Throttle Check Valve Type Q QR QV
This is a throttle check valve with a wide variety of mounting types.
The throttle valves Type Q, QR, and QV are valves that control flow. This type comes in five different sizes and is used for flow control in accumulators and control circuits. The throttle type equipped with these types (covering the entire operating range) has higher resistance to degradation of hydraulic oil compared to types with annular gaps (there is no edge filter effect). Type FG allows for fine adjustment and can be used to adjust the switching time of directional control valves, prevent surge pressure, and dampen vibrations, among other applications. The amount of throttle can be adjusted by changing the length of the slot with a screw. These valves are of the "tool-adjustable" type only.
