ATEX Ex d 3/2 Way Solenoid Valve 0–63 Bar – Rotex 30126, 30206 & 30310

The Rotex 30126, 30206 and 30310 are ATEX Ex d explosion-proof 3/2 way solenoid valves designed for hazardous-area control of air, water, gases, vacuum and compatible process fluids.

Available in normally closed, normally open and universal 3/2 way functions, the range uses a direct-acting design requiring no minimum pressure differential.

Normally closed and normally open versions operate from vacuum through to 63 Bar, while the universal version is rated up to 32 Bar.

With 316 stainless steel CF8 construction as standard, bubble-tight shut-off, vibration resistance to 9G and a design life exceeding 10 million cycles, these valves are suited to demanding chemical, petrochemical, gas, process and industrial automation applications.

Valve Function & Operation

Three valve functions are available:

30126: 3/2 way normally closed

30206: 3/2 way normally open

30310: 3/2 way universal

Operation: Direct acting

The direct-acting design allows operation from zero pressure differential and is also suitable for high-vacuum applications down to 10⁻⁶ Torr.

Normally closed and normally open versions are rated up to 63 Bar depending on the selected orifice.

The universal 30310 version is rated up to 32 Bar.

Ports & Connections

Port sizes:

✓ 1/8" BSP

✓ 1/4" BSP

✓ 3/8" BSP

✓ 1/2" BSP

Optional thread: NPT

The range of port and orifice combinations allows the valve to be configured according to the required pressure and flow performance.

Pressure & Flow Performance

Normally closed: 0 to 63 Bar

Normally open: 0 to 63 Bar

Universal: 0 to 32 Bar

Orifice options:

1.2mm

1.8mm

2.2mm

2.5mm

3.0mm

3.5mm

4.0mm

Flow rate: 0.7 to 7 L/min water @ 1 Bar ΔP, depending on orifice.

The combination of direct-acting operation and multiple orifice sizes allows the valve to be selected for either higher-pressure shut-off or increased flow capacity.

Construction & Materials

Standard body: 316 stainless steel CF8

Optional bodies:

✓ Brass

✓ Aluminium

Internal components: Stainless steel

Shading ring: Copper

Optional shading ring:

✓ Silver

✓ Without shading ring

Seal Options

Available sealing materials include:

✓ NBR

✓ FKM (Viton®)

✓ EPDM

✓ PTFE / FKM

✓ Hytrel

Seal selection should be matched to the operating fluid, temperature and application requirements.

Media Compatibility

Suitable for:

✓ Vacuum

✓ Compressed air

✓ Water

✓ Compatible gases

✓ Compatible process fluids

Media must be chemically compatible with the selected valve body, internal components and sealing materials.

High-Speed Industrial Operation

The Rotex 30126 / 30206 / 30310 series is designed for demanding industrial switching applications.

Performance features include:

✓ Bubble-tight shut-off

✓ Vibration resistance to 9G

✓ Switching rates up to 1000/min

✓ Life expectancy >10 million cycles

These characteristics make the range particularly suitable for automated systems requiring rapid and repetitive valve operation.

ATEX Ex d Explosion-Proof Operator

The valve is fitted with a 13W Class H explosion-protected solenoid operator with surge suppression.

Power: 13W

Insulation: Class H

Protection: IP66 / IP67

ATEX marking:

II 2GD

Ex db IIC T6 / T5 Gb

Ex tb IIIC T80°C / T95°C Db

Certificate: TI22ATEX 278X

Ambient temperature:

Three Functions – One Valve Platform

The Rotex range provides three different 3/2 way ATEX solenoid valve functions within the same high-performance platform.

Choose the 30126 normally closed version where the required de-energised condition is closed, the 30206 normally open version where flow must be maintained during power loss, or the 30310 universal version where flexible port configuration is required.

With direct-acting operation, pressure capability up to 63 Bar, high-vacuum compatibility and Ex db / Ex tb hazardous-area protection, the range provides a compact solution for demanding industrial and process control applications.
