E/P4000 electric pneumatic valve positioner
Product details
Structural characteristics and application scope
The E/P4000 electric pneumatic valve positioner is used in conjunction with various pneumatic control valves, which can convert DC current signals into pneumatic signals to drive the control valves and control their actions. At the same time, the displacement of the regulating valve is fed back to the locator through a feedback mechanism, forming a closed-loop control. By overcoming the frictional force of the valve stem and the unbalanced force of the valve core, the regulating valve is ultimately positioned correctly according to the input DC current signal. It can be widely used in industrial sectors such as chemical, petroleum, metallurgy, and power stations to control spring return type (single acting) actuators and double acting actuators.
