Product Features

Top-Guide Single-Seated Control Valve seat adopts pressure cage structure, which has the characteristics ofstrong reliability and convenient replacement and maintenance in the later stage.and solves the problem that the traditional structure without valve seat cannot bereplaced due to leakage. The service life can be extended. With fow opening design.the medium tends to the direction of valve opening, with good controllability ofsmall opening and small fow characteristic distortion. According to the workingconditions, electric or pneumatic actuators can be selected for control.
