Series 3731 explosionproof valve positioners are housed in a rugged enclosure. Even if an explosive atmosphere forms inside the enclosure and ignites — the enclosure withstands the explosion to prevent passage of flames out of explosive surroundings.
These intrinsically-safe positioners are accurate and easy to operate. A single rotary pushbutton is all that’s required for startup then turn to select parameters and push to activate. This operation is possible because shaft design of the rotary pushbutton through the housing is explosionproof, emphasizes the manufacturer. Enclosure design with its separate terminal compartment also allows direct cable entry or connection without spark barriers for cable conduit systems.
Series 3731 comprises an easy-to-read crystal display which ensures relevant data are visible at a glance. Regardless of valve mounting position, data are never displayed upside down since the display rotates 180° via pushbutton.
