Air Torque PT500S12H Pneumatic Actuator 8 Bar

Air Torque PT500S12H is a rack‑and‑pinion pneumatic actuator rated for an 8 bar air supply, designed for precise valve control in industrial automation. This unit ships with ABB TZIDC digital electro‑pneumatic positioner, which translates a control signal into accurate pneumatic output to position the valve stem. The TZIDC is electronically configurable and offers optional 4–20 mA feedback, with a recommended positioner supply range of 1.4–6 bar (20–90 psi) to ensure reliable, repeatable travel. Together, the combination provides controlled, repeatable valve actuation suitable for safety‑critical and regulatory environments, pairing Air Torque’s robust rack‑and‑pinion mechanism with ABB’s positioning technology for dependable performance. The PT500S12H designation identifies the Air Torque PT500 family, with the 8 bar rating indicating the actuator’s nominal operating pressure while the TZIDC handles precision positioning and feedback.
