Modular Pilot-Operated Check Valve

The modular pilot-operated check valve (often referred to as a sandwich anti-drift valve) is a critical safety component in hydraulic circuits. In its normal state, it acts as a standard check valve, allowing free flow in one direction and blocking reverse flow. However, when a pilot pressure is applied, the valve unseats, permitting reverse flow. The sandwich (modular) plate design allows it to be stacked directly between the subplate and the directional control valve, eliminating the need for external plumbing.
