Steel Check Valve 3/4 Inch NPT

This BUYERS PRODUCTS HCV075 check valve is a steel component designed for industrial plumbing systems. It allows flow in one direction while preventing backflow in hydraulic or pneumatic lines. The valve suits maintenance engineers and plant operators who need a durable, inline non-return device for fluid control.

Suits 3/4 NPT lines only

This valve fits pipes threaded to 3/4 inch NPT and is built from steel for strength and corrosion resistance. It is not for systems requiring larger or smaller port sizes, different thread standards such as BSP, or plastic-bodied valves for chemical compatibility. Buyers needing a different connection type or material should look at other configurations.

3/4 inch NPT thread size

The single specification that decides fitment is the 3/4 inch NPT thread on both ports. Confirm that your piping matches this exact thread standard before ordering, as mismatched threads will prevent a seal and cause leaks. No other dimension or rating in the data overrides this requirement.

Questions about this item

What NPT thread size must my existing pipe or fitting have to accept this 3/4 In. NPT steel check valve?

The valve has 3/4 In. NPT threads on both ends, so the connecting pipe or fitting must also be 3/4 In. NPT for a proper seal.

Will this check valve operate correctly with the older brass or iron piping already in my system?

Yes, the steel body and NPT threads are compatible with standard brass, iron or steel piping of the same 3/4 In. NPT size.

How can I verify the valve is allowing flow in only one direction after installation?

Pressurise the upstream side; flow should pass through, while applying pressure downstream should show no leakage past the seat.
