The inner hole of the actuator, after being ground through car milling, is smoother, facilitating piston movement and resulting in a longer life cycle
The connection between the valve seat and the valve spindle adopts a floating design structure, which ensures the sealing of the valve disc and the valve port; ;
The S series actuators are suitable for high-pressure and high-temperature operating environments;;
Wide range of piston-type operators (32 - 40 - 50- 63 - 90 - 125- 160 mm dia.) rotatablethrough 360°, for maximum performance at different minimum pilot pressures ;
Anti-waterhammer design (fluid entry under the disc).
