Description

ATEX Ex ia Intrinsically Safe 3/2 Solenoid Valve – Rotex 30125 / 30201 / 30301

The Rotex 30125, 30201 and 30301 are ATEX and IECEx Ex ia intrinsically safe 3/2 way solenoid valves designed for hazardous-area process control applications where extremely low electrical power, high reliability and flexible valve functions are required.

The range includes 3/2 normally closed, normally open and universal configurations, with direct acting operation from high vacuum through to 20 Bar depending on function and orifice size. The universal 30301 can be configured for normally closed, normally open, diverting or mixing duties.

Manufactured as standard with a 316 stainless steel CF8 body and 316 stainless steel internals, these valves combine bubble-tight shut-off, resistance to vibration up to 9G, switching rates up to 1000 cycles per minute and a life expectancy exceeding 10 million cycles.

Valve Functions

The range provides three distinct 3/2 valve configurations:

Rotex 30125 – 3/2 Normally Closed

The pressure port is closed in the de-energised state. Energising the intrinsically safe solenoid changes the flow path.

Maximum pressure: 0 to 20 Bar, according to selected orifice.

Rotex 30201 – 3/2 Normally Open

Provides normally open operation where the primary flow path remains open without electrical power.

Maximum pressure: 0 to 20 Bar, according to selected orifice.

Rotex 30301 – 3/2 Universal

The universal configuration provides greater installation flexibility and can be piped for normally closed, normally open, diverting or mixing duties.

Maximum pressure: 0 to 14 Bar, according to selected orifice.

All three versions are direct acting, so no minimum operating pressure differential is required.

Ports, Orifices & Flow

Available BSP port sizes:

1/8"

1/4"

3/8"

1/2"

NPT threaded connections are available as an option.

Available orifices:

1.2mm

1.6mm

2.2mm

2.5mm

3.0mm

Water flow ranges from approximately 0.7 to 4 L/min at 1 Bar pressure drop, according to the selected orifice.

Construction & Materials

Standard body: 316 stainless steel CF8

Optional bodies: Brass or aluminium

Internals: 316 stainless steel

Shading ring: Copper

Optional shading ring: Silver or none

The 316 stainless steel construction provides excellent durability and corrosion resistance for demanding process, chemical, offshore and industrial environments.

Seal & Media Options

Available sealing materials include:

NBR

FKM (Viton®)

EPDM

PTFE / FKM

Hytrel

Suitable media include:

High vacuum

Air

Water

Industrial gases

Compatible process fluids

Media suitability should be confirmed against the selected seal material and valve materials of construction.

High-Speed Performance

In addition to hazardous-area certification, the Rotex 30125 / 30201 / 30301 range provides impressive mechanical performance:

Bubble-tight shut-off

Vibration resistance: Up to 9G

Maximum cycling: 1000 cycles/minute

Life expectancy: >10 million cycles

This makes the range particularly suitable for frequently operated process and automation systems where both intrinsic safety and long service life are important.

ATEX & IECEx Intrinsic Safety

The solenoid operator is certified for intrinsically safe installations in hazardous gas and dust atmospheres.

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 this intrinsically safe operator suitable for applications requiring a very high level of protection, subject to installation in accordance with its certification and entity parameters.

Intrinsically Safe Electrical 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 circuit, barrier or isolator must be selected and installed in accordance with these certified entity parameters and the requirements of the hazardous-area installation.

Typical Applications

The Rotex Ex ia 3/2 range is particularly suited to oil and gas installations, petrochemical plants, chemical processing, analyser systems, process instrumentation, pneumatic control circuits, high-vacuum equipment, offshore installations, process skids and other hazardous environments where intrinsically safe electrical operation is required.

Why Choose Rotex 30125 / 30201 / 30301?

This range combines Ex ia intrinsic safety with true direct acting 3/2 control, providing operation from high vacuum without requiring pilot pressure or a minimum differential.

With NC, NO and universal functions, pressures up to 20 Bar, 316 stainless steel construction, 1000 cycles/minute capability and a life expectancy exceeding 10 million cycles, it provides a particularly versatile solution for critical hazardous-area control systems.
