Wireless Transmitter Switches

Outside Screw and Yoke Supervisory Switch

OSY2 and OSY2A outside screw and yoke supervisory switches monitor the open position of an outside screw and yoke (OS&Y) type gate valve. The switches consist of a rugged housing intended for indoor and outdoor use.

Outside Screw and Yoke Supervisory Switch

OSY2 and OSY2A outside screw and yoke supervisory switches monitor the open position of an outside screw and yoke (OS&Y) type gate valve. The switches consist of a rugged housing intended for indoor and outdoor use. When installed with the actuator in the vertical position, the OSY2 switches are NEMA 3R rated per UL. OSY2 switches feature a user-friendly mounting bracket and adjustable shaft to permit mounting to most OS&Y valves from 1 to 12 inches (2.54 to 30.48cm). The right-angle design and wide bracket span provides maximum clearance for valve components, accommodating troublesome valves. Removing the gate valve bracket allows the unit to monitor side-bracket-style pressure reducing valves.

Installation is made easier with a single-side conduit entrance. By providing a direct conduit pathway to the electrical source, right-angle fittings are not required. Installation is further simplified by the adjustable-length actuator, which eliminates the need for cutting the shaft.

The switch is equipped with tamper-resistant cover screws to prevent unauthorized entry. Inside, two sets of SPDT (Form C) synchronized switches are enclosed in a durable terminal block to assure reliable performance.
