VA-7200 analog driver

The actuator adopts die-casting aluminum support and cast aluminum shell;

Flexible combination of valve body and actuator can meet the needs of different differential pressure;

Low power consumption, low noise and large output torque;

Forward and reverse control: the forward and reverse can be flexibly wired according to needs to match different valve bodies;

The actuator is a reversible motor with overload protection function. It can produce stable torque at standstill, so that the valve can be stationary at any position;

The spring snap is connected to the valve body, which is convenient for disassembly and assembly.

Application object

Vb-7x00 series electric regulating valve body can be connected with A-7 × 00 series driver is used together. Through the accurate adjustment and control of the valve body, the medium flow in the system pipeline can be adjusted, so as to achieve the control purpose of system constant temperature, constant pressure, constant humidity and other parameters. It is widely used in air conditioning, heating and other building automatic control systems.
