Description

ATEX Ex ia 150 Bar Solenoid Valve – Rotex 20101

The Rotex 20101 is an ATEX and IECEx Ex ia intrinsically safe high-pressure solenoid valve designed for hazardous-area applications requiring low-power electrical control combined with direct-acting operation at pressures up to 150 Bar.

Featuring a 2/2 way normally closed, direct-acting design, the valve operates without a minimum pressure differential and can control applications ranging from high vacuum through to positive pressures of 150 Bar, depending on the selected orifice.

Standard construction uses a 316 stainless steel CF8 body with stainless steel internals, with brass or aluminium body options available. The Rotex 20101 combines bubble-tight shut-off, 9G vibration resistance, switching speeds up to 1000 cycles per minute and a life expectancy exceeding 10 million cycles.

Valve Function & Operation

Function: 2/2 way normally closed

Operation: Direct acting

The Rotex 20101 remains closed when the solenoid is de-energised and opens when the intrinsically safe electrical signal is applied.

Its direct-acting construction means the valve does not require upstream pressure or a minimum differential pressure to operate.

Operating pressure:

0 to 150 Bar depending on orifice

This makes the valve particularly useful for applications where pressure may fall to zero or where conventional pilot-operated high-pressure valves would be unsuitable.

High Vacuum to High Pressure

The Rotex 20101 provides an unusually broad operating envelope:

High vacuum: Down to 10⁻⁶ Torr

Positive pressure: Up to 150 Bar

Maximum allowable pressure depends on the selected orifice and valve configuration.

This combination of high-vacuum capability, zero differential operation and high positive pressure makes the valve suitable for demanding process and instrumentation applications.

Ports & Connections

Available BSP connections:

1/8" BSP

1/4" BSP

3/8" BSP

1/2" BSP

Optional NPT threads are available.

Orifice & Flow Options

Available orifices:

0.8mm

1.2mm

1.6mm

1.8mm

2.2mm

2.5mm

3.0mm

3.5mm

4.0mm

5.0mm

Water flow: 0.5 to 7 L/min at 1 Bar pressure drop

Both maximum pressure and flow depend on the selected orifice, so the required pressure, flow and connection size should be considered together when specifying the valve.

Construction & Materials

Standard body:

316 stainless steel CF8

Optional body materials:

Brass

Aluminium

Internals:

Stainless steel

Shading ring:

Copper standard

Silver optional

Without shading ring optional

The standard 316 stainless steel construction provides a robust option for demanding industrial and hazardous-area process installations.

Seal & Media Compatibility

Available seals:

NBR

FKM (Viton®)

EPDM

PTFE / FKM

Hytrel

Suitable media include:

High vacuum

Air

Water

Gases

Compatible process fluids

The appropriate body and seal combination should be selected according to the medium, pressure, temperature and chemical compatibility requirements of the application.

Performance & Reliability

The Rotex 20101 combines intrinsically safe electrical operation with impressive mechanical performance:

Bubble-tight shut-off

Vibration resistance: Up to 9G

Maximum cycling: 1000 cycles/minute

Life expectancy: >10 million cycles

These characteristics make the valve suitable for high-cycle automated applications as well as conventional process control.

Low-Power Ex ia Solenoid

Coil: Rotex III 14mm

Nominal voltage: 24V DC

Operating power: 2.3 Watts

Booster circuit: 8 Watts

Insulation: Class H

Protection: IP67

The integrated booster circuit provides increased power during initial valve actuation while allowing the intrinsically safe operator to function at its lower operating power.

Electrical entry options:

1/2" NPT

M20 × 1.5

Entry orientation: Bottom entry

ATEX & IECEx Intrinsic Safety

Approvals:

ATEX

IECEx

IECEx certificate:

IECEx BAS 12.0128X – Issue 1

ATEX certificate:

Baseefa12ATEX0243X – Issue 1

Gas marking:

Ex ia IIC T5 Ga

-60°C ≤ Ta ≤ +75°C

Ex ia IIC T6 Ga

-60°C ≤ Ta ≤ +60°C

Dust marking:

Ex ia IIIC T200 125°C IP67 Da

-60°C ≤ Ta ≤ +75°C

The Ga and Da equipment protection levels make the operator suitable for very high levels of hazardous gas and dust protection when correctly incorporated into a compliant intrinsically safe system.

Intrinsically Safe Parameters

Minimum operating parameters:

Voltage: 10V

Current: 20mA

Power: 0.20W

Entity parameters:

Ui: 32V DC

Ii: 230mA

Pi: 2.3W

Li: 0

Ci: 0

The associated intrinsically safe barrier or galvanic isolator must be selected to comply with these certified entity parameters while also providing the minimum electrical requirements necessary for reliable valve operation.

Typical Applications

The Rotex 20101 is particularly suited to hazardous-area high-pressure process systems, instrumentation, compressed gas control, vacuum systems, oil and gas installations, chemical and petrochemical plants, refineries, process skids, test equipment and other applications requiring intrinsically safe control from vacuum through to high pressure.

Why Choose the Rotex 20101?

The major advantage of the Rotex 20101 is the combination of Ex ia intrinsic safety, direct-acting zero-differential operation and pressures up to 150 Bar.

It provides an intrinsically safe alternative to an Ex d high-pressure valve where electrical energy must be limited at the hazardous-area device rather than contained within a flameproof enclosure.

The standard 316 stainless steel body, ten available orifice sizes, high-vacuum capability, 9G vibration resistance and >10 million cycle life provide considerable flexibility for demanding process applications.
