Limit Switch Settings

At time of shipment from the factory, the limit switches are set to give a signal at full valve open and closed positions. On "rate-set" valves, that is valves on which the limit stops are set to limit the valve opening so as to regulate flow, the resetting of the "valve open" switch is extremely simple.

After the limited valve open positions has been established, it is simply necessary to loosen the lock-nut on the switch actuator arm - move the adjusting screw upward until the upper switch trips, then re-tighten the lock-nut.
