Exceeds industry standard of 15,000 psi. 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 (FNPT). These are high pressure NPT fittings for pressures up to 15,200 psi.
