ANSI 3 Piece Flange Type Cast Steel Rcduce Bore Trunnion Ball Valve
Product Features
Three-piece structure: The valve body adopts a three-piece design, which is convenient for the maintenance and replacement of internal parts and reduces downtime.
Reduced bore: The valve adopts a reduced bore design, which is suitable for working conditions that require precise flow control.
Cast steel material: The valve body is made of ASTM A216 WCB cast steel material, which has high strength and good corrosion resistance.
Flange connection: The flange connection method conforming to the ANSI B16.5 standard is adopted to ensure the firmness and sealing of the connection.
Tripod structure: It adopts a tripod structure to ensure the stability of the ball under high-pressure working conditions and reduce the operating torque.
Fireproof design: It complies with the API 607 fireproof standard to ensure that the sealing performance can still be maintained in extreme situations such as fires.
Anti-static design: Springs are installed between the valve body, the ball and the valve stem to prevent electrostatic accumulation and reduce the risks of fire and explosion.
Emergency sealing injection device: The emergency sealing injection device is equipped in the valve seat and valve stem sealing areas. When the seals are leaked due to wear or damage, the sealing performance can be temporarily restored by injecting sealant, which extends the service life of the valve and reduces maintenance costs.
Multiple operation modes: It can be equipped with manual, gear transmission, electric or pneumatic actuators to meet the needs of different working conditions.
