Hydrogen Soft Seat Needle Valves

Material of construction: 316 SS, PEEK, PTFE
Temperature Range: -58°F to +392°F (-50°C to +200°C)
Aluminum actuator (Air to Open)
Available as 2-way straight and 2-way angle
ATEX Approved

Traditional metal-to-metal seated needle valves often fall short when it comes to achieving a leak-tight seal with gases. BuTech’s new Soft Seat Needle Valve (Patent Pending) combines the trusted performance of a traditional needle valve, with Chevron packing and a soft seat, delivering a true leak tight seal when closed.

Reliable containment for hydrogen and other gases
Tested to ISO standards
Ideal for Hydrogen refueling stations and compression systems, H2 generation, storage, and transfer, R&D lab gas distribution, test stands, tube trailer filling and general system shut off valves for most gases: Nitrogen, Hydrogen, Helium, Argon.
