3/8" Brass Steam Solenoid Valve – Shako PU225S-03

High Temperature Brass Steam Solenoid Valve – 10 Bar, +180°C

The SHAKO PU225S-03 is a compact 3/8" pressure-assisted 2/2 way normally closed brass solenoid valve designed specifically for steam and high-temperature fluid control applications.

Featuring a forged brass body, stainless steel internals, piston-assisted operation and PTFE sealing, the valve provides reliable control of steam up to 10 Bar and +180°C. It can also be used with air, water and compatible gases and fluids at pressures up to 15 Bar.

Its 13mm orifice provides high flow capacity from a compact valve, making the PU225S-03 particularly suitable for industrial steam systems, heating equipment, autoclaves, hot water systems and OEM machinery.

Typical Applications

Steam control systems

Industrial boilers and heating equipment

Autoclaves and sterilisation equipment

Hot water systems

Food and beverage processing

Why Choose the PU225S Steam Solenoid Valve?

Unlike a general-purpose solenoid valve adapted for higher temperatures, the SHAKO PU225S series uses a pressure-assisted piston design specifically suited to steam and hot fluid control.

The combination of PTFE sealing, stainless steel internals and Class H coil allows the standard valve to control steam at temperatures up to +180°C and pressures up to 10 Bar, while air, water and compatible gases can be controlled at pressures up to 15 Bar.

The pressure-assisted design requires only 0.5 Bar differential pressure while providing high flow through the 13mm orifice.
