The Sun Hydraulics DMDALPV936 (DMDALPV936) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for robust hydraulic control in various applications. This direct-acting, balanced spool directional valve operates with a rapid and consistent response time of approximately 50 ms, ideal for systems requiring precise control dynamics. With a maximum operating pressure of 5000 psi (350 bar) and a flow capacity of up to 12 gpm (45 L/min), it suits high-pressure environments effectively. The DMDALPV936 features closed transitions between spool positions B and R, enhancing performance by reducing capacity only where it is not a critical factor, such as in pilot controls. This design choice ensures faster switching frequencies up to 15,000 cycles per hour without sacrificing system integrity. The valve's manual override is equipped with a detent mechanism designed for temporary actuation, supporting mechanical life expectancy around 7,000 cycles. This model uses EPDM seals suitable for systems utilizing phosphate ester fluids; however, they are sensitive to petroleum-based fluids which can cause seal degradation. The wet armature design of the valve means that the working fluid surrounds the armature which might be susceptible to heat during prolonged energization periods\u2014a consideration when using certain hydraulic fluids. For versatility in installation and maintenance, the DMDALPV936's coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Additionally, it incorporates Sun\u2019s floating style construction that minimizes internal parts binding caused by excessive installation torque or variations in cavity/cartridge machining. This model adheres to stringent quality standards ensuring reliability and durability in demanding operational conditions.

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.
