The Sun DTDA MHN is a high-performance, pilot-to-close, spring-biased closed, balanced poppet logic element. This screw-in hydraulic cartridge valve is designed to block flow from port 1 to port 2. A pilot pressure signal at port 3 will close the valve, effectively stopping flow. The balanced poppet design ensures that back-pressure at port 2 has minimal effect on the required pilot pressure. Manufactured by Sun Hydraulics, this valve is known for its reliability and durability in demanding hydraulic applications, including load-holding, blocking, and circuit control. It fits into the standard T-11A cavity, making it a versatile component for various manifold designs.
