The Sun Hydraulics DOHPLDV (DOHPLDV) is a normally open, balanced poppet switching element designed for high-pressure hydraulic systems. This valve operates by maintaining an open state until the pilot pressure applied to port 3 reaches a specified threshold, at which point it shifts to a closed position. The unique balanced construction ensures predictable switching performance at pressures up to 5000 psi (350 bar) for both port 1 and port 2. The valve is designed to handle backpressure effectively, as any backpressure at the drain port directly adds to the valve setting. It reopens when pilot pressure falls below 145 psi (10 bar). The DOHPLDV is hydraulically balanced between ports 1 and 2, with these ports fully sealed from ports 3 and 4, ensuring positive sealing of ports 3 and 4. It boasts a low leakage rate between ports 1 and 2, typically less than 10 drops per minute at maximum pressure. All ports can manage up to the maximum operating pressure of 5000 psi (350 bar). The design incorporates Sun's floating style construction to minimize potential binding issues due to installation torque or machining variations in cavity or cartridge. This valve fits a T-23A cavity and belongs to Series 3 with a capacity of handling flow rates up to 60 gpm (240 L/min). The minimum pilot pressure required for shifting the valve is set at 300 psi (20 bar). Installation specifications include a valve hex size of 1-1/4 inches (31.8 mm) with an installation torque range of 150-160 lbf ft (203-217 Nm), while adjustment screw internal hex size is specified as 5/32 inches (4 mm). This product includes a Viton seal kit identified by part number: Viton:990023006.

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.
- 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).
- 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.
