The gas cylinder valve is the safety and control point between the cylinder and the user: the choice of the right valve is crucial for safe use, clean gas and long cylinder life. PWENT offers a complete range of industrial and fire protection valves, in compliance with all EU standards (EN ISO 10297, EN ISO 13340, PED 2014/68/EU).

Valve types by material
Copper valve: the most common and cost-effective choice for standard industrial and mix gases up to 200 bar. Chrome-plated valve: for more chemically aggressive gases (CO2, gas mixtures), with extended life. Stainless steel valve: for special gases, food and pharmaceutical applications where cleanliness is paramount.

Functional types
RPV (Residual Pressure Valve): prevents the cylinder from being completely drained, so no contamination can enter - mandatory for medical and food applications. Pressure relief valve: pressure relief safety function - automatically released in case of overpressure. Standard ball and needle valve for industrial mix gases.

By pressure and gas type
200 bar: for standard industrial gases. 300 bar: for high-pressure applications (H2, compressed process gases). Available gases have specific valve designs: O2 (oxygen - special oil-free), N2 (nitrogen), H2 (hydrogen - special substances), CO2 (carbon dioxide), Ar (argon), gas mixtures (process mixes).

Our staff will help you choose the right valve based on gas type, operating pressure and application. Quantity discount, fast delivery time.
