Description
1/2" 50 Bar High Pressure Brass Solenoid Valve – PU225X-04
SHAKO Normally Closed High Pressure Piston Solenoid Valve
The SHAKO PU225X-04 is a high-pressure 1/2" pressure-assisted 2/2 way normally closed brass solenoid valve designed for demanding fluid and gas control applications at pressures up to 50 Bar.
The valve is closed when de-energised and opens when energised, providing a fail-closed solution for high-pressure industrial systems.
Featuring a forged brass body, SUS304 stainless steel piston and PTFE piston sealing, the PU225X-04 combines high-pressure capability with excellent flow capacity and quick response. Suitable for compressed air, water, light oils and compatible non-corrosive fluids and gases.
Typical Applications
High-pressure pneumatic systems
Compressed air installations
High-pressure water systems
Industrial process control
Pressure testing equipment
Light oil systems
OEM machinery
Process plant equipment
Industrial automation systems

UK Patent: GB2480100
The PU225X series is specifically engineered for high-pressure operation, combining a pressure-assisted stainless steel piston with PTFE sealing for reliable operation at pressures up to 50 Bar.
Why Choose the PU225X High Pressure Valve?
The PU225X is designed for applications requiring considerably higher working pressure than a conventional industrial solenoid valve while retaining a compact, high-flow design.
The PU225X-04 combines 50 Bar maximum operating pressure, 75 Bar proof/test pressure and a 13mm orifice with Kv 64.35 L/min, making it particularly suitable for demanding industrial fluid and gas control systems.
Benefits
✓ High-pressure capability up to 50 Bar
✓ 75 Bar proof / test pressure
✓ Large 13mm flow orifice
✓ Fast-response piston design
✓ PTFE piston sealing
✓ SUS304 stainless steel piston
✓ Fail-closed operation
✓ Compact forged brass construction
✓ Serviceable piston and armature
