Removing the OSY2’s gate valve bracket allows the unit to monitor side-bracket style pressure reducing valves. 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 require. Installation is further simplified by the OSY2’s adjustable length actuator, which eliminates the need for cutting the shaft.
