Single Seat Angle Type Control Valve

Single Seat Angle Type Control Valve

Angular Flow Path:Angle-type design improves flow direction and discharge
Precise Flow Control:Single-seat structure enables accurate regulation.
Smooth Operation:Provides stable and responsive control performance.
Reliable Sealing:Ensures tight shut-off when closed.
Clogging Resistance:Suitable for media with particles or high viscosity.
Durable Construction:Designed for long-term reliable operation.

Single Seat Angle Type Control Valve

Single Seat Angle Type Control Valve is a top–guided single seat control valve. It has advantages of small pressure rise loss, large flow, and wide adjustable range. Besides, it has high accuracy of flow characteristic curve.

The valve core adopts pressure balance structure. The control valve is equipped with multi–spring diaphragm actuator or electric actuator, and has compact structure, large output torque.
