Welding high-pressure needle valves for power plants are designed specifically for thermal power generation, nuclear power, and supercritical units
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.
The integrated welded double needle valve is primarily used in gas dispensing devices, serving as an instrument root valve or process valve.
