Check And Relief Valves By Praxair India Pvt Ltd

We are one step ahead from our competitors indulged in manufacturing and supplying huge range of Check and Relief Valves from Chennai, Tamil Nadu, India. Check valves ensure that gases or liquids flow in one direction only. When used on the outlet line of pressure regulators, they prevent back flow of fluids into the regulator. When used in cylinder pigtails, they prevent gas flow from one cylinder into another on the same manifold. They also stop atmospheric air from entering the pigtail and manifold when a cylinder is removed. These check valves are bubble-tight against any back pressure.

Relief valves are commonly used downstream of pressure regulators to protect the regulator, pressure gauge and downstream system from over-pressurization caused by a regulator failure. When properly installed, they may be used with hazardous gases because they have 1/4" NPT outlets that permit vented gas to be piped to a safe disposal system.
