Application: Pneumatic Control Valve Automation
The Explosion-proof Valve Positioner is designed for pneumatic control valve automation in hazardous industrial areas. It receives the control signal from the control system and adjusts the air output to the pneumatic actuator, helping the valve reach the required opening position accurately.
This AVP8700 explosion-proof valve positioner is suitable for linear stroke and rotary stroke pneumatic actuators, including single-acting and double-acting actuator configurations. It can be used on pneumatic control valves, pneumatic ball valves, pneumatic butterfly valves, and other automated valve packages.
The positioner supports optional HART communication, 4–20mA valve position transmitter output, dual electronic switch output, and pressure gauge assembly options. Explosion-proof versions are available for gas and dust hazardous areas, making it suitable for oil and gas, chemical, power, water treatment, and other process industries.
Explosion-proof Design for Hazardous Areas
The valve positioner is available with explosion-proof configurations for gas and gas/dust hazardous environments, suitable for industrial valve automation in demanding areas.
Suitable for Linear and Rotary Actuators
The positioner can be used with both linear stroke and rotary stroke pneumatic actuators, making it suitable for control valves, ball valves, and butterfly valves.
Single Acting and Double Acting Options
It supports both single-acting and double-acting pneumatic actuator operation, covering common control valve automation requirements.
Optional HART Communication
The HART communication option allows easier commissioning, signal monitoring, and integration with plant control systems.
Optional 4–20mA Position Feedback
The valve position transmitter output option provides a 4–20mA feedback signal for valve position monitoring.
Dual Electronic Switch Output Optional
The optional two-way electronic switch output supports valve open/close position indication and remote status feedback.
Pressure Gauge Assembly Options
Standard pressure gauge assembly and stainless steel pressure gauge assembly options are available for field air pressure monitoring.
Flexible Connection Options
The positioner supports multiple power and air connection combinations, including M20 × 1.5, 1/2 NPT, G1/4, and 1/4 NPT.
