It is an understatement to say valves come in a myriad of sizes, materials, and types. While ball valves have the better recognition factor, they are not a homogenous category. They fall into a different type of ball valves including 3-way and check. This article will look at the various types of check valves including the ball and brass check valve.
Check Valves
The purpose of a check valve is to control and/or regulate the direction of the flow of fluids or gases. Pressure activates a check valve. Depending upon the specific application, companies may choose to install any or several of the following available types:
- Ball – the classic example of a check valve
- Diaphragm – utilizes a flexing rubber mechanism
- Disc – more complex
- Split Disc – aka dual plate check valve
- Stop – common for power plants and boiler systems.
- Swing– in household toilet tanks
- Wafer –notable for its small size
All serve the same purpose. However, the material and size can vary significantly. While plastic, PVC, and stainless steel are increasingly common, the traditional metals are bronze and brass. A bronze check valve of any category remains popular for several reasons – many based on the qualities and characteristic of its metal. In applications, past and present, bronze check valves prove to be:
- Durable
- Enduring
- Robust
- High heat resistant
- Freezing temperatures resistant
- Reliable
- Versatile
Such qualities make bronze check valves suitable for use by various companies in the plumbing, oil and gas c and pharmaceutical industries.
Selecting the Right Brass Check Valve
Check valves come in different configurations and materials. The brass check valve is available in different types. Preference for brass swing checks over brass ball check valves will depend upon application, environment, and preference. Consider all possible options for selecting one type over another. It is also possible to arrange for custom valves when the application specifies this to be critical.
