The Sun Hydraulics DOFPLWV (Material Number: DOFPLWV) is a normally open, balanced poppet switching element designed for precise hydraulic control applications. It features a unique balanced construction that allows predictable switching at pressures up to 5000 psi (350 bar) at both port 1 and port 2. The valve remains open until the pilot pressure applied to port 3 reaches the setting determined by the integral pilot relief stage, causing the poppet to shift to a closed position. This valve is engineered to handle backpressure at the drain port, which directly adds to the valve setting, and will reopen when pilot pressure drops below 145 psi (10 bar). The DOFPLWV model ensures hydraulic balance between ports 1 and 2 while fully sealing them from ports 3 and 4. Ports are capable of handling pressures up to 5000 psi (350 bar), with an impressively low leakage rate of less than 10 drops per minute at maximum pressure. It incorporates Sun's floating style construction, minimizing risks of internal binding due to installation torque or machining variations. The valve fits into a T22A cavity and belongs to series 2 with a capacity of handling flow rates up to 30 gpm (120 L/min). Key specifications include a minimum pilot pressure requirement of 300 psi (20 bar) for shifting the valve, with control pilot flow detailed in performance data documentation. Installation requires specific torque settings for optimal performance: valve installation torque ranges from 45-50 lbf ft (61-68 Nm), while locknut torque is specified at 80-90 lbf in (9-10 Nm). The adjustment screw has an internal hex size of 5/32 in (4 mm), and it uses Viton seal kits for reliable operation under various conditions.

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.
