ZDSG type electric diaphragm regulating valve

Product features:

The ZDSG type straight stroke electric regulating diaphragm valve has a simple structure, low flow path resistance, larger flow force than other valves of the same diameter, no leakage, and can be used for regulating high viscosity and suspended particle fluids. Depending on the diaphragm material (rubber or polytetrafluoroethylene), it is suitable for regulating strong alkaline and highly corrosive media. Composed of a diaphragm valve paired with a PSL series electric actuator. The electric actuator has a servo system inside, which does not require an additional amplifier. It can be controlled by an input control signal (4-20mA or 1-5VDC) and a single-phase power supply to adjust parameters such as pressure, flow rate, temperature, and liquid level.
