Different types of fluorine lined check valves

check valve There are many types of butterfly check valves, including single disc, double disc, and half disc types. They are classified by caliber and are mainly used to prevent medium from stopping or flowing back, which can reduce the impact force of water. The valve disc of the fluorine lined check valve is disc-shaped and rotates around a shaft. This valve is suitable for large-diameter pipelines. The valve body shape of the silencing check valve is the same as that of the globe valve, so it can be used interchangeably with the globe valve, and its fluid resistance coefficient is also relatively high. Pipeline check valve is a new type of valve with a smaller volume and lighter weight, but its fluid resistance coefficient is slightly higher compared to other check valves. There is another type of compression check valve specifically designed for boiler feedwater and steam shut-off. In addition, there are check valves that are not suitable for installation at the pump outlet, such as spring type, Y-shaped, etc., which will not be introduced one by one here.
