Electric diaphragm regulating valve
Model and specification ZDSG type nominal diameter 15-100mm pressure range 1.0MPa suitable for corrosive media such as strong acids and alkalis
Product details
main 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. This electric regulating valve is equipped with a diaphragm valve and PSL series
Composed of electric actuators. 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.
