The Sun Hydraulics DMDADNV (DMDADNV) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for robust hydraulic control. With a direct-acting, balanced spool directional mechanism, this valve ensures precise operation without the need for minimum hydraulic pressure. It features spools B and R that are closed during the transition between positions, optimizing performance by providing faster and more consistent response times ideal for pilot control applications where capacity is less critical. This model is rated for up to 5000 psi (350 bar) and has a flow capacity of 12 gpm (45 L/min), making it suitable for demanding hydraulic systems. The manual override option includes a detent mechanism intended for temporary actuation with a mechanical life expectancy of about 7,000 cycles. Additionally, the DMDADNV incorporates EPDM seals specifically for use with phosphate ester fluids; however, these seals are sensitive to petroleum-based products which can cause damage. The wet armature design of the valve allows the working fluid to surround the armature, potentially affecting fluid properties if exposed to heat over extended periods. This valve's construction minimizes internal parts binding and accommodates varying installation conditions due to its floating style construction. Interchangeable coils from Sun Series 1 solenoid products add versatility in maintenance and replacement processes, ensuring easier handling and compatibility across different setups. The robust manual override requires minimal force even under high pressure conditions, highlighting its user-friendly design despite its industrial capabilities. This model also stands out with its quick response time of typically 50 ms and operational reliability reflected in its maximum switching frequency of 15,000 cycles per hour.
