Pipe valves may be used both with gases and liquids.

Pipe valves with metal to metal seats have a high level of safety and reliability under adverse operating conditions. These valves may be used both with gases and liquids. Traceability is ensured through extensively documented data (batch number, maximum pressure, material number, type designation). All pipe valves come with female national pipe threads. These are high pressure pipe fittings for high pressures.
These check valves are not to be used as a relief device. The opening pressure of the pipe ball check valves is approximately 10 psi. Connection type on these is high pressure NPT fittings and connections.
