The Sun Hydraulics DOJSXHE (Material Number: DOJSXHE) is a normally open, balanced poppet switching element designed for high-pressure hydraulic systems. It operates by utilizing pilot pressure at port 3 to shift the valve to a closed position. The unique balanced construction of this valve ensures predictable switching performance with a maximum operating pressure of 5000 psi (350 bar) at both ports 1 and 2, provided the external drain is open and the minimum pilot pressure is maintained at 300 psi (20 bar). The design includes fully sealed ports 1 and 2 from ports 3 and 4, with positive sealing on ports 3 and 4, ensuring minimal leakage\u2014typically less than ten drops per minute at maximum pressure. The valve is hydraulically balanced between port 1 and port 2, allowing it to open when the pilot pressure falls below 145 psi (10 bar). It incorporates Sun's floating style construction to minimize internal binding risks due to excessive installation torque or cavity machining variations. This product is suitable for systems using phosphate ester fluids when equipped with EPDM seals; however, exposure to petroleum-based fluids will damage these seals. The DOJSXHE fits into a T-24A cavity and has a capacity of up to 120 gpm (480 L/min). Its installation requires a torque of between 350 and 375 lbf ft (475 - 508 Nm), making it robust for demanding applications.

This is a normally open, balanced poppet, switching element. Pilot pressure at port 3 shifts the valve to the closed 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 300 psi (20 bar).
- 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).
- Cartridges 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.
- Valve will open 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.
