Rexroth (AVENTICS) R412012745 Polyamide Valve Positioners For Emergency Shut‑Off Control

📌 Product Overview

The Rexroth R412012745 (AVENTICS) is a polyamide‑constructed manual valve positioner actuator, specially designed for emergency shut‑off control of pneumatic directional control valves. It provides two‑position detent locking function for valve spool, to hold valve at defined switching status for safety interlock and emergency cut‑off. As mechanical operating head for AP‑series pneumatic valves, it converts manual rotary operation into valve spool displacement, realizes reliable emergency shut‑off, manual override and local valve status indication. Widely used for new pneumatic system assembly and MRO spare‑part replacement of industrial safety pneumatic circuits.

✨ Product Advantages

• High‑strength Polyamide Housing Fiberglass‑reinforced polyamide construction, lightweight, impact‑resistant, anti‑corrosion, suitable for general industrial workshop environments.
• 2‑Position Detent Locking Mechanism Clear notched two‑position rotary switching, firmly maintains valve working position, prevents accidental mis‑operation for emergency shut‑off safety requirement.
• Direct Matching for AP‑Series Pneumatic Valves Standard mechanical interface, can be assembled onto Rexroth AP series directional valves with simple adapter kit, easy on‑site retrofit and replacement.
• Wide Ambient Temperature Adaptability Operates stably within broad temperature range, performs well in cold workshop and normal industrial condition, reliable for long‑term safety interlock duty.
• Compact Mechanical Structure Small installation footprint, purely mechanical actuation, no power consumption, low failure rate, minimal maintenance demand.
