The Sun Hydraulics DOHSXHE (DOHSXHE) is a normally open, balanced poppet switching element designed for high-pressure hydraulic systems. It operates with a pilot pressure at port 3 that shifts the valve to a closed position, providing predictable switching capabilities even under high pressures of up to 5000 psi (350 bar) at both ports 1 and 2, given that the external drain is open. The valve requires a minimum pilot pressure of 300 psi (20 bar) to function effectively, and any backpressure at the drain port will increase the necessary pilot pressure for reliable operation. This model features a low leakage rate between ports 1 and 2, typically less than 10 drops/min at maximum pressure. It also reseats when the pilot pressure falls below 145 psi (10 bar). The DOHSXHE is built with EPDM seals suitable for systems using phosphate ester fluids, while exposure to petroleum-based fluids should be avoided as it may damage the seals. The hydraulically balanced design ensures all ports can handle pressures up to 5000 psi (350 bar), and its floating style construction minimizes internal binding risks due to installation torque or machining variations. This valve fits into cavity T-23A, belongs to Series 3, and has a flow capacity of up to 60 gpm (240 L/min). It requires an installation torque between 150-160 lbf ft (203-217 Nm) and has a hex size of 1\u00bc inches (31.8 mm).

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).
- Valve will reseat when the pilot pressure falls below 145 psi (10 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.
- 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.
