[Valve features]
The electric control valve has the advantages of simple structure, small resistance, circulation flow path than with other large caliber valve, no leakage, can be used to adjust the high viscosity fluid and suspended particles, according to different membrane materials (rubber or PTFE) suitable for regulating alkali, strong corrosive medium. The electric control valve is composed of a diaphragm valve and a PSL series electric actuator. The electric actuator in the servo system, no additional servo amplifiers, have the input control signal (4-20mA or 1-5VDC) and single-phase power can control the operation, we can adjust the parameters of pressure, flow, temperature, liquid level etc..

[Adaptive condition]
Applicable to high viscous fluid, suspended particles, fibrous media and toxic media, corrosive media adjustment occasions.
