Check valves are one of the important valve types that are used widely in many different applications. These are essential components that are installed typically on the end of a pipe or channel and operate as a non-return/one-way valve that tends to open under pressure.

Once the media flowing passes through the check valve, it can travel back through the valve again. Check valves are available in a range of materials, designs and sizes. At Dutco Tennant LLC, high-quality check valves are supplied that are suitable for Oil & Gas application.

In fact, these quality check valves will also be exhibited for this year’s ADIPEC 2022 starting from 31st October 2022. Visitors can catch live product demonstrations and see this valve up close.

But before you witness check valves at the exhibition, here’s a quick list of considerations that you need to keep in mind for selecting the right check valve. Keep reading till the end to find out more.

Application

Understanding about the application for which the check valve service will be used is critical in choosing the suitable check valve. Will it be used to handle corrosive materials? Will the application system discharge points below water? These are some of the obvious conditions that can be overlooked easily when it comes to making a choice for a check valve.

A very common error that is made when selecting a check valve is going with a valve that fits the system but cannot handle the flow conditions or the matter passing through the valve efficiently. Therefore, it is essential to consider all the aspects of application needs when choosing the ideal check valve.

Inlet pressure

With the understanding of inlet pressure, it becomes more helpful to select  which style of check valve is best suited for your requirements. It can allow you to decide whether there is need for an in-line check valve, a flanged style check valve or a slip-on check valve.

The decision of choosing which valve for use will be based on where the check valve will be installed in your pumping system.

Flow rate

Similar to how important it is to know what matter the check valve will be handling – it is also critical to know the flow rate of the medium. Typically, the flow rate is measured in terms of gallons per minute (GPM), gallons per hour (GPH), or litres per second (L/S).

If an application is generating a flow rate more than 8 feet per second flowing through the valve, there is a higher risk that the will succumb to deterioration quickly – regardless of whether a metal-seated valve or rubber-seated valve is used.

Back pressure

Back pressure is basically the differential pressure between the outlet and inlet pressures of the system. It is important to know if a check valve will be able to withstand the back pressure that the valve could be exposed to.
