Retrofit Ball Valve Switch

The Model RBVS is designed to monitor the fully open or closed position of a ball valve installed in a sprinkler system as well as monitor the position of a coil on a solenoid for a preaction/deluge system. The unit will fit on most ball valves installed on back-flow-preventers and alarm trim lines of dry, alarm, and deluge sprinkler valves. The switch operates if the ball valve handle is moved from the normal position. However, the switch does not track the position of the handle or ball. When the ball valve handle is under the RBVS plunger, a spring-loaded actuator will contact the valve handle. When the handle is moved from the position, this actuator extends to the tripped position, and the RBVS contacts change state, thereby opening or closing a circuit.
