The Sun Hydraulics DMDATPV4E12V (DMDATPV4E12V) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for precision hydraulic control. This direct-acting, balanced spool directional valve is well-suited for applications requiring robust performance as it features a fatigue rating for 5000 psi (350 bar) service. The valve's spools, B and R, are closed during the transition between positions which enhances performance at the cost of capacity; however, this is beneficial in pilot control scenarios where speed and consistency are more critical than flow capacity. This unit does not require a minimum hydraulic pressure to operate and incorporates an optional manual override with a detent mechanism on models equipped with D or L control. This feature is intended for temporary actuation and has a mechanical life expectancy of about 7,000 cycles. The EPDM seal configuration makes it suitable for systems using phosphate ester fluids while avoiding exposure to petroleum-based fluids to prevent seal damage. The DMDATPV4E12V utilizes a wet armature design allowing the working fluid to surround the armature which can affect fluid integrity under prolonged energization. Its interchangeable coils are compatible with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Additionally, it employs Sun's floating style construction to minimize internal part binding due to installation torque or machining variations. Notable specifications include a maximum operating pressure of 5000 psi (350 bar), flow capacity up to 12 gpm (45 L/min), and swift response times typically around 50 ms. The valve also supports up to 15,000 switching cycles per hour and requires minimal manual override force. It is designed for easy installation with specific torque requirements and hex size dimensions provided for optimal use. This model\u2019s compact design weighs only about 0.60 lb (0.30 kg), making it versatile for various hydraulic system applications where space and reliability are key considerations.
