High Pressure Equipment Medium Pressure Valves, Fittings and Tubing 20,000 psi service High Pressure Equipment Company has developed a line of Medium Pressure products to assure safe and easy plumbing through 20,000 psi. These needle valves, fittings, line filters, check valves, safety heads, rupture discs, anti-vibration gland assemblies, tubing and nipples are engineered to the highest standards of repeatable quality. The reliable performance of these products has made HiP one of the world’s leading suppliers of elevated pressure components. Medium Pressure components use a compact coned-and-threaded connection which permits the larger bore sizes and increased flow rates common in this pressure class. Medium Pressure valves are available in 1 /4", 3/8", 9/16", 3/4", 1" and 11/2" O.D. tubing sizes and six patterns to satisfy widely varied requirements. A line of fittings is available to facilitate adapting to Taper Seal, High Pressure or other threaded pipe systems.

High Pressure Equipment Medium Pressure (coned & threaded) type connections for 1/4", 3/8", 9/16", 3/4", 1" and 11/2" O.D. tubing. Non-rotating slotted stems are standard on LF4, LF6 and LF9 for on-off service and ensure long life on valve seats. Regulating tip stems are available for all valves at no additional cost, add REG to part number. Glands and collars for tubing are supplied with each valve unless otherwise requested (glands and collars shown on pages 32 and 39). Materials include high tensile type 316 stainless steel bodies and hardened 17-4PH stainless steel lower section stems....

High Pressure Equipment Valve Options Extreme Temperature Valves The Extreme Temperature Extension provides a means to move the packing area (stuffing box) away from the hot or cold zone of a valve. Fins are provided around the packing area to dissipate heat or cold with this option. Size range. Extreme temperature extensions are available for all medium pressure valves. Materials and features. Standard packing is Grafoil and Teflon. Nonrotating tip stems prevent galling at the seats and minimize torque requirements for positive shut off. When ordering, simply add the suffix “-HT” or “LT”...

High Pressure Equipment Union Couplings (Slip Type) Union (slip type) couplings are ideal for use in confined space installations. This design allows the entire coupling to be disconnected and slipped back over the tubing to facilitate assembly and disassembly. In installations where tubing is easily assembled, it is preferable (and less expensive) to use standard straight couplings (see section 12). Standard material is high tensile 316 stainless steel. Standard tubing collars and glands are provided unless otherwise specified. Bulkhead Couplings Bulkhead couplings are designed...

Medium Pressure Valves Line Filters The line filters as shown utilize sintered stainless steel filter discs 4 pc./set. Porosities are available as per the chart to the right. If not otherwise specified, 100 micron filter discs are supplied. (One micron = 0.001 millimeters). Material of body, caps and cover is high tensile 316 stainless steel. Standard tubing glands and collars are provided unless otherwise specified. Ball Check Valves Ball type check valves insure flow in one direction only. Material for body, caps and cover is high tensile 316 stainless steel. Standard tubing glands and...

High Pressure Equipment Safety Heads The male inlet design can be inserted directly into the tubing connections of valves and various fittings such as tees and crosses, or located in pressure vessels. Outlet connections are 3/8" pipe (NPT). This outlet may be connected to a suitable discharge line to vent pressure to a safe location in the event of bursting of the rupture disc. Torque required for sealing rupture discs will range from 40 to 90 foot pounds, depending upon pressure and media being used. Material of body and hold down nut is high tensile 316 stainless steel. Standard tubing...

Medium Pressure Valves Rupture Discs 1" /4 Angled Seat SPECIAL DISCS are available on special order for pressure ranges not shown below and in numerous materials and coatings. Consult factory for price and delivery. Standard rupture discs are available from stock in burst pressures as listed in the chart below. All pressures through 20,000 psi are shaded. These discs are 316 stainless steel (except for 1,000 psi which are inconel) and may be used with any of the safety heads shown. Note that these rupture discs are supplied with a range of plus 6% and minus 3% of specified burst pressure....
