Rotex solenoid valve Engineered Valves REDUNDENT SOLENOID VALVE

 

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 combining high demand and safety in
       system using Triple Redundant control systems to ensure safety
       and high uptime. These types of system are intalled 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, elimiates all interconnecting point leakage thereby increasing reliability and ensuring trouble free operation.

Especially for pilot operated solenoid valves, ROTEX offers a solution using Redudant 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 Redudant Solenoid valves with In build Non Contact type switches to test the system availability for shutdown.
