Our Cylinder Valves

We design and manufacture cylinder valves for a wide variety of applications. These applications require different operating devices, design of the operating mechanism, materials of construction, flow, and pressure rating. Products are classified under each application as per valve series representing a range of valves that share common statutory approval, design standard, materials, and performance characteristics.

Design Testing of Cylinder Valves

Compressed gases shipped in cylinders vary in their chemical composition and properties. Some are oxidizers, some are flammables, some are inerts etc. Gases vary in degrees of corrosivity, toxicity, and pressure and exist not only in the pure state but also in a variety of mixtures. It is a primary requirement of the cylinder valve that it must be suitable for its intended use for public safety.
