Description

ATEX Ex d Stainless Steel Solenoid Valve – Rotex 24102 / 24202


The Rotex 24102 and 24202 are heavy-duty ATEX Ex d explosion-proof stainless steel solenoid valves designed for hazardous-area fluid and gas control applications requiring high flow, reliable shut-off and robust industrial construction.

Available as either 2/2 way normally closed (24102) or 2/2 way normally open (24202), the range covers port sizes from 1/2" to 3" BSP with flow orifices from 12mm to 80mm. Pressure-assisted operation provides high flow capacity at working pressures from 1 to 20 Bar, subject to maintaining the required 1 Bar minimum pressure differential.

Manufactured with a 316 stainless steel CF8 body and stainless steel internals, the range is suitable for demanding process, chemical, petrochemical, gas and industrial applications. ATEX Ex d coils are supplied with IP66/IP67 protection and are available with either aluminium or 316 stainless steel enclosures.

Valve Function & Operation

The range is available in two fail-state configurations:
Rotex 24102 – 2/2 way normally closed. The valve remains closed when de-energised and opens when electrical power is applied.
Rotex 24202 – 2/2 way normally open. The valve remains open when de-energised and closes when electrical power is applied, providing fail-open operation.
Both versions use a pressure-assisted design and require a minimum 1 Bar pressure differential for correct operation.
Operating pressure: 1 to 20 Bar
Maximum cycling rate: 100 cycles/minute
Expected service life: >2 million cycles
Vibration resistance: up to 9G
Shut-off: Bubble tight

Ports, Orifice & Flow

Available BSP port sizes:
1/2", 3/4", 1", 1½", 2", 2½" and 3"
NPT threaded versions are available as an option.
Orifice sizes range from 12mm to 80mm, according to valve size, providing water flow rates from approximately 60 to 1000 L/min at 1 Bar pressure drop.
This broad size range makes the 24102 / 24202 suitable for both smaller high-pressure control duties and large-bore process applications requiring substantially higher flow.

Construction & Materials

Body: 316 stainless steel CF8
Internals: Stainless steel
Shading ring: Copper as standard
Optional shading ring: Silver
No shading ring: Optional
The stainless steel construction provides excellent durability and corrosion resistance for demanding industrial and process environments.

Seal & Media Options

Available seal materials include:
NBR
FKM (Viton®)
Hytrel
Suitable media include air, water, gases and compatible fluids.
Final media suitability should always be checked against the selected seal material and the valve's materials of construction.

ATEX Ex d Explosion Protection

The Rotex 24102 / 24202 range uses an explosion-proof 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 +60°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: III 14mm
Power: 8 Watts
Insulation: Class H
Protection: IP66 / IP67
Surge suppression: Included

Voltage options:

12V DC
24V AC/DC
48V AC/DC
110V AC/DC
230V AC/DC
Voltage tolerance: ±20%
Except for 12V DC, the ATEX coils are rectified and can accept either AC 50/60Hz or DC input at the specified voltage.

Manual Override Option

A push-and-turn M6 manual override is available on the normally closed Rotex 24102 version.
This allows manual valve operation during commissioning, testing or maintenance where required.

Typical Applications

Suitable applications include hazardous-area process control, oil and gas installations, petrochemical plants, chemical processing, industrial gas systems, compressed air, water treatment, process skids, OEM machinery and other Zone-classified installations requiring an ATEX Ex d solenoid valve.
Why Choose the Rotex 24102 / 24202?
The Rotex 24102 / 24202 range combines ATEX Ex d protection, 316 stainless steel construction and port sizes up to 3 inches in a high-flow industrial solenoid valve.
With normally closed and normally open configurations, 1–20 Bar operation, bubble-tight shut-off, 9G vibration resistance and a rated life exceeding 2 million cycles, the range is particularly well suited to demanding hazardous-area installations where reliability and flow capacity are critical.
