High pressure gauge needle valves are specifically designed for front-end isolation and protection of measuring instruments such as pressure gauges and transmitters
The high-pressure gauge needle valve is designed for front-end isolation and protection of measuring instruments such as pressure gauges and transmitters. It adopts an integral forging structure and has a pressure resistance level of PN100-PN420; Usually used for internal thread (NPT/G) or socket welding connections, with convenient installation and reliable sealing; Built in precision conical needle valve core, which can fine tune the medium flow rate and achieve rapid cut-off, effectively preventing pressure shock from damaging the instrument. It is widely used in harsh working conditions such as petrochemical, power, hydraulic and high-pressure gas systems.
The panel mounted ultra-high pressure needle valve is designed for compact space and centralized control, integrated into the instrument panel or test bench, with a pressure resistance of up to 20000psi (about 138MPa).
Welding high-pressure needle valves for power plants are designed specifically for thermal power generation, nuclear power, and supercritical units
Ultra high pressure and low-temperature needle valve designed for dual working conditions of deep cold and high pressure
