Industrial hydraulic FG/FK throttle and throttle check Valve Screw-in cartridge valve 315Nar
Function and configuration
Type FG . K... and FK . K... (cartridge valve)
The valves of the types FG and FK are throttle and 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),throttling pin (3) and check valve (4) with valve type FK. The flow is throttled from A to B. The throttle cross-section (5) is adjusted by displacing the throttling pin (3) in axial direction. For free flow back from B to A, a check valve (4) is installed with valve type FK.
Type FG . C... and 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.
