Swagelok SC00030-4U F05F07-N-DS-14 AZNX MS-A30-4DIN Rotary Actuator

Swagelok MS-A30-4-DIN is an ISO 5211-compliant pneumatic actuator that delivers a precise 90° rotation with spring return, designed to drive Swagelok ball valves and other 63-series valve actuations in quarter-turn installations. The actuator operates with compressed air to move from an open to closed position and automatically returns to its default state when air pressure is removed. It uses a DIN mounting pattern with flange size F05 and, for compatibility with Swagelok mounting brackets and 4-DIN valve assemblies, it carries the MS-A30-4-DIN designation. The physical footprint aligns with Swagelok's A30 family geometry, with nominal dimensions: A 3.35 in (85.0 mm), B 0.55 in (14.0 mm), and C 1.97 in (50.0 mm). This combination of standardization, compact form, and spring-return behavior makes it suitable for automation loops that require reliable, repeatable quarter-turn actuation in restricted spaces.
