Introduction to imported electric diaphragm regulating valve products:
Electric diaphragm control valve, imported by de lock, Germany, adopts diaphragm valve as valve body, which has simple structure, small flow resistance, larger flow force than other valves of the same caliber, no leakage in sealing, and can be used for the regulation of high viscosity and suspended particle fluid. According to the different diaphragm materials (rubber or polytetrafluoroethylene), it is suitable for the regulation of strong alkali and corrosive medium. The inlet electric diaphragm regulating valve is composed of diaphragm valve equipped with various kinds of direct stroke electric actuators. The electric actuator equipped with the electric diaphragm regulating valve has a servo system, which can control the operation without additional amplifier. It can control the operation with input control signal (4-20mA or 1-5vdc) and single-phase power supply, so as to realize the adjustment of pressure, flow, temperature, liquid level and other parameters.
