The pneumatic O-type insulation regulating (cut-off) ball valve consists of a pneumatic piston actuator and a sandwich integral cast valve body, with a global cylindrical through-hole ball valve core. The valve seat of this product is designed to have a spring like rebound effect to form a bi-directional flexible valve seat, ensuring the reliability of the ball valve seal. It can be widely used in fluids that are prone to crystallization and viscosity, and can meet various occasions that require insulation media. Controlled media such as petroleum with a high content of wax and asphalt are used to prevent crystallization of the media and ensure efficient operation of the self-control system.
