Allenair AV 3 X 2 1 2 SDS-PK-120V Hydraulic Cylinder

The Allenair AV 3 × 2-1/2 SDS-PK-120V hydraulic cylinder is a valve-in-head, double-acting unit with a 3‑inch bore and a 2.5‑inch stroke. This AV-series model integrates the hydraulic control valve into the cylinder head and employs a double‑solenoid (SDS) coil at 120 V to govern flow, enabling electrical actuation without an external valve block. By combining valve and actuator in one compact package, the design reduces leak points and the number of fittings and tubing connections required. The AV family covers bores from 1-1/8” to 4” and a range of stroke lengths, and this configuration delivers repeatable push/pull motion for compact automation tasks. Typical applications include clamping, indexing, and light pressing in industrial automation environments, where precise, controlled hydraulic movement is needed and wiring can be routed to standard control panels. The SDS variant signals a dual‑coil setup for reliable cycling, and this model’s 120 V coil value aligns with common electrical control systems found in manufacturing settings.
