Stainless Steel Imperial Needle Valve - 10,000 psi Rated - 1/2" Male x 1/2" Female - NPTF

Stainless Steel Imperial Needle Valve - 10,000 psi Rated - 1/2" Male x 1/2" Female - NPTF

The 'HP' series of needle valves are specially designed & manufactured for use in corrosive & hazardous environments. These valves are for use in process control, instrumentation & flow control applications.

Feature Benefits: One piece body construction for strength & safety. Non rotating Vee tip design, which forms a bearing joint with the stem eliminating any rotation between the plug & seat on closure ensuring long life.

Testing: Each valve is hydrostatically tested in accordance with MSS-SP-99. This procedure include testing of the body cavity. A hydrostatic test is performed with pure water or other liquids of similar or lower viscosity at 1.5 times & seat leakage test at 1.1 times of the maximum working pressure. Each valve is also tested with Nitrogen Gas at 1000psi for seat, seal & shell leakage. Other tests like vibration, temperature and helium are available on request.
