ZXQ98 Series External Valve Controller - External Valve Positioner

Product Description

The models are as follows:
ZXQ98-9696 (Opening: 92X92) Square
ZXQ98-9648 (opening: 92X45) horizontal type
ZXQ98-4896 (opening: 45X92) vertical type
This positioner can accept the regulating signal of DC 4-20mA from the upper instrument and the "three wire" signal of the potentiometer of the lower electric actuator (or the valve position feedback signal of DC 4-20mA), and output the "on" and "off" signals to control and regulate the valve opening. It can be used with actuators of single-phase AC motors (such as valve angle actuators and straight stroke electric actuators), and can also be used with actuators and electric devices of three-phase AC motors.
1. Display range: 0.0-100.0%;
