Brass Check Valves

What are the 5 types of check valves?

There are five types of check valves, each with its own advantages and disadvantages. It's important to choose the right type for your application, so be sure to read up on all the options available before making a purchase.

Which check valve is best?

A swing check valve is the most common type of check valve and they are economical to operate. They have a simple flow direction selection mechanism that makes them ideal for many applications.

There is no external power required, making them the perfect choice for many applications

Can a brass check valve be installed vertically?

Brass check valves can be installed vertically in a number of locations, depending on your needs. The size and shape of the valve will depend on the type of application you are installing it for.

You will need to find an approved installer to install the brass check valve correctly.

What is the difference between check valve and backflow preventer?

A check valve is used to restrict water flow and a backflow preventer is used to keep water from coming back into the system. Check valves usually have a hinged plug that allows water to pass through the pipeline, but blocking it from returning.

Backflow preventers apply increased pressure on a pipe in order to ensure that water can only flow one way

Is a swing or spring check valve better?

A spring-loaded check valve is designed to reduce the effects of water hammer, while a swing check valve may exacerbate the issue. It is important to choose the correct type of valve for your application in order to minimize potential problems.

Compare different types of valves and decide which one will best suit your needs

What are the three different types of check valves?

Ball and piston check valves are used to control the flow of liquid by allowing or preventing a fluid from flowing through a hole in a closed position. Stop check valves are typically found on water lines and can be opened if necessary to shut off water supply completely.

Check valves come in various types, sizes and designs depending on their specific application

What is the difference between check valve and stop check valve?

A stop check valve is a type of valve that helps to regulate the flow of water. They are basically check valves that have an override control to stop flow regardless of pressure or direction.

When installed correctly, a stop check valve will help prevent damage in your pipes

How do you size a check valve?

When sizing a check valve, you must have the viscosity of material, media, pressure, and temperature to be able to customize the centre-guided valve to the specific application.

Check valves can be customized with or without an annular groove on the body depending on how much sealing action is required between two surfaces. To size a check valve correctly, you must have all of these factors at hand

Are two check valves better than one?

When you have a two-check valve system, you'll need to replace the pump when it breaks. Having a second check valve can cause water hammer and possible contamination.

If one of your valves fails, you may experience higher than normal pressure

What is difference between swing type and wafer type check valve?

Swing check valves restrict flow by a greater percentage than wafer type check valves, fitting into small spaces between flanges and designed for use in tight spaces.

Wafer type check valves are restricted by less of a percentage, making them easier to open and fit into larger areas. The swing valve is better suited for high-pressure applications while the wafer valve is more versatile for lower pressure needs

How reliable are check valves?

Check valves are susceptible to failure and require regular maintenance in order to remain operational. Detection of a failed valve is rare, so it may go undetected for years unless something goes wrong.

Maintenance and repair of check valves requires special skills and tools, so failures are not common but should be taken seriously nonetheless

Should check valve be horizontal or vertical?

A horizontal line is often considered the more aesthetically pleasing option, but it does come with some benefits. Vertical lines are less expensive and easier to manage, making them a good choice for smaller homes or apartments.

It ultimately depends on your specific needs which type of check valve to choose for your vessel

Do swing check valves leak?

Swing check valves are often used to prevent reverse flow of fluids or gases, and can fail if not properly adjusted. Check valves may leak when the hinged disc falls out of adjustment, pressure and loss of fluid can result from a broken seal in the valve body, swinging disks may fall out of adjustment causing leaks, and lastly swing check valves can be prone to failure if not regularly inspected for proper function.
