Sorry for the slow response. i was out of town working.
I am using valves from Grainger. They are either chrome plated brass or forged brass
The part number for the 1/2 inch female valve is 1PYN9. This valve is rated for water, oil and gas at 600 PSI and only costs $9.51.

Hi All.
Everything plumbing related that they have in my local store is SCHED 40 including the valves. They are only rated to 220 psi.
So, Im currently using specially ordered Worcester ball valves for variable flood, vent, cabin flood etc
They are the high pressure ones (cant remember the exact rating now) but the trouble is that they are REALLY expensive.
Any suggestions for some cheaper valves as i need to order a load of 1/2 inch ones and i nearly just passed away at the price of the worcester ones.
What sort of valves have other people used?
Thanks
James
