YW110-10 and YW116-16 are both hydraulic control check valves, mainly used for flow control and oil pressure control in hydraulic systems. The specific introduction is as follows: 1. YW110-10 valve YW110-10 valve is a kind of one-way valve controlled by hydraulic control, mainly used to control the flow in hydraulic systems. The valve adopts diaphragm structure, which has the characteristics of strong flow capacity, low resistance and reliable operation. At the same time, the valve also has a self-maintaining function, which can be automatically closed when there is no control signal, avoiding the phenomenon of hydraulic oil backflow in the hydraulic system. The valve is commonly used in hydraulic machinery, metallurgical equipment, ships, construction machinery and other fields. 2. YW116-16 valve YW116-16 valve is also a hydraulically controlled one-way valve, which is mainly used to control the oil pressure in hydraulic systems. The valve adopts needle valve structure, with sensitive response speed and precise pressure control ability, which can effectively control the oil pressure in the hydraulic system. At the same time, the valve also has good sealing performance, which can avoid leakage in the hydraulic system. This valve is commonly used in hydraulic machinery, automotive, aviation and other fields.
