Spirax Sarco, a products and services provider for steam system management, has released the EP500, the world's first ergonomically designed electropneumatic valve positioner.
The positioner offers very high accuracy and “industry-leading” reliability with an ease of installation, calibration and operation, Spirax Sarco said.
The EP500 has a cast aluminium enclosure that is suitable for outdoor installations, and it utilises simple force-balance control technology and can be mounted onto pneumatic actuators with strokes between 10mm and 70mm.
With two gauges to indicate the supply air pressure and the output pressure to the pneumatic actuator, zero and span adjustments are easily accomplished.
Additional features include improved calibration capabilities, IP65 rated weatherproof enclosure, NAMUR mounting, and an easily accessible and electrical access cap with compression style wiring connectors.
