Valve Positioner


HVP10 smaller intelligent valve positioned

HVP10 is one smaller intelligent valve positioned. It has the characteristics of small size, light weight and high anti-interferance .etc.. Its principle is the same as the theory of HVP11/12 series that intelligent valve positioner and pneumatic actuator construct a feedback control loop, in this return circuit, the valve position feedback signal is regarded as a variable comparing with given signal in microprocessor and the deviation between them sends out different length of pulse through the outlet of the main control panel to control the output pressure of the I/P conversion unit, thereby the control valve is driven to act.
