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 valve body is made of integral forged stainless steel or alloy steel, with a pressure resistance of PN100-PN420; Built in precision conical needle valve core, achieving precise adjustment and reliable shut-off of micro flow, widely used in pressure gauges, transmitter pressure pipelines, and high-pressure, high-temperature, or high-purity medium systems that require frequent maintenance, while ensuring sealing and improving installation flexibility.
Welding high-pressure needle valves for power plants are designed specifically for thermal power generation, nuclear power, and supercritical units
The Y-shaped high-pressure needle valve adopts a Y-shaped flow channel structure, effectively reducing flow resistance and improving flow capacity
Used for high temperature, high pressure or extremely dangerous medium systems to eliminate the risk of leakage. The 90 ° angle flow channel design is easy to install and drain, and the precision conical needle valve core is equipped with a hard alloy seal to achieve precise adjustment of micro flow and zero leakage shut-off.
