The Sun Hydraulics RDJA LCN is a high-performance, direct-acting, relieving pressure reducing cartridge valve engineered for demanding hydraulic systems. Designed to regulate and maintain a constant reduced pressure in a sub-circuit, it protects components from over-pressurization by relieving excess fluid to the tank. The valve features a durable threaded steel body that installs seamlessly into a standard T-11A cavity, with precisely machined bottom flow ports for optimal fluid dynamics. Equipped with a standard screw adjustment and a distinctive red O-ring seal for superior leak prevention, the RDJA LCN model delivers robust, reliable pressure control for industrial and mobile applications.
