| DB20-1-50/31.5U/N is a high performance relief valve designed for use in hydraulic systems to precisely control fluid pressure and flow. This model of relief valve combines advanced technology and high-quality materials to ensure stable and reliable performance under various working conditions. |
| Working principle: The overflow valve uses the change of system pressure to automatically adjust the opening and closing of the valve. When the system pressure is lower than the set value, the pilot valve remains closed, and the main valve core is also in a closed state under the action of the spring, and the hydraulic fluid is normally guided to various components of the system. Once the system pressure reaches or exceeds the preset value, the pilot valve opens under the action of the hydraulic pressure, resulting in a pressure difference between the upper and lower parts of the main valve core, which in turn pushes the main valve core upward, opens the main valve port, and the excess hydraulic fluid flows back to the oil tank through this valve port, thereby achieving precise control of the system pressure and preventing equipment damage caused by excessive pressure. |
| Product Features High-precision regulation: Through the precision-machined valve core and spring system, high-precision pressure regulation is achieved to ensure stable system pressure. High reliability: The use of high-quality materials and advanced manufacturing processes ensures that the valve body is sturdy and durable, the valve core and seals are highly wear-resistant, and the service life is extended. Easy to maintain: Reasonable design, compact structure, easy installation and maintenance. At the same time, a variety of connection methods are provided to meet the needs of different application scenarios. Safety protection: When the system pressure exceeds the set value, the overflow valve automatically opens to release excess pressure and protect the system from damage. |
| Applications: Engineering machinery: such as excavators, loaders, cranes, etc., used to control the working pressure and flow of hydraulic systems. Metallurgical equipment: such as steel mills, aluminum plants, etc., used to control the hydraulic transmission system in the smelting process. Shipbuilding: such as ship steering gear, anchor winch, etc., used to control the pressure and flow of ship hydraulic systems. Petrochemical: such as refineries, chemical plants, etc., used to control the hydraulic system of chemical equipment. |
