The Sun Hydraulics DKFPCAV (DKFPCAV) is a precision-engineered hydraulic valve designed for high-pressure applications, capable of handling up to 5000 psi (350 bar) at both port 1 and port 2. This normally closed, balanced poppet switching element operates by maintaining the poppet in a closed position until pilot pressure applied at port 3 reaches a pre-set threshold determined by an integral pilot relief stage, subsequently shifting the poppet to an open position. The valve's unique design ensures predictable switching and minimal leakage\u2014typically less than 10 drops per minute at maximum pressure\u2014between ports 1 and 2. Constructed with Sun Hydraulics' floating style, the DKFPCAV minimizes internal part binding that can occur due to excessive installation torque or cavity/cartridge machining variations. It features fully sealed connections between ports to prevent any cross-contamination or leakage. The valve's configuration includes a T22A cavity and belongs to the Series 2 product line, with a flow capacity of up to 30 gpm (120 L/min). Additionally, it requires a minimum pilot pressure of 300 psi (20 bar) to shift the valve. The DKFPCAV is equipped with several technical specifications for installation and maintenance including a valve hex size of 1-1/8 inch (28.6 mm), an installation torque range of 45-50 lbf ft (61-68 Nm), and an adjustment screw internal hex size of 5/32 inch (4 mm). The locknut has a hex size of 9/16 inch (15 mm) and requires a torque setting of between 80-90 lbf in (9-10 Nm). For maintenance or repair, Viton seal kits are available under part number: 990022006. This valve is ideal for applications requiring reliable high-pressure performance and precise fluid control in hydraulic systems.

This is a normally closed, balanced poppet, switching element. When pilot pressure is applied to port 3, the poppet remains closed until the pilot pressure reaches the setting established by the integral pilot relief stage, at which point the poppet shifts to the open 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 open position.
- Any backpressure at the drain port is directly additive to the valve setting.
- Valve will reseat when the pilot pressure falls to 85% of the cracking value.
- 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.
