Direct acting relief valve YF15-01 hydraulic cartridge valve

1. The internal core components of the throttle valve, that is, the stem spool is combined into the opening and closing parts of the throttle valve, and the core head is mostly conical and streamlined, through which the size of the cross-sectional area of the pipeline is changed to adjust the flow rate and pressure of the pipeline. At present, there are many structural forms of opening and closing parts, and their structural forms are also different.
2, the throttle valve is a valve that can also control the fluid flow by changing the length of the throttle. If the throttle valve and the check valve are connected in parallel, it can be combined into a one-way throttle valve, and the combination of it and the two-way valve is a two-way throttle valve; The combination of throttle valve and relief valve can also form a throttling speed regulation system. In short, different occasions use different forms of combination.
3, for example, the throttle valve in the combination of the above three kinds of valves, applied in the system speed control of the quantitative pump hydraulic system, that is, the oil path throttling, the return oil path throttling and the bypass throttling three kinds of speed control systems. Because the throttle valve has no negative flow feedback function, it will not be unstable due to load changes, so it is mostly used in situations where the load changes little, or the speed stability is not required.
