VALBIA 82SR0012-SR63S.05 Single Acting Pneumatic Actuator

The Italian VALBIA SR63 S.05, 82SR0012 single-acting pneumatic actuator is widely suitable for the switching and regulation of quarter-turn valves such as ball valves, butterfly valves, and plug valves, and can also be applied in other rotary applications. It is an ideal device for achieving automated control in industrial pipelines.

Structural Features:

Dual-piston symmetrical rack and pinion design ensures fast, smooth operation, high precision, and high output torque. Reverse rotation can be achieved by simply changing the piston assembly position.

The extruded high-quality aluminum alloy cylinder body features precisely machined internal holes and external surfaces treated with hard anodizing (under special conditions, anodizing + Teflon coating), offering an extended service life and low friction coefficient.

Unibody design: All double-acting and single-acting actuator models share the same cylinder body and end caps, allowing easy conversion of action type by adding or removing springs.

Combined pre-loaded safety spring sets enable convenient and safe installation or adjustment of the number of springs, both during assembly and on-site.

Two separate adjustment screws on the external side provide exceptional convenience for actuators already installed on valves, allowing adjustment of the open and closed positions. For full-stroke adjustment, longer screws are provided on both end caps.

Multi-functional position indicator offers visual on-site indication and complies with VDI/VDI 3845 and NAMUR standard slots. It can accommodate and output all accessories, such as limit switch boxes, electro-pneumatic positioners, and position sensors (e.g., Pepperl+Fuchs, Turck).

The air source interface complies with NAMUR standards, allowing direct installation of NAMUR standard solenoid valves.

Composite bushings on the back of the rack, piston guide rings, and output shaft bearings prevent metal-to-metal friction, enhance lubrication, and ensure low friction and long service life.

All fasteners are made of stainless steel for long-term corrosion resistance.

Connection parts comply with the latest ISO 5211 and DIN 3337 (F03-F25) standards, ensuring interchangeability and universality during installation.
