Cylinder valves

Cylinder valves are used in gas cylinders for storing and transporting Nitrogen, Argon, Oxygen, Hydrogen, Carbon Dioxide and various other industrial gases. Various kinds of cylinder valves are available with us depending on their inlet and outlet thread size, working pressure, gas types and operational procedures. These valves are designed as per Indian standards and are approved duly by CCOE and BIS. As per these standards, different types of gases with different nature of gases like toxic, inert or flammable are filled in the cylinder fitted with valve having different types of outlet threads.

Basic material used for manufacturing cylinder valves is brass or steel depending on the nature and type of gas. We provide various types of valves made on high-precision machines using the advanced technology. Each valve is tested for its test pressure at 1.5 times of their working pressure.

These valves are either key operated or wheel operated depending on the requirements. We also offer Minimum Pressure Retaining MPR and Residual Pressure Valves RPV as per requirements of clients. MPR and RPV valves maintain pressure inside the cylinder and do not allow the contents to get empty from the cylinder. This type of arrangement provides a good life to the cylinder and it also prevents moisture or impurities from getting inside.

We provide different valves in different materials as per the nature of corrosive and toxic gases.  We can also supply cylinder valves in different thread sizes as per the Indian Standards and particular needs of clients.
