Parker Hannifin CSPH103P-8T Pilot Operated Check Valve

The Parker Hannifin CSPH103P-8T Pilot Operated Check Valve is a hydraulic valve that uses a pilot signal to control whether the check element is open, allowing forward flow when the pilot is active and preventing backflow when the pilot is inactive. This pilot-operated design provides controlled, pressure-activated flow in circuits where backflow must be blocked until a signal is present, delivering reliable directional control without continuous high-pressure reliance. The CSPH103P-8T is a member of Parker's CSPH line and reflects Parker Hannifin's engineering for hydraulic precision and durability in industrial systems. In operation, applying pilot pressure on the control line enables the valve to open and pass flow in the intended direction, while removing pilot pressure returns the valve to the closed position to maintain blocking in the reverse direction. This configuration is appropriate for hydraulic circuits that require controlled backflow protection and directional control in equipment and machinery environments.
