The Sun Hydraulics DODRXHV (DODRXHV) is a normally open, balanced poppet switching element designed for high-pressure hydraulic systems. This valve remains open when the vent port (port 4) is blocked and shifts to a closed position when vented, provided there is adequate pressure at port 3. Its unique balanced construction allows for predictable switching with pressures up to 5000 psi (350 bar) at both ports 1 and 2, requiring a minimum pilot pressure of 400 psi (28 bar) at port 3. The valve opens when pilot pressure drops below 145 psi (10 bar). The DODRXHV features hydraulic balancing between ports 1 and 2, with complete sealing from ports 3 and 4, ensuring minimal leakage\u2014typically less than 10 drops per minute at full pressure. Port connections can handle up to 5000 psi (350 bar), making this valve suitable for demanding applications. The valve incorporates Sun's floating style construction to reduce internal binding risks due to installation torque or machining variations. With a capacity of up to 15 gpm (60 L/min), the DODRXHV fits into the T-21A cavity and requires an installation torque of between 30-35 lbf ft (41-47 Nm). It weighs .35 lb (.15 kg) and uses a Viton seal kit for durability in various environments. This component is ideal for applications needing reliable switching under high-pressure conditions with low leakage rates, such as in hydraulic circuits requiring precise control over fluid flow paths through pilot-operated mechanisms.

This is a normally open, balanced poppet, switching element. When the vent port (port 4) is blocked, the poppet remains in the open position. Venting port 4 shifts it to the closed position, provided there is sufficient pressure at port 3.
- Unique balanced construction provides predictable switching with 5000 psi (350 bar) at both ports 1 and 2, with the vent (port 4) open and a minimum pilot pressure of 400 psi (30 bar) at port 3.
- Valve will open when the pilot pressure falls below 145 psi (10 bar).
- 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.
- 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).
- Port 4 may be externally connected to a pilot switching valve. The pilot valve should have a leakage rate of less than 10 drops/min. and be able to satisfy the pilot flow requirements. Sun model DAA*-*** solenoid pilot valve is ideal for this application.
- 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.
