Description
1/4" 5/2 Way Single Solenoid Pneumatic Valve – PU52002S
The PU52002S is a high-flow 1/4" 5/2 way single solenoid pneumatic valve designed for reliable directional control of double-acting pneumatic cylinders and actuators.
Its internal pilot operation provides fast, dependable switching, while the spring-return design automatically returns the valve to its normal position when electrical power is removed.
Manufactured with a surface-anodised aluminium body, the PU52002S features a lockable manual override, 18mm² effective flow area and 100% continuous-duty coil. Individual or manifold mounting and an optional ATEX / IECEx explosion-protected coil make it suitable for industrial automation, OEM machinery and hazardous-area pneumatic control applications.

Single Solenoid Operation
Energising the solenoid shifts the valve spool, reversing the compressed-air supply and exhaust connections to operate a double-acting pneumatic cylinder or actuator.
When electrical power is removed, the internal spring automatically returns the valve spool to its normal position, reversing the actuator direction.
The lockable manual override allows valve operation during commissioning, machine setup, maintenance and functional testing without electrical power.
Mounting Options
Individual body-mounted installation
MF520 manifold systems
Multi-station manifold assemblies are available for compact pneumatic control installations.
Typical Applications
Double-acting pneumatic cylinders
Double-acting pneumatic actuators
Industrial automation
OEM machinery
Packaging equipment
Assembly machinery
Process control systems
Pneumatic control panels
Material handling equipment
Machine automation
Multi-valve manifold systems
General compressed air installations
Quality & Reliability
The PU52002S combines a robust surface-anodised aluminium body with high-flow internal pilot operation and spring return for dependable pneumatic directional control.
Its 18mm² effective flow area, lockable manual override and manifold mounting capability make it particularly suitable for automated machinery requiring reliable control of double-acting pneumatic cylinders and actuators.
