The Sun Hydraulics DKFPCBN (DKFPCBN) is a high-performance, normally closed, balanced poppet switching element designed for advanced hydraulic systems requiring reliable control under high pressure conditions. This valve operates with a unique balanced construction that ensures predictable switching and efficient performance with 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 when pilot pressure at port 3 surpasses the preset valve setting. The DKFPCBN is engineered to maintain very low leakage rates, typically less than 10 drops per minute at 5000 psi, ensuring minimal fluid loss and enhanced system efficiency. Each of the ports can withstand pressures up to 5000 psi, providing versatile connectivity options within hydraulic circuits. Additionally, the valve's design incorporates Sun's floating style construction which minimizes potential internal part binding due to installation torque or variations in cavity/cartridge machining. This model also offers robust sealing capabilities between its ports; ports 1 and 2 are fully isolated from ports 3 and 4, which are positively sealed. The reseating of the valve occurs when pilot pressure decreases to approximately 85% of the cracking value, enhancing the operational reliability. Designed for ease of installation and maintenance, it features a standardized T22A cavity and adheres to Series 2 specifications with a maximum flow capacity of 30 gpm (120 L/min). The DKFPCBN model is an ideal choice for applications requiring precise control over hydraulic fluid flow in high-pressure environments.

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.
