Pneumatic Single Acting Spring Return Forged A105 Flanged RF Trunnion Ball Valve
Product Features
Pneumatic actuator: Equipped with a single-acting pneumatic actuator, which drives the opening and closing actions of the valve through the air source. The spring return function can automatically switch the valve to the safe position when the air source is interrupted or fails, ensuring the safety of the system.
Forged valve body: Made of forged A105 material, it has high strength, high toughness and good corrosion resistance, can withstand relatively high working pressures and temperatures, and is suitable for a variety of harsh working conditions.
Full bore design: It provides a full bore flow path, reduces flow resistance, improves the efficiency of medium flow, reduces energy consumption, and is especially suitable for the transportation of large-flow media.
Reliable sealing performance: The valve seat adopts soft sealing materials, such as polytetrafluoroethylene (PTFE), etc., which closely cooperates with the ball to achieve bidirectional sealing, ensuring that the valve can maintain good sealing performance under various working conditions and prevent medium leakage.
Fire safety design: It complies with fire safety standards such as API 607. Even in extreme situations such as fires, after the elastic seals of the valve are burned out, it can still rely on the metal-to-metal sealing structure to maintain the sealing performance and prevent the spread of fires.
Anti-static design: By installing springs between the valve body, the ball and the valve stem, the charge continuity among metal parts is ensured, electrostatic accumulation is prevented, and the risks of fire and explosion are reduced.
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: In addition to pneumatic operation, it can also be equipped with other operation modes such as manual and electric operation to meet the needs of different working conditions and users.
