The detecting function of the main valve position detects a mismatch between the input signal and valve operation.
Category 2 ：Safety function can be accomplished by single channel and is automatically checked.
When the dual residual pressure release valve is used, if one of the valves fails to operate, the other one releases residual pressure.
Category 3 ： It has redundancy so there is no loss of safety function with a single failure. The safety function must be checked before each use. An accumulation of undetected faults can cause loss of safety function.
Category 4 ： It has redundancy so there is no loss of safety function with a single failure. The safety function must be checked before each use. An accumulation of undetected faults does not affect the safety function. (Higher DC and MTTFd than Category 3.)
* This product is component which is a part of a safety system and safety equipment is not guaranteed by this single unit alone.
