Pneumatic Valve Positioners NZ

HD Process supplies valve positioners for compatible piston and butterfly valves where proportional valve control is required rather than simple open/closed operation.

Closed-Loop Valve Position Control

• Continuously compares valve stem position with the control signal.
• Adjusts actuator pressure to achieve the required valve position.
• Supports smoother control of process flow, pressure and temperature.
• Improves valve response to changes in the process control signal.
