Rotex offers a wide range of 2 Port Solenoid Valves to suit variety of applications. These valves can be basically classified as Normally Closed or Normally Open based on the valve condition when the solenoid is energized. Further they can be classified as Direct Acting, Diaphragm Operated, Internal / External Pilot Operated.

Pressure range : up to 400 bar.Operated temperature between 0 C to 80 C.Orifice 0.5mm to 80mm thus offering a wide range of flow rates.Mounting Any position.Life : above 10 million cycles.Body : Anodized Aluminium, Brass, SS316.Seal : NBR, Viton, EPDM, PTFE.

Our special 2 Portdiaphragm solenoid valve isoffered with special high grade polymer like Hytrel which is superior to synthetic rubberslike NBR, Neoprene etc.

Rotex offers a wide range of3 Port Solenoid Valves to suit variety of applications.

Engineered Valves are essentially a group of Solenoid valves which have been designed in terms of performance, power consumption or protection to suit the most demanding application in the process Industries. These valves offer high technical solution to various application calling for a control element beyond a conventional Solenoid Valve by combining advanced designs, new production techniques and testing.

ROTEX offers a wide range of solutions under this program classified under five categories:
Intrinsically Safe Solenoid Valve
Low Power Solenoid Valve
Impulse Operated Valve with Latch type Solenoid
Redundant Solenoid Valve

All these valves feature changes in either internal components or External shape and thus are classified under a completely new series.

Many of these solutions were identified differently prior to the release of this catalogue. ROTEX can provide the equivalent Model identification from earlier series to new series for the convenience of the customer. Please contact ROTEX for more details.

Some of the solutions from above range are also available in the NAMUR and Pulse Jet Valve Program. Please refer the relevant Catalogue of these valve for more details.

Low power Intrinsic Safety Solenoid System works with a High Efficiency pilot operator to ensure maximum flux linkage between core and plunger, thus improving pulling force.
The maximum allowable orifice for the pilot valve is smaller than the Non IS Solenoid valve and IS solenoid valves using Booster Circuit. However the flow Orifice and the pressure rating are higher than most other makes in a similar class thus offering a more reliable operation and a longer life.

The ROTEX Lower Power Intrinsically safe Solenoid Valve is suitable for 210 um filtered air having a -20C Dew point. The valve is most suitable to harsh operating conditions and results in a trouble free operation.

Power consumption of 0.14 Watt at 12V DC is also the lowest, in a similar class, demonstrating the advanced technology being used by ROTEX in these valves.

The valves are directly compatible to remote I/O terminals of various manufacturers like Simens, ABB, Turk, MTL and Stahl etc. for use in field BUS applications involving PROFIBUS DP-IS and PROFIBUS PA networks.Since there is a change in the valve construction, this group of Valves have been classified under a new range with a wide variety of solutions in 2 port, 3 port, and 5 port configuration in both Direct acting and pilot operated versions. Three different Solenoid constructions are available depending on the cabling needs :DIN Plug (Type 65CR), suitable for flexible cable with a PG9 cable entry.With Integral Terminal Box (Type 67 or 68) in epoxy coated Aluminium or (Type 67-CO or 68-CO) SS 316 construction suitable for armoured cable with gland (mainly for applications in Hydro carbon, Oil and Gas and Petrochemical industries, requiring high safety from Explosion Risk).

Rotex intrinsically safe Solenoid is certified as per IS/ EN/ IEC 60079-0 and 60079-18 for Ex ia IIC T6 standards ROTEX have approval for ATEX, INDIAN : CCOE, DGMS, INMETRO, GOST ROTEX also offers a complete range of NAMUR solenoid valve with Intrinsic Safety.

The Cabinet has logic for.
1. Operating actuator when the line pressure is healthy (within the set limits)
2. Operating actuator for partial stroking.
3. Manual Reset function ie to close the actuator when line pressure falls either below or above set value and once closed the actuator does not operate even it line pressure is resumed, till the same is set manually.
System Pressure : 150 bar
Signal Pressure : 3 16 bar
