1" 50 Bar High Pressure Brass Solenoid Valve – PU225X-08


SHAKO Normally Closed High Pressure Piston Solenoid Valve

The SHAKO PU225X-08 is a high-pressure 1" 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-08 combines exceptional pressure capability with a large 25mm orifice for high flow rates. It is suitable for compressed air, water, light oils and compatible non-corrosive fluids and gases.

Patented High Pressure Design

Taiwan Patent: M391595
UK Patent: GB2480100
The PU225X series is specifically engineered for high-pressure operation, combining a pressure-assisted SUS304 stainless steel piston with PTFE sealing for reliable operation at pressures up to 50 Bar.

Why Choose the PU225X High Pressure Valve?

The PU225X-08 combines a full 1" BSPP connection with a 50 Bar operating pressure, 75 Bar proof/test pressure and high-flow 25mm orifice.

Its pressure-assisted stainless steel piston construction makes it particularly suitable for demanding industrial systems where conventional general-purpose diaphragm solenoid valves do not provide sufficient pressure capability.

Typical Applications

High-pressure pneumatic systems
Compressed air installations
High-pressure water systems
High-flow industrial process control
Pressure testing equipment
Light oil systems
OEM machinery
Process plant equipment
Industrial automation systems
