The Sun Hydraulics DMDADBV636 (DMDADBV636) is a solenoid-operated 3-way, 2-position cartridge valve designed for efficient and reliable hydraulic control. This direct-acting, balanced spool directional valve is particularly suited for applications requiring robust performance with precise control. With a maximum operating pressure of 5000 psi (350 bar) and a flow capacity up to 12 gpm (45 L/min), it is built to handle demanding tasks efficiently. The DMDADBV636 features a wet armature design allowing the working fluid to surround the armature, which can be critical in maintaining temperature stability in the system. It incorporates interchangeable coils from Sun Series 1 solenoid products, enhancing flexibility and ease of maintenance by allowing coils to be mounted in either direction on the tube assembly. The manual override function equipped with a detent mechanism is specifically designed for temporary actuation and has a mechanical life expectancy of about 7,000 cycles. This valve model employs EPDM seals suitable for systems using phosphate ester fluids; however, these seals are susceptible to damage when exposed to petroleum-based fluids. Additionally, the Sun floating style construction minimizes internal parts binding\u2014a common issue arising from excessive installation torque or cavity/cartridge machining variations. The quick response time of approximately 50 ms and the capability to handle switching frequencies up to 15,000 cycles/hr make this valve an optimal choice for rapid operation environments requiring consistent performance. Ideal for use as pilot controls where capacity isn't a primary concern but speed and consistency are crucial, the DMDADBV636 ensures enhanced performance due to its closed transition between spool positions B and R. This feature potentially limits capacity but significantly boosts performance limits by providing faster and more consistent response times compared to open transition designs.
