Complete Description

REGO T9452 1/4″ FNPT Short Stem Cryogenic Valve – 600 PSIG – O2 Cleaned

The REGO T9452 is a compact T9450 Series short-stem shut-off/globe valve engineered for cryogenic liquid and gas handling applications. It features 1/4″ FNPT inlet and outlet connections, a rugged brass body and bonnet, PCTFE seat disc, PTFE stem seal gasket, stainless steel spring, and aluminum handwheel.

Its low-profile, non-rising stem configuration makes the T9452 particularly useful where installation space is limited. The spring-loaded stem sealing system automatically compensates for gasket wear, reducing the need for repeated packing adjustments. A pressure-sealed moisture barrier is incorporated to help prevent freeze-up during operation at cryogenic temperatures.

The valve has a 600 PSIG maximum working pressure and an operating temperature range of approximately -320°F to +165°F (-196°C to +74°C). It is cleaned for liquid oxygen service in accordance with CGA G-4.1 and is 100% factory tested.

Applications

The T9450/T9460 family is designed for portable cryogenic cylinders and in-line shut-off applications. The T9452 is also used for cryogenic tank trycock and hose-drain service and for liquid-fill or vent applications on mini-bulk systems.

Typical applications include:

• Portable cryogenic cylinders
• Cryogenic storage tanks
• Mini-bulk systems
• Liquid fill lines
• Vent lines
• Hose drain valves
• Trycock valves
• Cryogenic piping and manifolds
• Industrial gas handling equipment
• Oxygen, nitrogen, argon and other compatible cryogenic gas/liquid systems
