Designed for control of hydraulic & pneumatic systems and allow full-flow in one direction.
In-Line Check Valve
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.
The Model LT & LTF Valves will operate satisfactorily when installed in any position. These valves may be used as Line Check Valves, permitting full flow of hydraulic oil in one direction only.
