Hydraulic Pilot Operated Check Valve is a specialized valve used in hydraulic systems to control the flow of fluid and prevent backflow. It is designed to allow fluid flow in one direction while blocking the reverse flow, ensuring system safety, and maintaining pressure control.This valve operates through a combination of pilot pressure and mechanical force. It consists of a main check valve and a pilot control valve. The main check valve allows fluid to flow in the desired direction when the pilot control valve is activated by a specific pressure or signal. When the pressure or signal is absent or drops below the required threshold, the pilot control valve closes, effectively blocking the reverse flow and maintaining system pressure.
