The Sun Hydraulics DMDATPN636 (DMDATPN636) is a high-performance solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is designed to operate efficiently with a maximum operating pressure of 5000 psi (350 bar) and features a typical response time of 50 ms. It has a flow capacity of up to 12 gpm (45 L/min), making it suitable for various hydraulic applications. The valve's construction includes a fatigue-rated solenoid tube assembly and interchangeable coils that can be mounted in either direction, enhancing its versatility and ease of use within different system setups. The DMDATPN636 incorporates Sun's floating style construction, which minimizes internal parts binding\u2014this is crucial for maintaining consistent performance even under varying installation torques or cavity/cartridge machining variations. This model is particularly noted for its robust manual override features, with a mechanical life expectancy of approximately 7,000 cycles for models equipped with the D, L, or T control. The manual override requires a force of about 5 lbs at 1000 psi on Port 1 to actuate. Additionally, the valve utilizes wet armature design; therefore, the working fluid surrounds the armature which could be susceptible to heat during prolonged energization. For systems using phosphate ester fluids, cartridges configured with EPDM seals are recommended as exposure to petroleum-based fluids can damage these seals. The maximum leakage at optimal conditions is relatively low at about 5 in\u00b3/min at 3000 psi. The valve also supports high switching frequencies up to 15,000 cycles per hour. Overall, the Sun Hydraulics DMDATPN636 offers reliable performance with its advanced design tailored for dynamic hydraulic systems requiring precise control and durability.

This solenoid-operated 3-way, 2-position cartridge is a direct-acting, balanced spool directional valve.
- The solenoid tube assembly is fatigue rated for 5000 psi (350 bar) service.
- Spools B and R are closed in the transition between their two positions. This results in a higher performance limit at the expense of lower capacity. When used as pilot controls, where capacity is not a factor, the closed transition will provide faster and more consistent response times.
- This valve is direct actuated and requires no minimum hydraulic pressure for operation.
- On models equipped with the D or L control, the detent mechanism in the manual override is meant for temporary actuation. The D, L and T manual control assembly has a mechanical life expectancy of approximately 7,000 cycles.
- 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.
- Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted on the tube in either direction.
- 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.
