MillerOverview of Electric Regulating Diaphragm Valve:
The 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 alkali and corrosive media. Used with diaphragm valvePSLComposed of a series of electric actuators. There is a servo system inside the electric actuator, which does not require additional service amplifiers and has input control signals(4-20MAperhaps1-5VDC)It can be controlled by a single-phase power supply to adjust parameters such as pressure, flow rate, temperature, and liquid level.
