Description
ISO 5599-1 Sub-Base 5/2 Pneumatic Solenoid Valve – PS520 Series
The Shako PS520 Series is a high-flow 5/2 way ISO pneumatic solenoid valve designed for reliable directional control of double-acting pneumatic cylinders and actuators in industrial automation systems.
Available in ISO 1 and ISO 2 mounting sizes, the PS520 mounts directly onto standard ISO sub-bases or multi-station manifold systems, providing a modular solution for machine building, control panels and replacement of compatible ISO-pattern pneumatic valves.
Single-solenoid spring-return and double-solenoid versions are available, with internal pilot operation, aluminium alloy construction, IP65 protection and optional explosion-protected coils for hazardous-area applications.

Single Solenoid Operation
The single-solenoid PS520 uses internal pilot operation with spring return.
Power ON → The pilot valve shifts the main spool, directing compressed air to one actuator port while exhausting the opposite port.
Power OFF → The spring returns the spool to its normal operating position, reversing the airflow.
This configuration is ideal where a defined valve position is required when electrical power is removed.
Double Solenoid Operation
The double-solenoid PS520 provides bistable directional control.
Energising one solenoid shifts the valve to one operating position. Energising the opposite solenoid shifts the valve to the reverse position.
The spool remains in its last selected position after the electrical signal is removed until the opposite solenoid is energised.
ISO Sub-Base & Manifold Mounting
The PS520 Series is designed for modular installation using matching ISO-pattern mounting components.
Available options include:
✓ Single sub-base
✓ Multi-station manifold sub-base
✓ Left and right end plates
✓ 2-station manifold
✓ 3-station manifold
✓ Larger multi-station manifold assemblies
Explosion-Protected Coil Options
The manufacturer's ordering system provides three explosion-protected coil configurations:
E1 – Explosion-proof 22mm width
E2 – Explosion-proof 30mm width
E3 – Explosion-proof CSA standard
The PS520 catalogue refers to the separate explosion-proof coil specification for the detailed certification and hazardous-area ratings.

ISO Replacement Applications
The standardised ISO mounting arrangement makes the PS520 particularly useful for replacement and refurbishment of pneumatic machinery where an existing ISO-pattern directional valve is fitted.
Always confirm the ISO size, mounting interface, pneumatic port arrangement and electrical specification before replacing another manufacturer's valve.
Typical Applications
Double-acting pneumatic cylinders
Pneumatic actuators
Industrial automation
Machine building
Factory automation
Packaging machinery
Assembly equipment
Pneumatic control panels
Multi-station valve manifolds
