Non Return Valves

At Anchor Pumps, we offer an extensive range of non-return valves at affordable prices. All of our non-return valves are made from the highest quality materials, ensuring that we deliver only the best in quality and reliability.

What is a non-return valve?

A non-return valve is a small mechanical tool that fits onto a pipe and ensures that water flows through the pipe in the right direction. Designed to prevent backflow, non-return valves are an excellent addition to a variety of pumping solutions as they save your pump from potential damage in the event of reverse flow.

Non-return valve or check valve?

There are different types of non-return valves. These include:

  • Spring-loaded
  • Swing type
  • Clapper type valves

Non-return valves and check valves are often used interchangeably to describe each of the different valve types.

If you want the engineering definition, a check valve is the spring loaded valve type, and the non-return is the clapper or swing type valve.

In most domestic systems, the difference between the three valve types will bear little relevance to the water system performance.

What is the minimum pressure it will open?

All non-return valves sold here at Anchor Pumps are designed to require a minimum pressure of 0.3 bar to operate. It’s unlikely that you will need a minimum pressure lower than 0.3 bar in most domestic pumping systems. However, if you are suffering from a specific low-pressure problem, please feel free to contact our customer service team who will be happy to help you with your particular situation.

What nut sizes are available?

At Anchor Pumps, we offer a variety of nut sizes to provide a solution for a variety of problems. These include 20mm, 25mm, 32mm, 38mm, 50mm, 65mm, 76mm and 102mm nut sizes.

The Latest Valve Technology

No matter what your current system is, we have a non-return valve that can secure your plumbing system. As well as the wide choice of sizes on offer, we can also guarantee that all our check valves have been specially designed, built and tested to ensure maximum safety, high quality and durability.
