1" High Pressure Brass Solenoid Valve – Shako PU225H-08

25 Bar High Pressure Brass Solenoid Valve – Normally Closed

The SHAKO PU225H-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 25 Bar.

Featuring a forged brass body, SUS304 stainless steel internals and a nylon-reinforced diaphragm, the PU225H-08 provides reliable high-pressure operation with quick response and excellent durability. Suitable for compressed air, water, light oils and compatible gases, with alternative seal materials available for improved chemical compatibility.

Typical Applications

High-pressure water systems

Compressed air installations

Industrial process control

Pneumatic equipment

Water treatment equipment

Medical and healthcare equipment

Boiler and utility systems

Light oil systems

OEM machinery

General industrial automation

Why Choose the PU225H High Pressure Valve?

The SHAKO PU225H series is designed for applications requiring considerably higher operating pressures than standard general-purpose brass solenoid valves.

Its pressure-assisted diaphragm design operates from a minimum 0.5 Bar differential up to 25 Bar, while the reinforced diaphragm, forged brass body and stainless steel internals provide a robust solution for demanding industrial fluid and gas control.

The PU225H-08 combines a 1" BSPP connection, 13mm orifice and Kv 64.35 L/min flow capacity with a 30 Bar proof/test pressure, making it suitable for high-pressure pipelines where a larger connection size is required.

Repair Kits & Maintenance

Replacement diaphragm repair kits are available with NBR, EPDM, FKM or HNBR sealing options, allowing the valve to be serviced rather than replaced.
