Extreme Temperature Valves
Proven designs for the challenges of moving specialty gases
Gases like nitrogen, argon, and hydrogen present unique challenges that demand special gas handling components. For more than 60 years HiP has produced standard and custom valves and fittings specifically designed for cryogenic and extreme heat environments. Whether it's for a compressed gas fill plant, a cryogenic test bench or any other gas handling application involving extreme temperatures and pressures, count on proven HiP valves to move your gas.
- Manual and air operated valves for pressures from 10,000 to 30,000 psi
- Extended stuffing box designs move packing away from cold or hot zones for safe and reliable operation
- Special materials such as Monel and Hastelloy available
- Coned-and-threaded connections provide extra dependability
Extreme Temperature Extension
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 1/4" O.D., 3/8" O.D., 9/16" O.D., 3/4" O.D. and 1" O.D. tubing size valves in the 30,000 psi, 60,000 psi series and for all Medium Pressure series 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" to the standard valve catalog number (example: 30-11HF4-HT).
Temperature range of valves with this option is "-LT" -423°F (-252°C) to "-HT" 1200°F (649°C)
