22mm Low Pressure Non Return Compression Valve Required

I am trying to locate a 22mm compression fit non-return valve that will open with gravity/tank feed rather than mains. No-one in my local builder's merchants knew there was such a thing and if I look online, the working pressure never seems to be specified.
Any suggestions welcome!

Many thanks,
Garfield

Thanks for the reply.

Sorry I wasn't very clear with my explanation. The valve will be going into the hot water supply to a shower and the hot water is a gravity feed from a tank. I'm told a lot of NRV's require mains pressure to open and so wouldn't be suitable. Does that make more sense?

Many thanks
