The Sun Hydraulics FPHKEEV2B12V (Material Number: FPHKEEV2B12V) is a versatile pilot-operated, normally closed, electroproportional throttle valve with a reverse free flow check. This advanced valve is designed to provide precise control over fluid flow and pressure in hydraulic systems. When the coil is energized, it creates an opening force on the pilot stage, which vents the main stage poppet to open proportionally. It allows metered flow from port 1 to port 2 while enabling reverse free flow from port 2 to port 1. The valve can handle pressures up to 5000 psi and features interchangeable coils that are compatible with other solenoid-operated valves from Sun Hydraulics. For superior performance, it's recommended to use an amplifier with current sensing and adjustable dither settings between 100 and 250 Hz. The valve incorporates Sun's floating style construction, reducing the risk of internal parts binding due to excessive torque or machining variations. It offers several manual override options, including a momentary-twist override that allows manual operation by twisting the override clockwise by 90 degrees. The FPHKEEV2B12V fits into a T16A cavity and belongs to Series 3 with a capacity of up to 60 gpm (240 L/min). The maximum valve leakage at high viscosity is minimal at just 10 drops/min at 5000 psi. For installation, it requires a torque range of 150-160 lbf ft (203-217 Nm), and its compact design weighs only 1.50 lb without the coil or up to 2.00 lb with it included. The product comes equipped with Viton seal kits for both cartridge and coil applications, ensuring reliable sealing performance in various operating conditions.
