The electric regulating diaphragm valve is composed of Z series, LF series direct travel electric actuator and diaphragm valve. The electric actuator is an electronic integrated structure, with servo amplifier, input control signal (4-20mADC or 1-5DC) and power supply to control the valve opening to achieve the adjustment of pressure, flow, liquid level temperature and other working parameters. performance are obviously improved. 

The diaphragm valve body has smooth flow, the throttling element is an elastic diaphragm valve, and there is no packing box on the valve cover. Therefore, the flow capacity is larger than the general control valve and has no leakage, and can be used as a cut-off valve within the range of allowable pressure difference. The valve is suitable for the adjustment of high viscos fluid, suspended particles, fiber media, toxic media and corrosive media. Diaphragm valve is a special form of valve with truncation function, and its opening and closing parts are composed of a diaphragm made of steel valve disc and soft material (rubber and fluorine plastic composite), and the valve body cavity and the valve cover cavity are separated to achieve the purpose of truncating the medium in the tube.
