Description

3/8" Stainless Steel Normally Open Solenoid Valve – NOSPU225A-03

The Shako NOSPU225A-03 is a 2/2 way normally open pressure-assisted stainless steel solenoid valve designed for reliable high-flow control of air, water, oils, gases and compatible industrial fluids.

Manufactured from 316 stainless steel with a large 13mm orifice, the valve provides a Kv flow factor of 40 L/min and operates across a 0.5 to 10 Bar differential pressure range.

The valve remains open when electrically de-energised and closes when the coil is energised, making it particularly suitable for applications where flow is required to continue following loss of electrical power. WRAS-approved EPDM seals, oxygen-degreased preparation and ATEX/IECEx hazardous-area configurations are also available.

Valve Function & Operation

Function: 2/2 way normally open

Operation: Pressure assisted

De-energised position: Open

Energised position: Closed

Minimum operating pressure: 0.5 Bar differential

Differential pressure range: 0.5 to 10 Bar

Maximum working pressure: 15 Bar

Ports & Flow

Port size: 3/8" BSPP

Optional threads: NPT or Rc

Orifice size: 13.0mm

Kv flow factor: 40 L/min

Based on water with 1 Bar pressure drop.

Construction & Materials

Body: 316 stainless steel

Internal components: Stainless steel

Standard seals: FKM (Viton)

Optional seals:

EPDM

NBR

HNBR

WRAS-approved EPDM seal option available

Standard shading ring: Copper

Optional silver shading ring available for AC or DC operation.

Optional without shading ring for DC operation, or AC supply using a DC coil with a rectified DIN connector.

The alternative shading-ring configurations make the valve particularly suitable for RO water, demineralised water, pure water and AdBlue 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 and internals with an approved EPDM sealing configuration for drinking-water and potable-water systems.

Oxygen Service Option

The NOSPU225A-03 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

✓ 316 stainless steel construction

✓ Alternative shading-ring configurations available

Seal material, pressure, temperature and electrical configuration should be selected specifically for the oxygen application.
