All That You Should Know About Gas Cylinder Valves


Gases constantly seek ways to escape from or enter into a gas supply system. Cylinder valves are devices that control the flow of the gases into or out of the cylinder. Pertaining to the escaping nature of gases, cylinder valves are gaining importance like never before.

What are the types available?

Packed Valves – These valves are mostly found on acetylene cylinders (B & MC) and corrosive products such as ammonia or chlorine. They typically have a specially designed wrench which has to be removed during shipping & storage.

Pressure-seal Valves – This is a common valve found on most of the cylinders and can be operated using a handwheel at very high pressure levels.

Diaphragm Valves – You can find these valves on cylinders which demand high levels of protection against leakage such as cylinders containing gas mixtures, high purity gases and rare gases such as krypton and xenon.

Post-type Medical Valves – These pin-indexed valves are used in some medical gas products to ensure supply of the right gas to a particular apparatus.

For your convenience and safety, JTC Valves maintains a well-managed inventory of cylinder valves manufactured in the USA by Sherwood and Rego, leading brands in valve manufacturing. All the valves you find here are certified by ASME & ISO 9001 certified.

JTC Valve Sales serves the market with strong, durable and high quality cylinder valves including chlorine valves, medical valves and welding cylinder valves.
