ATEX Ex d Normally Open Solenoid Valve – Rotex 20202 / 20202V01


The Rotex 20202 and 20202V01 are high-performance ATEX Ex d explosion-proof 2/2 way normally open solenoid valves designed for hazardous-area applications requiring reliable fail-open operation, high pressure capability and extremely fast cycling.

With a normally open, energise-to-close design, the valve automatically returns to the open position when electrical power is removed. Direct acting operation eliminates the need for a minimum pressure differential and allows operation from high vacuum through to pressures up to 120 Bar, depending on the selected orifice.

The standard valve features a 316 stainless steel CF8 body with stainless steel internals, with brass and aluminium body options also available. Bubble-tight shut-off, 9G vibration resistance, switching rates up to 1000 cycles per minute and a life expectancy exceeding 10 million cycles make the range particularly suitable for demanding process and automation applications.

Valve Function & Operation

Function: 2/2 way normally open
Operation: Direct acting
The outlet connection is positioned at the top of the valve. In its normal de-energised state, the valve remains open, allowing media to flow. Applying electrical power closes the valve.
This provides fail-open operation, making the 20202 / 20202V01 particularly useful where flow must automatically resume or remain available following loss of electrical power.
Because the valve is direct acting, it requires no minimum pressure differential.
Pressure range: 0 to 120 Bar according to orifice
Vacuum capability: Down to 10⁻⁶ Torr

Ports, Orifices & Flow

Available BSP port sizes:
1/8", 1/4", 3/8" and 1/2"
NPT threaded versions are available as an option.
Available orifices:
0.8mm
1.2mm
1.6mm
1.8mm
2.2mm
2.5mm
3.0mm
3.5mm
4.0mm
5.0mm
Water flow ranges from approximately 0.5 to 9 L/min at 1 Bar pressure drop, depending upon the selected orifice.
The maximum working pressure also varies according to orifice size, allowing the valve to be configured to balance pressure capability against required flow.

Construction & Materials

Standard body: 316 stainless steel CF8
Optional bodies: Brass or aluminium
Internals: Stainless steel
Shading ring: Copper
Optional shading ring: Silver or none
The 316 stainless steel version provides excellent corrosion resistance for demanding industrial, process and hazardous-area installations.

Seal & Media Options

Available sealing materials include:
NBR
FKM (Viton®)
EPDM
PTFE / FKM
Hytrel
Suitable media include high vacuum, air, water, gases and other fluids compatible with the selected seals and materials of construction.
Correct seal selection should be based on the media, temperature and operating conditions of the application.

High-Speed Industrial Performance

The Rotex 20202 / 20202V01 is particularly well suited to applications involving frequent switching or continuous production machinery.
Bubble-tight shut-off
Vibration resistance: Up to 9G
Maximum cycling: 1000 cycles/minute
Life expectancy: >10 million cycles
This combination of high cycling capability and long expected operating life provides a significant advantage in demanding automated process applications.

Typical Applications

The Rotex 20202 / 20202V01 is particularly suitable for hazardous-area applications requiring normally open or fail-open control, including oil and gas installations, petrochemical plants, chemical processing, high-pressure gas control, vacuum systems, analyser equipment, process skids, compressed air, water systems, industrial automation and OEM machinery.
Why Choose the Rotex 20202 / 20202V01?
The combination of normally open fail-safe operation, direct acting control, high vacuum capability and pressures up to 120 Bar makes this range particularly versatile.
Its ability to cycle at up to 1000 operations per minute, together with a life expectancy exceeding 10 million cycles, bubble-tight shut-off and 9G vibration resistance, makes it especially attractive for demanding hazardous-area automation where both reliability and switching frequency matter.
