Industrial VSA-3511-33 2-Position Pneumatic Valve

The Versa VSA-3511-33 is a 3-way, 2-position pneumatic directional control valve with a 1/2-inch brass body, designed to handle vacuum to 200 PSIG and regulate compressed air in industrial automation and fluid power systems. It uses a subplate mounting style with external pilot and spring-return actuation, delivering reliable, fail-safe valve operation in compact control panels. The valve supports compressed air and compatible pneumatic fluids, making it suitable for factory automation, pneumatic actuators, conveyors, assembly lines, process equipment, and packaging systems where precise 3-way switching and vacuum-to-pressure performance are required. OEMs, system integrators, and maintenance personnel typically use the VSA-3511-33 for replacements, retrofit projects, preventive maintenance, and restoration of pneumatic system performance in industrial environments; common replacements include Versa VSA-3511-167, Versa VIZ-3511-LOVB, and Versa VPP-3511-31.
