Z2S16 check valve

Z2S16-30 superimposed one-way hydraulic control valve, The superimposed hydraulically controlled one-way valve is a hydraulic component produced by Rexroth. The following is a detailed introduction:

Structural features:

-  superimposed design：the superimposed valve plate design can be easily installed with other hydraulic components to form various hydraulic circuits, which greatly saves installation space and makes the hydraulic system more compact.

Specification parameter: 

- NG：16，it is fit for the hydraulic system of medium to high flow rates.

-Working pressure：it may reach 315 bar，can meet working requirements of most high pressure hydraulic system.

- Flow：300 L/min，can work stably in large flow systems to ensure efficient operation of the hydraulic system.

Z2S type check valve is a superimposed hydraulic control check valve, it can be used to close one or two working oil ports, no leakage for a long time, good stability, free flow of oil from A to A1 or B to B1, Reverse is blocked. If the oil flow through the valve, eg from A to the pressure oil acts on the valve core (1), the valve moves to the right and pushes the ball (2) off the valve seat. A1, when the one-way valve (3) is opened by the controlled oil, the oil can flow from B1 to B. The pressure is unloaded in the B1 cavity, and the one-way valve (3) is fully opened.
In order to ensure that the two one-way valves can be closed reliably when the reversing valve is in the neutral position, the A and B ports of the valve are connected to the oil return line.
