ATEX Ex d 3/2 Universal Solenoid Valve – Rotex 30309-10-4

The Rotex 30309-10-4 is a high-flow ATEX Ex d explosion-proof 3/2 way universal solenoid valve designed for demanding hazardous-area process and industrial control applications.

Its universal 3-way configuration allows a single valve to be piped for normally closed, normally open, diverting or mixing operation. The direct acting design operates from high vacuum through to 10 Bar without requiring a minimum pressure differential, while the large 10mm orifice provides a water flow rate of approximately 30 L/min at 1 Bar pressure drop.

Available with aluminium, brass or 316 stainless steel CF8 bodies, the 30309-10-4 combines bubble-tight shut-off, 9G vibration resistance, switching rates up to 800 cycles per minute and a life expectancy exceeding 20 million cycles.

Valve Function & Operation

Function: 3/2 way universal

Operation: Direct acting

The universal port configuration enables the Rotex 30309-10-4 to perform four different control functions:

3/2 Normally Closed – primary flow is closed when the solenoid is de-energised.

3/2 Normally Open – primary flow remains open when the solenoid is de-energised.

Diverting – directs a single inlet between two alternative outlets.

Mixing – allows two inlet paths to be switched towards a common outlet.

Because the valve is direct acting, it operates from zero differential pressure, making it suitable for vacuum and low-pressure applications as well as positive pressures up to 10 Bar.

Pressure, Orifice & Flow

Operating pressure: 0 to 10 Bar

Vacuum capability: Down to 10⁻⁶ Torr

Orifice: 10mm

Water flow: 30 L/min at 1 Bar pressure drop

The relatively large 10mm orifice provides substantially higher flow than many conventional direct acting 3/2 hazardous-area solenoid valves.

Ports & Connections

Available BSP port sizes:

1/4"

3/8"

1/2"

NPT threaded connections are available as an option.

Construction & Materials

Body options:

Aluminium

Brass

316 stainless steel CF8

Internals: Stainless steel

With the stainless steel body option, the internal components are also 316 stainless steel.

Shading ring: None

The choice of three body materials allows the valve configuration to be matched more closely to the media, environment and required corrosion resistance.

Seal & Media Options

Available seal materials:

NBR

FKM (Viton®)

EPDM

Viton® GLT

Fluorosilicone

Suitable media include:

High vacuum

Air

Water

Gases

Compatible process fluids

Media compatibility should be confirmed against the selected body and seal materials for the particular application.

Performance & Reliability

The Rotex 30309-10-4 is designed for demanding industrial switching applications:

Bubble-tight shut-off

Vibration resistance: Up to 9G

Maximum cycling: 800 cycles/minute

Life expectancy: >20 million cycles

Mounting position: Any position

This combination of high cycling capability, large flow orifice and long expected service life makes the valve particularly suited to automated process systems.

Manual Reset Option

An optional manual reset facility is available with the brass and stainless steel body versions.

This option can be useful where the valve must remain in a defined state following an electrical event until manually reset by an operator.

ATEX Ex d Explosion Protection

The Rotex 30309-10-4 uses an ATEX-certified flameproof solenoid operator designed for hazardous gas and dust environments.

ATEX certificate: TI22ATEX 278X

ATEX marking: II 2GD

Gas protection: Ex db IIC T6 / T5 Gb

Dust protection: Ex tb IIIC T80°C / T95°C Db

Protection: IP66 / IP67

Ambient temperature:

T6: -40°C to +55°C

T5: -40°C to +70°C

The Ex d enclosure can be supplied in either aluminium or 316 stainless steel, with M20 × 1.5 or 1/2" NPT horizontal conduit entry.

Coil & Electrical Specification

Coil: II 18mm

12V DC: LW15 – 15 Watts

Other voltages: LW20 – 20 Watts

Insulation: Class H

Protection: IP66 / IP67

Surge suppression: Included

Available voltages:

12V DC

24V AC/DC

48V AC/DC

110V AC/DC

230V AC/DC

Voltage tolerance: ±20%

Except for the 12V DC version, the ATEX coils are rectified and accept either AC 50/60Hz or DC input at the specified voltage.

Typical Applications

Typical applications include hazardous-area process control, oil and gas installations, petrochemical plants, chemical processing, industrial gas systems, high-vacuum equipment, process skids, analyser systems, diverting and mixing circuits, pneumatic control systems and specialist OEM machinery.

Why Choose the Rotex 30309-10-4?

The standout feature of the 30309-10-4 is its combination of universal 3/2 operation with a large 10mm direct acting orifice.

One valve can provide normally closed, normally open, diverting or mixing control while operating from high vacuum through to 10 Bar. Combined with 30 L/min water flow, ATEX Ex d protection, 800 cycles/minute capability and a life expectancy exceeding 20 million cycles, it provides a highly versatile solution for demanding hazardous-area applications.
