The Sun Hydraulics DOJPKDN (DOJPKDN) is a normally open, balanced poppet switching element designed to provide precise control in hydraulic systems. This component remains open until pilot pressure at port 3 reaches a preset level determined by an integral pilot relief stage, prompting the poppet to close. It features unique balanced construction, allowing predictable switching even under high pressures of up to 5000 psi (350 bar) at both port 1 and port 2. The valve is hydraulically balanced between these ports while maintaining complete sealing from ports 3 and 4, ensuring minimal leakage of less than 10 drops per minute at maximum pressure. The valve opens when pilot pressure drops below 145 psi (10 bar), making it suitable for applications requiring reliable pressure regulation. The DOJPKDN is constructed to minimize internal binding due to excessive torque or machining variations, thanks to its floating style design. It fits into a T-24A cavity and supports a flow capacity of up to 120 gpm (480 L/min). The valve requires a minimum pilot pressure of 300 psi (20 bar) to shift, with all ports capable of handling pressures up to 5000 psi (350 bar). For installation, the valve's hex size is 1-5/8 inches (41.3 mm), and it requires an installation torque between 350 and 375 lbf-ft (475 - 508 Nm). The adjustment screw has an internal hex size of 5/32 inches (4 mm), while the locknut requires a torque range of 80 - 90 lbf-in (9 -10 Nm). A Viton seal kit is available for maintenance purposes. This product is ideal for applications where controlling high-pressure fluid flow with minimal leakage and reliable switching capabilities are essential.

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.
