Electric thin film regulating valve

Product Name:Electric thin film regulating valve

Product model: ZAZM
Product Description: In addition to the general characteristics of a compact sleeve valve, an electric large-diameter regulating valve also has greater flow capacity and higher operating performance. Therefore, it is particularly suitable for production process control systems for general fluid media and high flow process conditions in industrial sectors such as chemical, petroleum, metallurgy, and power plants. This valve consists of an electric (electronic) actuator and a large-diameter sleeve valve. It has a compact structure, smooth flow channels, precise flow characteristics, wide adjustable range, and minimal valve seat leakage

It is in the automatic control valveThe product not only functions as a switch, but also as a regulating electric valve for valve position adjustment. The stroke of electric actuators can be divided into two types: 90 ° angular stroke and linear stroke, and special requirements can also meet the full stroke of 180 °, 270 °, and 360 °. By using an electric actuator with angular travel and a valve with angular travel, the valve can be rotated within 90 degrees to control the flow of fluid in the pipeline; A straight stroke electric actuator is used in conjunction with a straight stroke valve to control the flow of fluid in the pipeline through the up and down movement of the valve plate.

Electric thin film regulating valveThe regulation principle is: using compressed air as power, controlling the pressure of the air source through an electrical valve positioner, so that the air acts on the rubber diaphragm of the regulating valve. The contraction and expansion of the diaphragm then drives the valve stem to move up and down, thereby achieving the purpose of controlling the medium.

The regulator (DCS signal) converts electrical signals into gas signals through an electrical valve positioner and applies them to the diaphragm of the regulating valve. The diaphragm compression spring drives the valve core of the regulating valve to control the valve opening, thereby achieving the regulation of the regulated medium. According to the process requirements, regulating valves are divided into gas open valves (fault closed) and gas closed valves (fault open).
