Maintenance-free Electric Single-seat Adjusting Valve

Maintenance-free Electric Single-seat Adjusting Valve

The pneumatic diaphragm regulator consists of a multi-spring actuator and a diaphragm regulator. Body shape and weight are lighter than ordinary ones. Small flow resistance, no stuffing box, no leakage, fire, explosion-proof, safe and reliable. The flow path of the diaphragm valve body is smooth, the throttling element is an elastic diaphragm, and the bonnet has no stuffing box, so the flow capacity is larger than the general regulating valve and the sealing performance is good. In the allowable pressure difference can be used as a shut-off valve. Air-opening and air-passing are implemented by positive and negative implementing agencies. Different liners and separators can be used according to different media to obtain better cutting and corrosion resistance. It is suitable for the regulation and control of strong corrosive media such as strong acids and alkalis, high-viscosity fiber and harmful toxic media.globe valve, angle globe valve, straight valve, lifting check valve, swing check valve, 

Chlorine and liquid chlorine control valves are suitable for the piping of various sulfuric acid, hydrochloric acid, aqua regia, hydrofluoric acid, chlorine, liquid chlorine from -50°C to 150°C

Design Feature:

1.Innovative packing design, good sealing performance, small friction, reducing maintenance strength.

2.Special top structure design avoids friction and death between the valve cage and the valve core, stable and reliable.

3.Axial pressure fixation of the valve shaft, good concentricity, very sticky,tight closure,zero-leakage.

4.Standardized components design, interchangeability, easy combined installation, reducing the cost of use.
