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
