3/8" High Pressure Brass Solenoid Valve – Shako PU225H-03

25 Bar High Pressure Brass Solenoid Valve – Normally Closed

The SHAKO PU225H-03 is a compact high-pressure 3/8" 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-03 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 compressed air systems

High-pressure water systems

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 substantially higher operating pressures than conventional general-purpose brass solenoid valves.

Its pressure-assisted diaphragm design provides operation from a relatively low 0.5 Bar differential up to 25 Bar, while the stainless steel stem and reinforced diaphragm provide durability for demanding industrial applications. SHAKO specifically highlights the series' low starting pressure, large flow rate, high working pressure and quick response.

The PU225H-03 combines an 8mm orifice, Cv 2.0 and 35mm² effective flow area with a 30 Bar proof/test pressure, providing a compact solution for high-pressure fluid and gas control.

Repair Kits & Maintenance

Replacement diaphragm repair kits are available for the PU225H series with NBR, FKM, EPDM or HNBR sealing options. The SHAKO repair kit consists of the spring, O-ring, diaphragm and plunger.
