Model LO - Pilot Operated Check Valves

LO Lock Valves are designed to lock a cylinder, or part of a circuit, without leakage while a control valve is in a neutral position. Lock Valves function as check valves, allowing flow to a cylinder and blocking reverse flow until pilot pressure is applied to "unlock" the circuit. These valves may be used to prevent movement of a load while the pressure source is inactive.

Ball/Spring Checks
Note: Capacity (nominal): 25 gpm
Maximum Operating Pressure: 3000 psi

Models LT & LTF Line Check Valves
