The Sun Hydraulics DODRXHN (DODRXHN) is a normally open, balanced poppet switching element designed for reliable hydraulic control. This component remains open when the vent port 4 is blocked and shifts to a closed position when vented, given sufficient pressure at port 3. Its unique balanced construction allows predictable switching with pressures up to 5000 psi (350 bar) at ports 1 and 2, with a minimum pilot pressure of 400 psi (28 bar) at port 3. The valve opens when pilot pressure drops below 145 psi (10 bar). It features hydraulic balancing between ports 1 and 2, ensuring they are fully sealed from ports 3 and 4, which are also positively sealed. The leakage rate between ports 1 and 2 is very low, typically less than 10 drops/min at maximum pressure. Port 4 can be connected to an external pilot switching valve with minimal leakage requirements; the Sun model DAA solenoid pilot valve is recommended for this purpose. All ports are rated for up to 5000 psi (350 bar), incorporating Sun's floating style construction to reduce internal binding due to installation torque or machining variations. The valve fits into a T-21A cavity, belongs to series 1, and has a capacity of handling flow rates up to 15 gpm (60 L/min). It requires installation torque between 30-35 lbf ft (41-47 Nm) and weighs .35 lb (.15 kg). A Viton seal kit is available under part number 990021006 for maintenance purposes.

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.
