ZSH Shanghai Valve Manufzcturing Co.,LTD.

ZRSF (H) type three electric control valve is composed of 3810L series electric actuators and electric actuators in a three-way valve, servo system, without the servo amplifier, electronic control unit is designed to be a box form, and resin casting, driving feedback detection using high performance conductive plastic potentiometer that is the high reliability products with 1/250 resolution, the connection is very simple, only with DC4~20mA or DC1~5V to the input signal and the 220AC single-phase power control operation, the valve has a confluence with the split two ways, can replace the two two valve and a three-way valve and nozzle is widely used in some occasions.
