Engineered Valves

Engineered Valves are essentially a group of Solenoid valves which have been designed in terms of performance, powerconsumption 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 SolenoidValve 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.
  • Manual Reset 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 moredetails. Some of the solutions from above range are also available in the NAMUR and Pulse Jet Valve Program. Please refer therelevant Catalogue of these valve for more details.

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:

 

  • 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.

  • 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.

  • Out of 3 type voting system combining high demand and safety in system using triple redundant control systems to ensure safety and high uptime. These types of system are Installed On Most Critical Operations In Highly Hazardous Process industries.

  • Rotex is in a position to offer solutions for all of the above conditions using a redundancy in operator type principle which essentially combines independent valve operating component arranged in redundant configurations. This concept is most superior to the redundancy in solenoid since it makes the complete valve component redundant to each other reducing the probability of failure of these valves. The system, essentially a single block solution, eliminates all interconnecting point leakage Thereby increasing reliability and ensuring trouble free operation.

  • Especially for pilot operated solenoid valves, rotex offers a solution using redundant operators in application requiring high availability of equipment to avoid spurious tripping. These are classified as valves with redundant operators.

  • Rotex can also offer the Redundant Solenoid Valves with in build non contact type switches to test the system availability for shutdown.

Intrinsically Safe Solenoid Valve with Booster Circuit which is manufactured with fine quality material that procured from reliable vendors in the market. These can be customized on the basis of the specifications of our clients. Our range of is widely acknowledged for excellent performance and superior quality. These are highly appreciated by our customers and they are available at cost effective prices.

Rotex Offers Two Types Of Solutions:

  • Booster Circuit Based Intrinsic Safety.

  • Low Power Intrinsic Safety.

Intrinsically Safe Solenoid uses a Capacitor based storage circuit, which stores the limited power coming from the barrier before firing it across the winding. The Circuit then continues to hold the plunger with the barrier power with this technique, The Is Solenoid can replace an existing solenoid valve having general purpose weather proof or explosion proof solenoid.

This option ss practically available to most solenoid valve with solenoid size 14.

The on time delay of 1.5 second needs to be accounted for while calculating system response time, which may not be suitable for certain applications.This solenoid can certainly used for shut down/ trip circuit applications. In view of this, Rotex also offers another solution with faster response. Intrinsically Safe Solenoid Valve Ex Iaiic, T6 :

Features :

  • Aluminium / Stainless Steel Cast Enclosure.

  • Interchangeable To Weather Proof And Explosion Proof Solenoid Size 14.

  • Response On Time < 1.5 Sec.

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 toope rates without a significant effect on the operating characteristics. Lower Power Consumption also means smaller power supply. Low Power Valve has significant lower temperature rise (<= 30oc 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.

Features :

  • Highly Efficient Operator Capable Of Operating with 0.4w Coil & Pressure Rating Of 8 Bar.
