The Sun Hydraulics DKDSXHN/LH (DKDSXHN/LH) is a high-performance hydraulic valve designed for precise fluid control in various applications. This model is a normally closed, balanced poppet, switching element that operates efficiently under high-pressure conditions up to 5000 psi (350 bar) at both ports 1 and 2. It features a unique balanced construction which ensures predictable switching and reliable operation with a minimum pilot pressure of 400 psi (30 bar). The valve transitions to the open position when pilot pressure is applied at port 3. Constructed to accommodate systems using phosphate ester fluids, the DKDSXHN/LH cartridges are equipped with EPDM seals, which are resistant to these fluid types but should not be exposed to petroleum-based fluids as they can cause damage to the seals. The valve maintains very low leakage rates between port 1 and port 2, typically less than 10 drops/min at 5000 psi (0.7 cc/min at 350 bar), ensuring efficient system operation. Furthermore, this model incorporates Sun's floating style construction which minimizes the risk of internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. This feature contributes significantly to the longevity and reliability of the valve in demanding operational environments. The DKDSXHN/LH also supports a maximum flow capacity of 15 gpm (60 L/min), making it suitable for a wide range of hydraulic applications where precise fluid control is essential.

This is a normally closed, balanced poppet, switching element. Pilot pressure at port 3 shifts the valve to the open position.
- Unique balanced construction provides predictable switching with 5000 psi (350 bar) at both ports 1 and 2, with the external drain open and a minimum pilot pressure of 400 psi (30 bar).
- 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.
- These valves are hydraulically balanced between port 1 and port 2.
- Port 1 and port 2 are fully sealed from port 3 and port 4. Ports 3 and 4 are positively sealed.
- Any backpressure at the drain port is directly additive to the required pilot pressure for reliable operation.
- Leakage rate between port 1 and port 2 is very low, typically less than 10 drops/min. at 5000 psi (0,7 cc/min at 350 bar).
- Valve will reseat when the pilot pressure falls below 145 psi (10 bar).
- All ports will accept 5000 psi (350 bar).
- 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.
