The BT OSY-1 is a supervisory switch designed to monitor whether an OS&Y gate valve is open or closed. Mount the switch on the valve so that it does not block valve movement. The switch must trigger within two full turns of the handwheel, or before the stem moves one-fifth of its total travel distance. The unit features one SPDT contact and a cover secured by tamper-proof screws (special key included). It is UL and FM approved for both indoor and outdoor installations.
