The Sun Hydraulics DKFPCBV (DKFPCBV) is a high-performance, normally closed, balanced poppet switching element designed for advanced hydraulic systems requiring reliable and precise control. This valve operates with a unique balanced construction that ensures predictable switching at very high pressures up to 5000 psi (350 bar) at both port 1 and port 2. It features an integral pilot relief stage that allows the poppet to shift to the open position only when pilot pressure at port 3 surpasses a pre-set threshold. The valve's design includes fully sealed ports 1 and 2 from ports 3 and 4, ensuring no cross-port leakage, which is typically less than 10 drops/min at maximum pressure settings. Additionally, any backpressure at the drain port directly adds to the valve setting, enhancing its performance under varying conditions. The DKFPCBV will reseat when the pilot pressure drops to 85% of the cracking value, contributing to its efficient operation. Constructed with Sun's floating style construction, the DKFPCBV minimizes internal parts binding which could occur due to excessive installation torque or cavity/cartridge machining variations. It supports a maximum flow capacity of 30 gpm (120 L/min) and requires a minimum pilot pressure of 300 psi (20 bar) to shift the valve. The robust design specifications include an installation torque of between 45-50 lbf\u00b7ft (61-68 Nm), ensuring secure and reliable installation in demanding applications. This valve is particularly suitable for systems where precise hydraulic control is critical and can operate effectively across various hydraulic functions due to its versatile design and high reliability.

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.
