Worcester Controls PM15EG Electro Pneumatic Positioner

The Worcester Controls PM15EG Electro Pneumatic Positioner is an industrial valve positioner that converts a 4–20 mA input signal into precise pneumatic actuator positioning for Worcester Series 39 actuators and other quarter-turn valve actuators used in automated process control. It features an integrated I/P converter with a built-in 30 micron filter, supports a supply pressure up to 120 psi with an operating range of 40–120 psi, and carries IP66 / NEMA 4 protection for demanding environments. The unit mounts directly on the actuator (direct actuator-mounted positioner) and uses 1/4 inch NPT process connections with 1/8 inch NPT gauge ports, while operating over -4°F to 185°F (-20°C to 85°C) and weighing about 3.4 lb (3.9 lb with gauges). Key capabilities include split-range operation, reverse-acting control, and adjustable span and zero calibration, making it suitable for industrial process automation in chemical processing, power generation, water and wastewater treatment, steam systems, compressed air networks, and general manufacturing environments where precise valve modulation is required.
