Rotex solenoid valve Engineered Valves
|
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:
All these valves feature changes in either internal components or External shape and thus are classified under a completelynew 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. 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. |

INTRINSICALLY SAFE SOLENOID VALVE :
By lowering the power Consumption below the ignition energy level the Solenoid valve is inhibited from being the cause of an explosion. Thus the term Intrinsically Safe Solenoid Valve.
Intrinsically Safe Solenoid valve offers the highest protection available for product installed in Hazardous / Explosive environment. With protection class Ex ia, IIC, T6 this Solenoid valve can be installed in application / equipment falling under zone 0, zone1 and zone 2. (Ex ia certified equipment is only permitted to be used in zone 0 area).
It is worth remembering that Intrinsic Safety is for a complete circuit, of which solenoid valve is one component along with a certified Barrier. In absence of the Barrier, the valve is merely a low power consuming device, which then depending upon the type of enclosure used may not be suitable for installing in Hazardous area.
All of ROTEX Intrinsically safe Solenoid solutions are certified Ex ia IIC, T6.
ROTEX offers two types of solutions :
•Booster circuit based Intrinsic safety.
•Low Power Intrinsic safety.
Booster circuit design (Type 62, 63, 64) :
Intrinsically safe Solenoid uses a capacitor ba
Latch Type Solenoid Valve :
WORKING PRINCIPLE :
In Fluid Control applications where sudden/ momentary loss of power which can result in safety issues, create a major shut down, affecting up time and in applications where continuous power consumption affects the life of power supply, Latch coil solenoid valves offer the ideal solution.
Using a Magnetic Latching principle, the Latch type solenoid has two coils with opposing windings and a permanent magnet.The solenoid has three terminals, for latching (energizing) and De-latching (de- energizing).
On energizing the Latch coil (either by a pulse of power or continuous power), plunger is pulled and latched magnetically.
The Latch solenoid is designed for continuous energization in case the application demands. Loss of power or switching off the Latch coil will not change the valve position. Momentary pulse to the De-latch coil will de-energize the solenoid valve.Optionally a manual override can also manually Latch/manually De-latch the Solenoid valve.
The Latch type Solenoid system has been designed in a manner to facilitate conversion of single solenoid valve to a stay put the device i.e. on power failure to retain l
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 pressure rating are higher than most other makes in a similar class thus offering a more reliable operation and longer life.
The ROTEX Lower Power Intrinsically safe Solenoid Valve is suitable for 210 µm filtered air having a -20°C 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 tc. 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 solut
LOW POWER SOLENOID VALVE
Low power solenoid valve is usually with power consumption below 5 Watt.This valve uses improvised Solenoid operator & a solenoid enclosure with suitably modified electo magnetic parameters. The power consumption is lowered without much effect on the pulling force.
This ensures that even with low power consumption, Valve continues to Operates without a significant effect on the operating characteristics. Lower Power consumption also means smaller power supply. Low Power valve has significant lower temperature rise (<= 30 OC degree, on Continues energization). This offers much longer life for the solenoid.
The valves are available for both AC & DC operating Voltage & in a variety of enclosures like DIN plug, Integral Junction box weather as well as Explosion proof.

Highly efficient operator capable of operating with 0.4W coil & pressure rating of 8 bar.
Direct acting valve can be supplied with 5W coil.

FEATURES :
Valve operated when solenoid is energized.
Valve retains the position when power to the solenoid is removed.
Most of the valves are reset by turning knob clockwise when power to the solenoid is switched off.
Wide varieties of 2 - 3 ports valve can be supplied.
Continuous duty rated solenoid.
Can be supplied with most voltage, current.
Can be supplied with weather proof / Explosion proof solenoid.
Ambient / Fluid Temperature : - 20 °C to 80 °C
Media :
Air, Inert Gases, Water, Oil
Application:
Manual reset OFF valve (latching on de-energization) switches ON when energized.
Valve does not switch OFF when de-energized till switched OFF manually.
This type of valve is used where the valve is required to remain ON even though supply to the solenoid is switched OFF.
Eg. Firefighting, Clamping, Blow Down application etc.

Manual Reset Solenoid Valves are used in applications and processes demanding utmost safety checks before starting / stopping the process.In all such application, human intervention is the final check before the process is taken into/ taken off the auto mode.
Based on the nature of the process, the solenoid valves are required to stop the process from starting automatically in case of an emergency or vice versa. These valves are called Manual Reset valves with Latching on Energization. They are also referred to as no voltage Release or Free handle type Manual reset.
ROTEX offers this series of valves in three constructions :
Manual Reset, Latching ON Energization :
Manual Reset, where in the Manual Reset button is used to compliment the power supply provided to the solenoid. On pressing the Manual Reset button, the plunger is lifted and latched electrically. The Valve trips when the power to the solenoid valve is removed.
With this feature, ROTEX offers a comprehensive range of Manual Reset solenoid valves in 2 Port, 3 Port and 5 Port constructions.
Manual Reset Tamper Proof :
Where in the valve cannot be operated till either by pressing manual reset
Redundant Solenoid Valve
Redundant function is most popular in ESD (Emergency shut Down) type application. Usually these products are part of the shut down loops and connected to an independent shut down control system which may be Double or Triple redundant.
Depending upon the application demand, three types of redundant systems are in use:
1.) Out of 2 type voting system for high safety loops where in tripping of any
of the switching circuit will trip the application.This is typically required
for critical circuits where in failure to shut down safely can have
catastrophic consequences.
2.) Out of 2 type voting System for high demand loops requiring high
uptime avoiding spurious trips due to equipment malfunctions. These
types of systems are called for in mission critical application where
in equipment failure can result in heavy losses for plant.
3.) Out of 3 type voting system c
