Description

3/4" 316 Stainless Steel Solenoid Valve – SPU225A-06


The SHAKO SPU225A-06 is a high-flow 3/4" 316 stainless steel 2/2 way normally closed solenoid valve designed for industrial fluid, water, air and compatible gas control applications.

Its pressure-assisted diaphragm design provides a large 25mm orifice and Kv flow factor of 165 L/min, making it ideal for higher-flow applications where a minimum 0.5 Bar pressure differential is available.

Manufactured from corrosion-resistant 316 stainless steel with stainless steel internals, the SPU225A-06 is particularly suitable for RO water, demineralised water, pure water, AdBlue, chemicals and other compatible fluids. Options include alternative seal materials, oxygen-service degreasing and ATEX-certified coils.

Valve Function & Operation

Function: 2/2 way normally closed
Operation: Pressure-assisted diaphragm
Minimum Operating Differential: 0.5 Bar
Operating Pressure: 0.5 to 10 Bar differential
Maximum Working Pressure: 15 Bar
The valve is closed when de-energised and opens when electrical power is applied to the solenoid coil.

Ports & Flow

Port Size: 3/4" BSPP female
Optional Threads: NPT or Rc
Orifice Size: 25.0mm
Kv Flow Factor: 165 L/min based on water with 1 Bar pressure drop

Construction & Materials

Body Material: 316 stainless steel
Internal Components: Stainless steel
Standard Seal: FKM (Viton®)
Optional Seals:
EPDM
NBR
HNBR

Shading Ring Options

Standard Shading Ring: Copper
Optional Silver Shading Ring: Suitable for AC or DC configurations
Optional No Shading Ring: DC operation, or AC supply using a suitable rectified AC-to-DC DIN connector
These alternative configurations are useful for high-purity and chemically sensitive applications where copper contact with the controlled media is undesirable.

Media Compatibility

Air
Water
RO water
Demineralised water
Pure water
AdBlue
Light oils
Compatible chemicals
Compatible gases
Fluids up to 50 cSt viscosity
Material and seal compatibility should be confirmed for the specific fluid, concentration and operating temperature.

Seal Options & Temperature Range

NBR: -15°C to +80°C
FKM (Viton®): -10°C to +180°C
EPDM: -5°C to +130°C
