Winn-Marion Electro-Pneumatic Positioner, 3-15psi

Durable cast aluminum, polyester housing that is NEMA 4X rated. All stainless steel retained fasteners. Thick cam that is double locked with sturdy cam nut. The bottom plate helps absorb vibration. Simple calibration screwdriver slots in the span and zero ferrules, along with an external zero adjustment, helps make setting up the positioner simple. The minimum interaction between zero and span means you can make a span adjustment without always returning to zero, saving valuable time. The pilot valve assembly can be easily cleaned (dry alcohol base) by removing one screw. The unique O-ring gasket prevents loss of individual O-rings in the cleaning process. The assembly can then be easily re-installed in only one direction, with a design that automatically "pinches" the upper lever leaf spring that is used to help stabilize the pilot. I/Ps can be changed, removed, converted in minutes and the I/P test points on the small connection board make checking the I/P or the circuit very simple. I/P can be installed, removed, or converted at any time while still mounted on the actuator (rotary or linear). Standard indicator can be reversed to direct or reverse acting and always show the proper scale (0-100%). Flat or raised indicators. F05 mounting hole pattern with multiple drive options that can be field converted.
