A BW globe valve controls flow by moving a disc against the valve seat, featuring butt weld ends for strong, leak-proof pipe connections. Ideal for high-pressure, high-temperature applications, it is widely used in oil, gas, chemical, and power industries for reliable flow regulation.
Valve body: usually made of cast steel, stainless steel and other materials, resistant to high pressure and corrosion.
Valve disc (valve disk): made of stainless steel or carbon steel, surface hardened, wear-resistant.
Valve seat: cooperates with the valve disc to ensure sealing, made of stainless steel or polytetrafluoroethylene (PTFE).
Valve stem: made of stainless steel, corrosion-resistant and high-strength.
Handwheel or actuator: manually operated or equipped with electric or pneumatic actuator.
Stuffing box: used to seal the valve stem to prevent medium leakage.
Oil and gas: used for high-pressure pipeline transportation and storage.
Chemical industry: suitable for corrosive media.
Electricity: used for boilers and cooling systems.
Nuclear power: used for high-temperature and high-pressure media.
Water treatment: used for water supply and sewage treatment.
