The Sun Hydraulics DNCALZV836 (DNCALZV836) is a solenoid-operated, 4-way, 2-position cartridge valve featuring a direct-acting, balanced spool design. This directional valve is engineered for applications where minimizing oil loss during transitions is crucial, such as in pilot control circuits. It operates with port 3 as the inlet and port 1 as the tank, although reverse flow is possible, it may not maintain optimal performance. 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 for activation due to its direct actuation mechanism. Designed with a wet armature system, the DNCALZV836 allows the working fluid to surround the armature, which can be advantageous or disadvantageous depending on fluid type and operational duration. For instance, water-glycol mixtures may degrade over time when exposed to heat generated by the coil. The valve offers various coil termination and voltage options with optional surge protection to meet diverse application needs. Its high-efficiency solenoid design provides significant actuating force per watt, enhancing reliability in valve shifting. The DNCALZV836 incorporates Sun's floating style construction to reduce internal binding risks from installation torque or machining variations. It features a cavity size of T-31A and has a capacity of 8 gpm (30 L/min). The maximum operating pressure stands at 5000 psi (350 bar), with typical response times around 50 ms and maximum leakage rates of 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar). Additionally, it supports switching frequencies up to 15,000 cycles per hour and includes manual override capabilities. Coils are interchangeable within Sun's Series 1 products and can be mounted in either direction for added flexibility.

This solenoid-operated, 4-way, 2-position cartridge is a direct-acting, balanced spool directional valve. The transition between positions is closed. The closed transition greatly reduces the loss of oil when shifting which can be of particular importance in pilot control circuits.
- Valve capacity is based on port 3 as the inlet and port 1 as the tank. Although reverse flow is possible, the same performance cannot be guaranteed and is not recommended.
- The solenoid tube assembly is fatigue rated for 5000 psi (350 bar) service.
- This valve is direct actuated and requires no minimum hydraulic pressure for operation.
- Cartridges configured with EPDM seals are for use in systems with phosphate ester fluids. Exposure to petroleum based fluids, greases and lubricants will damage the seals.
- This valve utilizes a wet armature design. This means that the working fluid surrounds the armature and is exposed to the heat generated by the coil. This can be a factor if the coil is energized for long periods of time. Some fluids, notably water/glycol mixtures, break down at these temperatures over time and form varnishes that will affect the function of the cartridge.
- A wide variety of coil termination and voltage options are available, with and without surge protection. See the CONFIGURATION section.
- The solenoid's unique magnetic design results in a high efficiency solenoid, yielding high spool actuating force per Watt expended, leading to reliable valve shifting.
- Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted on the tube in either direction.
- Coil connector options offer ratings up to IP69K. See individual coil product pages for details. Additional weatherized coils and kits are available for more complete environmental protection.
- Incorporates the Sun floating style construction to minimize the possibility of internal parts binding due to excessive installation torque and/or cavity/cartridge machining variations.
