   What are non-return valves & check valves?

   • Since industrialisation engineers soon realised the need to stop fluids flowing backwards, either to aid processes or to prevent damage. They soon came up with ingenious designs to stop this, giving them a variety of different names amongst them non-return valves (NRVs) and check valves (CVs).

   What is a spring non return check valve?

   • Spring non return valves come with a spring-loaded bearing, which allows fluid to flow downstream but is pushed back to block the inlet if the fluid attempts to flow upstream. What are non-return check valves made of? Non-return check valves are made from a range of different materials with the most popular being stainless steel, brass and PVC.

   What is a non return valve?

   • Non return valves prevent flow from backing up in a piping system. Also called way valves, directional valves are used to manage the direction of an air stream. Shut-off valves are used to open or close flow within a system. Pressure control valves are used to manage actuator force and pressure levels.

   How does a non-return valve work?

   • The non-return valve works based on the pressure difference between the inlet and outlet of the valve. This valve opens when the pressure on the inlet side is higher than that on the outlet side. When the pressure is reversed, the valve closes tightly to prevent reverse flow.

   • What Is The Difference Between A Non-Return Valve and A Check Valve?

   Check valvesare quite ubiquitous in their applications, in that they are found in almost every industrial application, where they act as one-way or non-return valves. Check valves are simple devices in their design. They help to execute an important function in fluid control. Check valves prevent reverse flows, therefore preventing damage and ensur...

   Non-return valves are very important because they function in a unique style. They are an essential feature that helps in a typical retention system to prevent the return of water or reflux that may occur due to pressure loss or a reduction in the supply and flow of water. This helps to provide more excellent safety and precision for thermostatic t...

   We’ve established that both valves are essential and that perform similar functions. In a nutshell, the design of a non-return valve allows it to prevent the backflow or reverse flow of a medium or fluid, and to protect the pump in question from getting damaged due to surge pressures of water hammer following pump shut-down. The check valve, on the...
