Viotn Lined Wafer Check Valve

Overview

Check valves are two-port valves, meaning they have two openings in the body, one for fluid to enter and the other for fluid to leave. There are various types of check valves used in a wide variety of applications. Check valves are often part of common household items. Although they are available in a wide range of sizes and costs, check valves generally are very small, simple, or inexpensive. Check valves work automatically and most are not controlled by a person or any external control; accordingly, most do not have any valve handle or stem. The bodies (external shells) of most check valves are made of plastic or metal.The main function water hammer pressure is small, the valve clack stroke is short, the valve clack is light, the spring-assisted closing is provided, and the valve closing speed is fast. The structure length is short, the volume is small, the weight is light, the installation, the transportation, the storage of the valve and the arrangement of the pipeline are greatly facilitated, the material can be saved in a large amount, and the manufacturing cost is reduced.
