Is a non-return valve necessary?
Non-return valves are used in systems where it is desirable to make sure fluids flow mostly in one direction, but may not be critical, for example in pumped systems such as heating circuits.
Do non return valves restrict flow?
Do non-return valves restrict flow? Most non-return valves do restrict flow but the amount depends on the type of non-return valve. Swing type wafer non-return valves have a reduced bore, so these will restrict the flow somewhat.
Which is applicable to the non-return valve?
A non-return valve, also known as a check valve, clack valve, one-way valve or retention valve, is designed to allow fluid to flow in one direction only, therefore preventing the liquid or gas from flowing back upstream of the valve.
Where is fuel pump check valve located?
Check Valve: The valve, usually located at the top of the fuel pump, holds the pressure after the engine is shut off so the engine starts quickly the next time you go to start your vehicle.
What is the difference between a non-return valve and a check valve?
A non-return valve lets the fluid flow in one direction. When fluid in the line reverses direction, a check valve prevents backflow by allowing flow in one direction. The check valves are usually designed for a particular pressure.
Do non return valves reduce pressure?
Non-return valves can be fitted with mechanical inhibitors that help reduce the effect but this would generally include either a pressure relief valve or a surge tank.
What is the difference between check valve and a non-return valve?
What is the difference between check valve and non-return valve?

What is inline check valve?
Inline check valves utilize a check mechanism that functions in the fluid line or media pathway of a process piping system. Oftentimes, these check valves are of a compact design allowing for space saving and/or ease of installation into an existing system.
How does a fuel line check valve work?
A check valve is a device that only allows the flow of fluids in one direction. They have two ports, one as an inlet for the media and one as the output for the media. Since they only allow media flow in one direction, they are commonly referred to as ‘one way valves’ or ‘non return valves.
