Cryogenic Valves

Fire tested to API 607
ValvTechnologies’ cryogenic valves are built to withstand the most severe applications. This solution represents an important step forward in cryogenic technology by providing absolute zero-leakage thanks to the RiTech® coated integral seat, live-loaded fugitive emissions and fire safe tested design. ValvTechnologies’ metal seated cryogenic valves are available in a variety of materials suited for extremely low temperatures.
Size : 1/4 - 36”
ANSI/ASME Class 150 - 4500


• Through conduit design: No tortuous flow path. When open it has the highest possible Cv’s. Minimized wear & tear. Benefit: Eliminated vibration, reduced maintenance
• Fixed position – quarter turn: No seating torques required. Benefit: Minimized stem wear, lower cost of ownership
• Hardened blowout proof stem: One piece, inserted through the body & shouldered. Eliminates the weak link of collared & pinned designs. Benefit: Improved safety
• Metallic body seal ring: Increases body integrity by eliminating external leakage. Benefit: Improved reliability, zero-leakage shutoff
• Live-loaded packing gland: Minimum four bolt configuration with shallow stuffing box. Ensures consistent torque at variable pressures & temperatures. Benefit: Increased reliability
• Hardcoated & mate lapped seats: High Velocity Oxygen Fuel (HVOF) RiTech® chrome carbide hardcoating with a Rockwell C of up to 72. Mate-lapped seats. Benefit: Wear & corrosion resistant, increased reliability, zero-leakage shutoff
• Seat designs: Hardcoated, both ball & integral downstream seat to the end-cap to eliminate a potential leak path. Benefit: Increased reliability
• Simplicity of design: Designed for ease of installation & maintenance. Benefit: Easily actuated, increased system reliability, increased efficiencies, ease of use, reduced maintenance
• Stringent testing: Every valve is tested, documented & serialized. Benefit: Increased reliability, increased safety, total traceability
