Description
DN32 Flanged Stainless Steel Solenoid Valve – Shako SPU225F-12
The Shako SPU225F-12 is a DN32 pressure-assisted 2/2 way normally closed flanged solenoid valve manufactured from 316 stainless steel for reliable control of air, water, oils, gases and compatible industrial fluids.
Featuring DN32 PN16 welded 316 stainless steel flanges, a large 38mm orifice and Kv flow factor of 367 L/min, the SPU225F-12 provides excellent flow capacity while maintaining a maximum working pressure of 15 Bar.
A wide choice of sealing materials, WRAS-approved EPDM option, oxygen-degreased preparation and ATEX/IECEx hazardous-area configurations make the valve suitable for demanding water treatment, process, chemical and industrial applications.

WRAS Approved Option
A WRAS-approved EPDM sealing option is available for potable water applications.
This combines the corrosion resistance of the 316 stainless steel valve body with an approved EPDM sealing configuration for drinking-water and potable-water systems.
Oxygen Service Option
The SPU225F-12 can be supplied specially degreased with oil and grease contamination removed for oxygen and clean-gas applications.
✓ Degreased valve preparation available
✓ Suitable for oxygen service when correctly specified
✓ Stainless steel wetted construction
✓ Alternative shading-ring configurations
Seal material and operating conditions should be selected specifically for the oxygen application.
