Shut-Off Valves Overview

Durable and Dependable Components to Shut Off Flow

The Lee Company offers two types of shut-off valves – bypass valves and flow fuses. Bypass valves are hydraulically piloted to shut off the flow, while flow fuses shut off flow when the flow rate through the valve reaches a defined limit.

SPEAK TO A SALES ENGINEER
  • Lee bypass valves are 3-port valves that use a unique compression seal to eliminate bypass leakage and any need for additional O-rings. Lee bypass valves are designed to shunt flow across an actuator piston when the system pressure is shut off or lost.
  • Flow fuses are found throughout critical hydraulic systems. In a system breach, the fuse will sense an increase in flow rate and shut off. A flow fuse can also function as a vent valve to purge trapped air or vapor from a fluidic system, such as a fuel system during engine start-up.
