Details
The HEP electric valve positioner can change the electrical signal output by the regulating device into a gas signal to drive the regulating valve, and has the function of valve positioning, that is, to overcome the friction force of the valve stem and offset the balance force caused by the pressure change of the regulated medium, so that Make the opening of the valve correspond to the control signal output by the regulating device to achieve correct positioning.
