OS&Y Gate Valve with Supervisory Switch
Series Gate Valve TS-OSY is used in fire protection applications
for fire main shutoff. The operation of the gate valve is unlike
that of a double disc gate valve. In normal circumstances less
operating torque is required as the resilient wedge valve just
closes, or upon opening. The supervisory switch mounted to the
gate valve alerts when the water supply to the sprinkler system
is tampered with or being shut off. The switch assembly consists
of two SPDT switches and is designed to send a signal when
the valve is closed or when the cover is removed. When the
valve is fully open, the switch is in the neutral position. Closing
the valve causes the switch rod to come out of the valve stem
groove, activating the signal. Removing the cover causes loss of
contact with the switch rod, activating the signal.
