Double Pilot Check Valve
The Demcon Double Pilot Check Valve is an internally piloted, high-performance fluid control valve engineered to lock double-acting hydraulic cylinders securely in position. Manufactured by Demcon Fluid Power Industries in Bengaluru, this valve prevents fluid from escaping the cylinder when the control valve is centered. It holds heavy loads indefinitely and ensures safety against catastrophic load-dropping if a line or hose breaks.

About this item
The Demcon Double Pilot Check Valve (manufactured by Demcon Fluid Power Industries in Bengaluru) is a high-reliability fluid control device designed to lock double-acting hydraulic cylinders securely in both directions. It eliminates position drift by preventing fluid from leaving the cylinder until pilot pressure is deliberately applied from the opposite line.
