Cylinder Gas Valves

  • A Guide to Industrial Valves - Types & Functions

    Cylinder Valves are typically the most useful component of any industrial equipment or machine. Thus, it is important to understand their functionality and types in detail. Although these are tiny items, valves control the working of most of the machines. The mechanical device blocks a pipe partially or fully to change the amount of liquid or gas that passes through it. This small but critical function of the valves cannot be neglected as a slight more or less amount of substance released from the valve can lead to hazardous disasters.

    Industrial valves regulate the pressure of gas or liquid it releases so that an apt amount is delivered and the best output is delivered. They are often made from plastic or metal and consist of different parts – the stem, the body, bonnet, trim, actuator, and packing. It is essential that all the parts of the valves are strictly adhered to each other at the right places as any defect may lead to serious accidents and even explosions.

    Here are some important valves:

    Check valves: Check Valves are used to allow a proper flow of air, liquids and steam/condense gases. They are flow sensitive and rely on the line fluid to open or close. Some valves like swing check valves allow automatically close when the pressure decreases and closes fully when the flow reaches to zero. These valves prevent the reverse flow in a piping system.

    Gas/Cryo Valves Gas/Cryo Valves : Series LPG Valves

    Gas/Cryo Valves: Specially designed for allowing the flow of cryogenic gases including Oxygen, LNG, and Nitrogen. The cryogenic valves ensure you durability and safety. Sherwood and Rego cryo valves are the best for use. Series LPG valves are popular cryo valves that are used to forklift trucks, engine fuel installations, RVs and over 1000 gallon water capacity tanks.

    Gate Valves: These valves can be opened or closed just by lowering the metal gates across them. However, you will have to completely open or close the valve as they may not function properly while partially open.

    Needle Valves: Needle valves function precisely and are mostly found in car engines, carburetors, and central heating systems.

    Relief Valves: These are tamper resistant valves designed for use with gases not only fluids. The relief valves are used in cryogenic relief containers and vapor line safety relief application.

  • Safe Handling of Acetylene Cylinders To Avoid Potential Hazards

    Acetylene is inherently a safe gas and is an invaluable commodity for the industry. Being a highly flexible gas, acetylene is used in many industrial processes. It is known to an irreplaceable for oxyfuel gas welding and cutting. It features high versatility and functionality with also being hazardous if not handled with care. However, the acetylene cylinders have a different design from most other gas cylinders and the gas reacts differently when exposed to fire.

    acetylene valves

    Safeguarded by acetylene cylinder valves, the acetylene cylinders consist of a steel shell comprising a porous mass which in combination with liquid acetone dissolves the gas. Decomposition of acetylene is triggered by heat, leaving the cylinder in an unstable, hazardous condition and can also lead to explosion.

    Due to the special potential for a delayed action rupture with acetylene cylinders, observing certain safety measures to minimize the risk and level of destruction.

    Tips to handle acetylene gas cylinders:

    • The alarm should be sounded and area evacuated in case of any event of an incident
    • Train the user appropriately before letting him use Oxyfuel gas equipment
    • Fit non-return acetylene valves on the torch
    • Check for any leaks prior to lighting up
    • Prefer to ignite the fuel gas equipment before introducing the oxygen stream with the nozzle pointing upwards
    • During transport, ensure that the vehicle is properly ventilated and there are appropriate restraints to save the gas filled cylinders from exploding
    • After being transported, the acetylene cylinders must be left to settle in an upright position so that the liquid acetone returns to its normal position in the porous mass
    • Always use a flashback arrestor while using acetylene cylinders
    • Never open the acetylene cylinder valves more than one and a half turns as it can be closed easily in case of an emergency

    We, at JTC Valve Sales, understand the strict industry specifications and only sell products which comply with the highest quality standards & undergo a thorough automated testing process. You can place an order for all your valve requirements with us as we stock almost all of them.

  • All That You Should Know About Gas Cylinder Valves

    All That You Should Know About Gas Cylinder Valves

    Cylinder Valves 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 hand-wheel 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.
