The Sun Hydraulics DOJPKDV (DOJPKDV) is a normally open, balanced poppet switching element designed for precision hydraulic applications. This valve operates by maintaining an open state until the pilot pressure at port 3 reaches the pre-set level defined by the integral pilot relief stage, subsequently shifting to a closed position. It features a unique balanced construction that ensures predictable switching performance under pressures up to 5000 psi (350 bar) at both port 1 and port 2. The valve's design includes hydraulic balancing between these ports, while ports 3 and 4 are positively sealed from them, ensuring minimal leakage\u2014typically less than 10 drops per minute at maximum pressure. The DOJPKDV model is engineered to accommodate high-capacity flow rates of up to 120 gpm (480 L/min) and requires a minimum pilot pressure of 300 psi (20 bar) to shift. Its robust construction includes Sun's floating style design to prevent internal part binding due to installation torque or machining variations. The valve's operational integrity is further enhanced by its ability to accept backpressure at the drain port, which directly adds to the valve setting. Installation specifics include a cavity size of T-24A and a series designation of 4, with recommended installation torque between 350 - 375 lbf ft (475 - 508 Nm). The adjustment screw features an internal hex size of 5/32 in. (4 mm), while the locknut requires a hex size of 9/16 in. (15 mm) and torque of 80 - 90 lbf in. (9 -10 Nm). For sealing purposes, Viton seal kits are available under part number 990024006. Overall, the Sun Hydraulics DOJPKDV is ideal for applications requiring reliable switching under high-pressure conditions with low leakage and precise control over hydraulic flow dynamics.

This is a normally open, balanced poppet, switching element. When pilot pressure is applied to port 3, the poppet remains open until the pilot pressure reaches the setting established by the integral pilot relief stage, at which point the poppet shifts to the closed position.
- Unique balanced construction provides predictable switching with 5000 psi (350 bar) at both port 1 and port 2. When the remote pressure signal at port 3 exceeds the internal valve setting, the valve shifts to the closed position.
- Any backpressure at the drain port is directly additive to the valve setting.
- 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).
- 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.
