Functional engineering application
The BLX-MAL-4200 Manual Air Lever Valve provides rugged, reliable manual directional control for pneumatic actuators, cylinders, workbenches, and lifting mechanisms across Kenyan workshops and processing plants. Featuring an ergonomic, heavy-duty metal hand lever with a non-slip knurled grip, the valve offers positive mechanical detenting that holds the spool securely in the selected position until shifted by the operator. The body is CNC-machined from high-strength aluminum alloy and hard-anodized to resist wear and atmospheric corrosion. Inside, a micro-ground stainless steel spool supported by precision NBR O-rings ensures low actuation force, zero leakage, and long operational life under heavy industrial usage.
Manual hand-lever operated 5/2-way pneumatic spool valve with detented positioning lever, 1/4" BSP ports, hard-anodized aluminum body, and 0-8 bar pressure rating for pneumatic machine control.

Common questions on this part
The BLX-MAL-4200 is detented (bistable). When the operator flips the lever forward or backward, it locks securely in that position until shifted again. Spring-return (momentary) models are also available upon request.
Yes. It connects directly to double-acting pneumatic cylinders (such as the BLX-ISO-4400 or BLX-MRC-4500) using standard G1/4" pneumatic push-in fittings and 8mm or 10mm polyurethane tubing.
Yes. Standard G1/4" sintered bronze or plastic pneumatic silencers screw directly into the two exhaust ports to reduce exhaust air noise and prevent dust ingress.
Yes. The valve collar includes an external panel-mount thread and locking nut, allowing the valve body to be mounted behind a console with only the lever protruding.
Yes. STARNEX stocks BLX-MAL manual valves along with pneumatic tubing and fittings at our Nairobi counter.
