UPVC Angle Seat Valve

The UPVC Angle seat valves are two by two way pneumatically piston valves actuated. The actuator piston provides a linear motion to lift the seat off its seat. The seat is positioned at an angle, and the flow is impeded minimally in the open position, resulting in an excellent flow rate and a low pressure loss. These are used to regulate the flow of liquids, gases, steam, vacuum, and even aggressive fluids. Also can also operate with high temperatures and high viscosity media, even under zero differential pressures.

The UPVC angle seat valve is a popular choice for harsh applications, and they have a very high life cycle. Therefore, they are an excellent alternative to Ball valves with an actuator combo. These UPVC angle seat valves are also suitable for alternatives to solenoid valves, especially with contamination. They may be operated using a single-acting or double-acting configuration, which has an influence on their pressure rating.
