Rexroth Z2FS 6 Double Throttle Check Valve Description This is a used but reliable double throttle check valve, model Z2FS 6-2-44/2QV, from Bosch Rexroth. As a sandwich plate valve of size NG6, it is designed for stacking in hydraulic systems to control the flow rate of fluid to an actuator. It provides meter-in or meter-out control in two ports (A and B) independently, with check valves allowing for free return flow. This component is essential for applications requiring precise speed control of hydraulic cylinders or motors.

FAQ What is the function of the check valves in this Z2FS 6-2-44/2QV? The integrated check valves allow free flow in one direction, bypassing the throttle. This means you can control the speed of an actuator (like a cylinder) in one direction (e.g., extending) while allowing it to retract at full speed. What does “NG6” signify for this hydraulic valve? NG6 refers to the nominal size of the valve and its mounting pattern, also known as CETOP 3. It defines the port locations and dimensions, ensuring interchangeability with other NG6 subplates and valves from various manufacturers. The model code ends in “/2QV”. What do these letters mean? The “2Q” indicates the type of adjustment element, which is a two-stepped throttle knob for setting the flow. The “V” specifies the seal material, which is FKM (also known as Viton), suitable for a wide range of hydraulic fluids and higher temperatures.
