Alpha Pompe (Alphair) Pneumatic Actuators – Reliable Quarter-Turn Valve Automation

Alpha Pompe Alphair pneumatic actuators — compact rack-and-pinion mechanisms of double-acting and single-acting types for 90°, 120°, 180° rotation. Torque 5–13367 Nm at 8 bar, supply pressure 3–10 bar, operating temperature -60°C…+150°C (options). Extruded aluminum EN AW 6063 T6 body with hard anodizing 50 µm, die-cast aluminum EN AB 46100 T6 pistons anodized 15 µm, covers polyester painted 60-80 µm. Carbon steel shaft nickel-plated 20 µm (option AISI 316). NBR seals (options FPM/FKM, silicone). Low-friction acetal LAT-LUB bearings (option PA66). Pre-compressed painted springs. Supply: dry or lubricated filtered compressed air. Adjustment ±5°.

Compliance with EN ISO 5211, DIN 3337, NAMUR VDI/VDE 3845, ATEX II 2GD c T95°C, EN 15714-3.

Design Advantages

Symmetrical design with reverse rotation, no side loads on pistons/shaft/body. Heavy-duty, compact, reliable. Easy valve assembly/conversion. Guaranteed 1,000,000 operations lubrication.

Double-Acting (AP032–AP420, 5–13367 Nm)

Torque based on 1–10 bar pressure. Low friction, high cycle life.

Single-Acting (AP042–AP420, with springs)

Pneumatic + spring torque (3–6 springs per piston). Safe return on air loss, easy maintenance.
