The Sun Hydraulics DNCAMTV836 (DNCAMTV836) is a solenoid-operated, 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. This valve is engineered with a closed transition between positions, which significantly minimizes oil loss during shifting\u2014a crucial feature for pilot control circuits. It operates with port 3 as the inlet and port 1 as the tank, although it allows reverse flow, performance in such cases is not assured and thus not recommended. The solenoid tube assembly is rated for fatigue at 5000 psi (350 bar), ensuring durability under high-pressure conditions. Notably, this valve requires no minimum hydraulic pressure to function due to its direct actuation. The DNCAMTV836 incorporates EPDM seals suitable for systems using phosphate ester fluids; however, these seals are vulnerable to petroleum-based substances. A wet armature design means the working fluid surrounds the armature and can be affected by coil-generated heat over time. This can lead to varnish formation in certain fluids like water-glycol mixtures if exposed to prolonged energization. The valve features a high-efficiency solenoid design providing substantial spool actuating force per Watt expended, enhancing reliability in valve shifting operations. Coils are interchangeable with other Sun Series 1 products and offer various termination and voltage options with or without surge protection. The model also includes coil connector options rated up to IP69K for superior environmental protection. With a capacity of 8 gpm (30 L/min) and response time typically around 50 ms, this model supports a maximum operating pressure of 5000 psi (350 bar). The valve demonstrates maximum leakage of 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar) and supports a switching frequency of up to 15,000 cycles/hr. Its floating style construction reduces risks of internal binding due to installation torque or machining variations.
