Robust Construction. The OSY2 consists of a rugged housing,

intended for indoor and outdoor use. When installed with the

actuator in the vertical position, the OSY2 is NEMA 3R rated per UL.

Application Flexibility. The OSY2 features a user-friendly

mounting bracket and adjustable shaft to permit mounting to most

OS&Y valves, ranging in size from 1˝ to 12˝. Its right angle design

and wide bracket span provides maximum clearance for valve

components, to accommodate troublesome valves. Removing the

OSY2’s gate valve bracket allows the unit to monitor side-bracket

style pressure reducing valves.

Simplified Operation. Installation is made easier with the

OSY2’s 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 OSY2’s adjustable length

actuator, which eliminates the need for cutting the shaft.

Reliable Performance. The OSY2 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.
