OVERVIEW

Fong’s Electro-Pneumatic Positioner is designed to accurately control the position of actuators and valves in various industrial applications. By converting an electrical control signal into a proportional pneumatic output, it ensures precise control over processes such as flow, pressure, and temperature

SPECIFICATION

• Input Signal: 4-20 mA (standard); optional 1-5 V DC, 0-10 V DC
• Output Signal: Pneumatic signal to actuator (3-15 psi standard)
• Supply Pressure: 20-100 psi (1.4-7 bar)
• Stroke: 10-150 mm for linear actuators; 0-90° for rotary actuators
• Ambient Temperature: -20°C to +70°C (-4°F to +158°F)
• Air Consumption: 6 LPM (0.2 SCFM) at 1.4 bar (20 psi)
• Material: Aluminum housing with epoxy coating or stainless steel
• Protection Class: IP66, explosion-proof options available (Ex ia IIC T6)
• Weight: Approximately 3 kg

FEATURES

• High Accuracy and Sensitivity: Ensures precise control with minimal hysteresis and dead band.
• Auto Calibration: Simplifies setup and calibration processes, reducing installation time.
• Fail-Safe Operation: In the event of signal loss or failure, the positioner moves to a pre-set fail-safe position.
• Feedback Signal: Provides 4-20 mA feedback signal for monitoring the valve position.
• Split Range Control: Allows the positioner to operate in split range mode for specific applications.
• Low Air Consumption: Reduces operating costs and improves efficiency.
• Vibration Resistant: Robust design to withstand industrial environments with high levels of vibration.
• Compatibility: Suitable for both linear and rotary actuators.
