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.

Know All About Valves To Get The Most From Your Valves

Industrial valve manufacturers conduct continues research to develop innovative products that are of high quality, durable and can be manufactured at lower costs. As the quality and price of the valve changes, the complete cylinder industry is affected.

Industrial valves include Chlorine valves, medical cylinder valves and welding cylinder valves. The valves are usually operated by hand though innovation and technology has led to valves being of the automatic type that are operated by computerized control systems.

A few commonly asked questions have been answered here for your convenience. We are attempting to give you information on valves. In case you do have some queries, do feel free to write to us and our experts will get back to you.

Q) which is the best valve for oxygen service?

The slow opening needle valve is best suited for O2 service. Ball valves should not be used as they may pose a potential hazard by creating circumstances that are right for ignition.

Q) What kind of valve can be used for vacuum applications?

Diaphragm valves are best suited for vacuum applications due to their diaphragm and metal seal design.

Q) Should ball valves be used for throttling functions?

No. Absolutely not, as throttling causes premature wear of the side discs and packing.

Q) Is there a difference between Cv and orifice size?

Cv stands for U.S gallons flow of water per minute at 21 Deg C with a pressure drop of 1 psi across the valve.  Orifice size is the actual measurement of the size of the flow path.

Q) JTC valve sales stocks valves manufactured by?

JTC valves sales stocks all American made valves that are manufactured by Rego and Sherwood who are leading valve manufacturers.

Q) how to handle cylinders and containers when being moved?

Damage to valve or ruptured cylinder is hazardous. The handler must:

• Wear gloves to protect against pinch injuries
• Safety glasses must be worn to protect the eyes from injuries related to pressure release
• Metatarsal support safety shoes are a must to protect against foot injuries

Q) what are the safe practices for moving cylinders?

• Shut the outlet valve completely
• Valve protection caps should be secured tightly in place
• Use carts or hand trucks to move the cylinders
• Do not allow the cylinders to bang or strike violently against each other
• Do not lift cylinders by the cap or lifting magnet
• Store the cylinders as per the NFPA codes

Q) How to test the cylinder valve for leaks?

The leak test method is used to check cylinder valves for leaks.
