VST

Cryogenic ball, gate, and globe valves — engineered for LOX, LH₂, LNG, and the extreme cold-temperature applications that demand specialized materials and proven design.

About the Manufacturer

Cryogenic Specialists. Mission-Critical Reliability.

VST (Valve Solutions and Technology) specializes in cryogenic valves for the most demanding low-temperature applications. From liquid oxygen at -297°F (-183°C) for aerospace propellant handling to liquid hydrogen at -423°F (-253°C) for rocket propellant systems, VST's ball, gate, and globe designs deliver tested reliability in services where standard valves crack, leak, or freeze shut.

What sets VST apart is specialized materials engineering for cryogenic service combined with extended-bonnet designs that keep stem packing out of the cold zone. Stainless and specialty alloy bodies, oxygen-clean preparation, and testing to MSS-SP-134 and beyond. Sizes from 1/2" through 24"+ in ANSI 150 to 1500 ratings.

"Materials, geometry, cleanliness — three things you can't compromise on at -297°F."

Miller Valve has partnered with VST to serve customers in aerospace and defense (where Miller earned a top-tier aerospace quality score), LNG terminals, gas processing, and chemical cryogenics. Oxygen-clean documentation, MSS-SP-134 testing, and full traceability for the mission-critical programs your QA team requires.
