Description

The OSYSU-EX-O is designed to supervise the position of an Outside Screw & Yoke type gate valve in hazardous outdoor locations. The device mounts on the valve to monitor the rising stem. When properly mounted, the trip rod will be resting in a groove filed into the valve stem. When the valve stem begins to move, caused by closing the valve, the trip rod will be pushed out of the groove and activate the switch. To aid with installation the trip rod length is adjustable. This device features a UL listed explosion proof switch enclosure.

Testing

The operation of the OSYSU-EX-O and its associated protective monitoring system shall be inspected, tested, and maintained in accordance with all applicable local and national codes and standards and/or the Authority Having Jurisdiction (manufacturer recommends quarterly or more frequently). A minimum test shall consist of turning the valve wheel towards the closed position. The OSYSU-EX-O shall operate within the first two revolutions of the wheel. Fully close the valve and ensure that the OSYSU-EX-O does not restore. Fully open the valve and ensure that the OSYSU-EX-O restores to normal only when the valve is fully opened
