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.
Ball head welded needle valve bodies are mostly made of integral forged stainless steel or alloy steel, with a pressure resistance of PN420 or above
Specially designed for high-voltage testing and control systems, with a pressure rating of 20000-60000 psi (138-414MPa).
Stainless steel internal thread high-pressure needle valve adopts 304 or 316, 316L stainless steel integral forging valve body, with strong corrosion resistance
