So what are the characteristics of the electric diaphragm control valve?
1. Overview of imported electric diaphragm regulating valve
INGRAM imported electric diaphragm regulating valve adopts diaphragm valve as the valve body. It has a simple structure, small flow resistance, greater flow force than other valves of the same caliber, no leakage, and can be used for high viscosity and suspended particles. Fluid regulation. It is suitable for adjusting strong alkali and strong corrosive medium according to different diaphragm materials. The imported electric diaphragm regulating valve is composed of a diaphragm valve equipped with various straight-stroke electric actuators. The electric actuator used in the electric diaphragm regulating valve has a servo system, without the need to be equipped with an amplifier, and can control the operation with input control signals (4-20mA or 1-5VDC) and single-phase power supply to achieve pressure, flow and temperature , Liquid level and other parameters adjustment.
