,000 psid Operating temperature ranges Buna-N seals -40° to 250°F (-40° to 121°C) Viton seals -20° to 450°F (-29° to 232°C) Ordering Information Part No. Deion 433254 Buna-N seals 433254-V Viton seals Hand Valves Pneu-Hydro hand valves offer design and operating features not typically found on valves of this pressure range. The Teflon stem packing is located below the stem threads and pintle swivel. This helps prevent con*ination and lubrication washout by isolating this critical area from the process fluid. This, combined with the very low operating torque (less than 10 lb-inches), provides a precise “feel” and adjustment sensitivity over the lifetime of the valve. The valve stem is designed so that it cannot be inadvertently backed out of the valve. The low profile makes this valve ideally suited for panel mounted or other limited space applications. Standard features include self-aligning swivel pintles to minimize seat scoring, Teflon stem seal, and 316 stainless steel construction to provide maximum compatibility with corrosive fluids.

The slightest pressure blows this ball from one O-ring seat to the other and directs flow to the outlet port. The breakaway friction of sliding seal designs is eliminated by this “contact seal” principle. Pneu-Hydro shuttle valves are made from 316 stainless steel. Buna-N seals are standard, but Viton or other elastomers are *ailable to meet specific requirements. Specifications Operating pressure ranges Operating pressure 250 psig (maximum) Proof pressure 375 psig Burst pressure 5,000 psig Operating temperature ranges Buna-N seals -40° to 250°F (-40° to 121°C) Viton seals -20° to 450°F (-29° to 232°C) Cv .40 Ordering Information Part No. Deion 801F4Q Buna-N seals 801F4Q-V Viton seals Pneumatic Co*ol Valves Pneu-Hydro’s pneumatic co*ol valves are simple and robust. These smooth acting valves offer bubble-tight sealing. They can be line, panel, or bracket mounted to comply with your toughest installation problems. Constructed of 316 stainless steel, with a broad selection of *ailable O-ring materials, they can be used in your toughest applications.

The pilot section handles pressures to 1,000 psi; the hydraulic section accommodates pressures to 10,000 psi. In this unique spool valve design, the usual pilot diaphragm is replaced by a piston. The use of a stainless steel piston and compatible seal eliminates failures due to diaphragm leakage and incompatibility of diaphragm with process fluids. A high ratio of hydraulic power pressure to pilot co*ol pressure insures safe operation and *itive co*ol under all conditions. A pilot pressure of 50 psi co*ols 5,000 psi hydraulic power; 80 psi pilot pressure co*ols 10,000 psi hydraulic power pressure. A soft seal design insures zero leakage in the hydraulic power section. Metal-to-metal seating insures against leakage in emergency situations. Failsafe closure is insured, as both the internal spring and hydraulic pressure acting on the differential spool area provide sufficient force to effect closure, should one or the other fail. Normally both act to close the valve. A *itive indicator of operation is provided in the spool extension, which shifts to show *ition. Excellent flow capacity is provided with a value of Cv=0.5 or the equivalent of an orifice of .224 inch diameter. A normally open version of this valve is also *ailable under product number 433242-P. With minor differences the dimensions and operating parameters are the same for this version. The manual override version has a turning handle located at top center of piston housing.

Its poppet is normally held open by a spring and flow is permitted in both directions through the valve. In the event of down-stream failure (line-rupture, seal-failure, gauge over-pressurization and failure, etc.) the resultant pressure-drop across the poppet orifice creates an imbalance which closes the poppet. The poppet remains closed, preventing further escape of fluid, until the system is repaired. Removal of supply pressure for system maintenance allows the spring to reset the poppet to its open *ition.

Ordering Information Part No. Deion 213677 Viton seals Sand Probe Valves Continuous monitoring of the effects of an abrasive product on flowline and valves is *sible with the use of the Pneu-Hydro Products sand probe. A sensing probe of a predetermined thickness extends through the pipe wall into the flow path of the abrasive product. When the probe is cut, indicating a known degree of erosion to lines, valves, and fittings, pressure from the flowline enters the sand probe valve body, shifting the spool valve and vents off a co*ol pressure. This signal may be used to either close a valve or trigger an alarm. The device is suitable for use with pneumatic co*ol systems. Select the probe length and thickness from the probe kit chart on this page. The sensing pilot is designed with a 1/2 NPT male thread for attachment to the pipe. This surrounds a 1/4 NPT female connection. With this configuration, probes can be readily fabricated in the field from standard fittings and tubing. Features and Advantages Wide pressure range: This device may be safely operated in flowlines containing pressures in the range of 25 psi to 10,000 psi. Co*ol pressure range: The pilot handles a co*ol system pressure of 20 psi to 250 psi. Visual indicator: When the probe has been cut and the pilot spool shifts, the palm button and red band on the main spool indicate that the pilot has been activated. Manual co*ol: The palm button on the pilot may be used at any time to cycle the valve and test the system. Simplicity: When the probe has been cut by abrasive action of the flowing product, the pressure in the pipeline shifts the pilot spool. Choice of probes: Standard wall probes are *ailable in thicknesses of .028; .035; .049; and .065 inches. Standard length probes are 6, 10, and 14 inches. Selection Procedures The sand probe gives an accurate indication of the erosion on the flowline and its components. In the following procedure, the use of probes of different wall thicknesses is demonstrated: Pipe: 2-inch schedule 80 - normal wall thickness .218-inch. Minimum wall thickness for 1200 psi operation: .15 inch. Maximum allowable erosion: .068 inch (.218 minus .15).

Pressure Indicators Pneu-Hydro’s pressure indicator offers easy to read evidence of the presence or absence of pneumatic pressure in a co*ol circuit. When pressure rises to approximately 14 psi, a solid green band shows through the window. If the pressure drops below 8 psi, a red and white striped band appears. The colors are reflective for visibility in lighted surroundings. The striped section provides added recognition of system status under dimly lit conditions or for color-blind personnel. The unit mounts through a 1-3/4” diameter hole and in panels from 17 gauge to 3/16” thick. The indicator is constructed of 316 stainless steel and satisfies NACE MRO175 standard.
