The Sun Hydraulics DMDALRV636 (DMDALRV636) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic control. This direct-acting, balanced spool directional valve is engineered to function without minimum hydraulic pressure, making it highly effective in a variety of applications. The DMDALRV636 features a fatigue rating for service up to 5000 psi (350 bar), ensuring durability and reliability under high-pressure conditions. Equipped with B and R closed spools in transition, the valve offers superior performance by providing faster and more consistent response times, especially useful in pilot control applications where capacity is less critical. The manual override incorporated in this model is designed with a detent mechanism intended for temporary actuation, supporting mechanical life expectancy around 7,000 cycles. This model also includes EPDM seals suitable for systems using phosphate ester fluids; however, these seals must avoid exposure to petroleum-based substances to prevent damage. Another notable feature is its wet armature design which surrounds the armature with working fluid that can affect temperature-sensitive fluids over prolonged energization periods. For flexibility in installation and maintenance, the DMDALRV636\u2019s coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. The valve also utilizes Sun\u2019s floating style construction to minimize internal parts binding from excessive installation torque or cavity/cartridge machining variations. With specifications like a maximum operating pressure of 5000 psi (350 bar), flow capacity up to 12 gpm (45 L/min), and typical response times of about 50 ms, this valve is an essential component for systems requiring robust and efficient hydraulic control.

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.
