HEP

Electric valve locator HEP series is a kind of the controller output 4-20 ma current signal convert into pressure valve actuators, to overcome the friction of the valve and adjust the medium pressure changes caused by imbalance, make precise positioning, stable valve device.


Features:

The electromagnetic component adopts the new moving coil structure, which is reliable, stable and linear

The range and zero adjustment are handwheel, easy to adjust and lock device

The design of the combined pressure reducer facilitates installation and debugging

High reliability, small volume, light weight
