The Sun Hydraulics DOJRXHV (DOJRXHV) is a normally open, balanced poppet switching element designed for precise hydraulic control. This valve remains open when the vent port 4 is blocked and shifts to a closed position when vented, given there is sufficient pressure at port 3. Its unique balanced construction allows predictable switching at high pressures of up to 5000 psi (350 bar) at both ports 1 and 2, with the vent port open and a minimum pilot pressure of 400 psi (30 bar) at port 3. The hydraulically balanced design between ports 1 and 2 ensures minimal leakage, typically less than 10 drops/min at full pressure. Ports are fully sealed from each other to prevent cross-contamination, with ports 3 and 4 positively sealed for optimal performance. The valve's capacity is rated at 120 gpm (480 L/min), with a requirement for a minimum pilot pressure of 300 psi (20 bar) to shift the valve effectively. It incorporates Sun's floating style construction to minimize potential binding issues due to excessive installation torque or machining variations in the cavity/cartridge. The DOJRXHV model fits into cavity T-24A and weighs approximately 3.50 lb (1.60 kg). For installation, it requires a torque between 350 \u2013 375 lbf ft (475 \u2013 508 Nm). This component is ideal for applications requiring reliable hydraulic switching under high-pressure conditions, where low leakage rates are crucial. It can be externally connected to a pilot switching valve with specific flow requirements, such as the Sun model DAA solenoid pilot valve, which complements its operational capabilities effectively.

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.
- 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.
- 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.
