OS & Y Supervisory Switches
Thông tin chi tiết
The OSYSU is used to monitor the open position of an OS&Y (outside screw and yoke) type gate valve
This device is available in two models; the OSYSU-1, containing one set of SPDT (Form C) contacts and the OSYSU-2, containing two sets of SPDT (Form C) contacts
These switches mount conveniently to most OS&Y valves ranging in size from 2″ to 12″ (50mm to 300mm)
Make sure the groove in the valve stem is at least as wide as the OSYSU roller or trip rod and is at least 1/2″ deep. If not, use a 3/8″ round file on the groove
