The Bosch Rexroth FK16C12-2X/V (R900307164) is a high-quality cartridge valve designed for efficient flow control in hydraulic systems. This screw-in cartridge valve, part of the FK series, is engineered to provide precise throttling and check valve functionality. It allows for controlled flow from port A to B, with the throttle cross-section being adjustable via axial displacement of the throttle bolt. The integrated check valve ensures free flow in the reverse direction, from B to A, maintaining system efficiency and protection. The FK16C12-2X/V is specifically constructed without a housing, allowing it to be directly installed into a hydraulic block, simplifying system integration and saving space. Various adjustment types are available for this model, including a rotary knob, lockable rotary knob with scale, and rotary knob with scale options that offer flexibility for different application requirements. Additionally, users can select from various cracking pressures to meet specific system needs. This model falls under component series X and can withstand a maximum operating pressure of up to several hundred bar while facilitating a maximum flow rate in liters per minute that ensures substantial throughput for diverse applications. The robust design and precision engineering of the Bosch Rexroth FK16C12-2X/V make it suitable for a wide range of industrial applications where reliable flow control is essential. Its capabilities ensure optimal performance in systems requiring accurate modulation of fluid flow and pressure regulation within hydraulic circuits.
Type FK . C1…
Type FK . K… (Cartridge valve)
The valves type FK are throttle check valves. The flow depends on the pressure differential between A and B and on the viscosity of the hydraulic fluid.
The valves mainly consist of adjustment type (1), housing (2), throttle bolt (3) and check valve (4).
The flow is throttled from A to B. The throttle cross-section (5) is adjusted by displacing the throttle bolt (3) in axial direction. For free
flow back from B to A, a check valve (4) is installed.
Type FK . C… (Screw-in cartridge valve)
In principle, the function of these valves corresponds to the function of version "K". However, they are delivered without housing (2) and thus can be screwed into the block directly.
