The Features and Performance of Butterfly Valve
Jan 18,2023Read More
The check valve is generally installed in the discharge pipeline of the pumping system to ensure that the medium conveyed by the pump does not flow back. With so many check valves on the market, finding the right one for your application can be a challenge. Before you start shopping for a check valve, make sure you know the answers to these five questions.
The purpose of the valve and the environment in which it is used are critical in order to select the correct valve for your specific application. It is very common to install the wrong check valve in the pipeline system, and the check valve is generally selected according to the size of the pipeline.
Knowing the flow rate is most important, in gallons per minute (GPM), gallons per hour (GPH), if your process uses a flow rate higher than 8 feet per second through the valve, there will be higher wear Rate. At flow rates above 8 feet per second, whether it's a rubber valve or a metal valve, wear can cause performance degradation. The faster the flow, the more wear and tear on the check valve, resulting in a shortened life. Knowing the flow rate can help you choose the check valves types that best suits your specific requirements. MstnLand is a professional check valves exporter which provides many kinds of check valves.
Knowing the inlet pressure will help determine which type of check valve you need. Do you need a "ball" style check valve? Do you need a "swing" check valve? Or do you need a silenced check valve? Or a flanged check valve or a wafer check valve? Determining which check valve you need depends on the location of the check valve in the pump system.
Back pressure is the pressure difference between the inlet and outlet pressures. For example, a valve is installed at the end of a pipe that discharges fluid into a small bore. How high will the water be above the water surface when the flow rises? Back pressure occurs when water rises above this valve. Therefore, depending on your detailed usage, you should know how much back pressure the check valve needs to accept.
If the valve is installed submerged in the medium, this means that there is always back pressure on the valve. In this case, you need to pick a check valve that is made of the correct material for submerged conditions, and if you have frequent problems with your check valve, it may be caused by a poor selection. Before purchasing a check valve, please inform the salesman of MSTN International Technologies Company in detail about your working conditions and needs, and you can choose a more suitable valve!
