VALVES
CV5600 Series
Check Valves

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 air from entering the pigtail and manifold when a cylinder is removed.

These check valves are bubble-tight against any back pressure.

Note: Check valves are also available housed within a CGA connection.
