The B5L4-LP MATCO Lever Handle with Lock Plate is a direct-mount actuator for 4" B5 Series butterfly valves. The integrated lock plate allows the valve to be secured in the open, closed, or intermediate position — preventing accidental operation and providing a visual indicator of valve status in the field.

Designed for irrigation systems where quick manual operation and position locking are needed, the B5L4-LP is a practical, durable replacement or upgrade for 4" butterfly valve installations.
