Valve positioners
Series 3731 explosion-proof valve positioners from Samson Controls are designed for process control applications which demand the highest levels of safety and reliability.
These intrinsically-safe positioners are said to provide impressive durability and accuracy, and be easy-to-operate. A single rotary pushbutton is all that is required for start-up: turn to select parameters and push to activate them.
This convenient operation method is possible in hazardous areas because the shaft design of the rotary pushbutton through the housing is explosion-proof. The enclosure design with its separate terminal compartment, also allows direct cable entry or connection without spark barriers for cable conduit systems.
