The SGON Straight Through Diaphragm Valves is used to control non corrosive or general corrosive medium. The inner cavity surface of the valve body is unlined or covered with various kinds of rubber, suitable for different working temperature and liquid pipeline. Diaphragm valve is a special type of truncation valve, flexible seal open and closed, to ensure no leakage, streamlined flow channel, so that the pressure loss is small, no packing letter, so there is no leakage, the valve body and cover are separated by the middle diaphragm, so that the valve cover above the diaphragm, the valve stem and other zero parts are not eroded by the medium and the diaphragm can be replaced, The maintenance cost is low, the lining material is diverse, it can be applied to all kinds of media, and has the characteristics of high strength and good corrosion resistance.

The Stainless Steel Diaphragm Valves and conventional valve structure and working principle are different, it is a self force structure, does not need external power supply wind, its work is done through the process medium (compressed air), compressed air through the throttle hole into the stainless steel diaphragm valve chamber.

The SGON Electric Actuator Diaphragm Valves is composed of a valve body, a valve cover, a valve stem, a disc, a diaphragm, an electric device and other driving parts.The opening and closing of the valve is driven by the connecting shaft of the electric device to drive the stem nut, so that when the valve rod moves axially, the valve flap can be driven up and down to achieve. When the power supply breaks down and the valve is in urgent need of opening and closing, the hand - electric handoff handle should be first converted to the manual marked position, and the flash door can be opened and closed through the rotating handwheel. When rotating clockwise, the valve can be turned off; otherwise, it will turn on. When the electric operation is resumed, the switch handle must be switched to the position marked with electric mark, so that the electric operation can be carried out.
