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 high-temperature and high-pressure socket welding needle valve is made of integral forged heat-resistant alloy steel or stainless steel
The double ends of the needle valve with flexible joints are equipped with flexible joints for easy on-site disassembly and maintenance of instruments;
The high-pressure butt-welding double needle valve is integrally forged from high-quality alloy steel or stainless steel, boasting excellent high-pressure resistance.
