A hydraulic pilot oil resource valve, also known as a pilot-operated relief valve, is a type of valve used in hydraulic systems to control pressure. It is commonly employed in applications where accurate pressure control is required.
The purpose of a hydraulic pilot oil resource valve is to regulate the flow of hydraulic fluid in response to changes in pressure. It consists of a main valve and a pilot valve. The pilot valve is typically connected to a remote control pressure source, often referred to as a pilot line or pilot port.
