The Sun Hydraulics DOHRXHN (DOHRXHN) is a normally open, balanced poppet switching element designed for hydraulic systems. This valve remains open when the vent port (port 4) is blocked and shifts to a closed position upon venting, provided there is adequate pressure at port 3. It features a unique balanced construction that allows predictable switching at pressures up to 5000 psi (350 bar) at both ports 1 and 2, with a minimum pilot pressure of 400 psi (30 bar) at port 3. The valve opens when pilot pressure drops below 145 psi (10 bar). Ports 1 and 2 are hydraulically balanced and fully sealed from ports 3 and 4, which are also positively sealed, ensuring minimal leakage\u2014typically less than 10 drops/min at 5000 psi. The valve can accommodate an external connection to a pilot switching valve with low leakage requirements; the Sun model DAA solenoid pilot valve is recommended for this purpose. The DOHRXHN model incorporates Sun's floating style construction to reduce the risk of internal binding due to installation torque or machining variations. It fits into cavity T23A, belongs to series 3, and has a capacity of up to 60 gpm (240 L/min). The minimum pilot pressure required to shift the valve is 300 psi (20 bar), with maximum operating pressures reaching up to 5000 psi (350 bar). Its compact design includes a valve hex size of 1-1/4 inches (31.8 mm) and requires an installation torque between 150-160 lbf ft (203-217 Nm). The model weighs approximately 1.45 lb (0.70 kg) and uses Viton seal kits for enhanced durability in various applications.

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.
