The Sun Hydraulics DNDAMUE736 (DNDAMUE736) is a solenoid-operated, 4-way, 2-position cartridge valve that offers reliable and efficient directional control in hydraulic systems. This direct-acting, balanced spool valve does not require a minimum hydraulic pressure for operation, making it versatile for various applications. The solenoid tube assembly is fatigue-rated to withstand up to 5000 psi (350 bar), ensuring durability under high-pressure conditions. This cartridge features multiple manual override options, although manual overrides are incompatible with weatherized coils. Models with the D or L control include a detent mechanism for temporary actuation, with a mechanical life expectancy of approximately 7,000 cycles. The valve's EPDM seals are specifically designed for systems utilizing phosphate ester fluids and should not be exposed to petroleum-based substances. The valve employs a wet armature design where the working fluid surrounds the armature and absorbs heat from the coil. This design consideration is crucial when using fluids like water-glycol mixtures that can degrade under prolonged exposure to high temperatures. A variety of coil termination and voltage options are available, including those with surge protection. The solenoid's magnetic design enhances efficiency by providing high spool actuating force per watt, ensuring dependable valve shifting. Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Coil connector options offer protection ratings up to IP69K for enhanced environmental resistance. The DNDAMUE736 incorporates Sun's floating style construction to reduce potential internal binding due to excessive installation torque or machining variations. It operates at a capacity of 10 gpm (40 L/min) with a typical response time of 50 ms and supports switching frequencies up to 15,000 cycles per hour. The valve features Viton seals and requires specific installation torque settings for optimal performance.
