The Sun Hydraulics DMDA-MRN is a high-performance, pilot-operated, balanced poppet logic element. This normally closed cartridge valve is engineered to reliably block flow from port 1 to port 2. Flow is initiated when sufficient pilot pressure is applied at port 3, opening the valve. Its innovative balanced poppet design ensures that the pilot pressure required for operation is minimally affected by pressure at either port 1 or 2. This feature provides stable and predictable performance, making the DMDA-MRN ideal for a variety of hydraulic circuit applications, including directional, pressure, or flow control. Designed to fit into a standard T-11A cavity, this valve is a versatile and durable solution for demanding hydraulic systems.
