Analysis of REXROTH Rexroth throttle valve Z2FS6-5-4X/1QV

Explanation:

Z2FS type valve is a dual one-way throttle valve designed with stacked valve plates. It is used to limit the main oil flow or pilot flow of one or two actuator ports.

Two symmetrically arranged one-way throttling valves can limit flow in one direction while allowing free backflow in the opposite direction.

If it is an oil supply throttle, the hydraulic oil will pass through the throttle point (1) formed by the valve seat (2) and the throttle spool (3), and be introduced into the actuator A? Through channel A. The throttle spool (3) can be adjusted axially by adjusting the screw (4), allowing the throttle point (1) to be adjusted.

The hydraulic oil flowing back from actuator A moves the valve seat (2) relative to the spring (5) in the direction of the throttle valve core (3), allowing the hydraulic oil to flow unobstructed through the one-way valve. Depending on the installation location, throttling effects may occur in fuel supply or emissions.

Mainstream quantity limit (model "2Q")

To adjust the speed of the actuator (main flow limit), a dual one-way throttle valve should be installed between the directional valve and the base plate.

Pilot flow restriction (model "1Q")

By using a pilot operated directional valve, a dual one-way throttle valve can be used to adjust the switching time (pilot flow restriction). In this case, the valve is installed between the pilot control valve and the main valve.
