Pharma Valves for high pressure

[tigertommy]

I´m looking for a ball or any kind of valve, that should be welded onto a 6mm by 1mm wall, with a trubore of 4mm, and with a max inside surface finish of less than 0,5Ra.
Max working pressure is 100 bar.
Any ideas where to find such valve, the application is HPLC.

I know for a fact that a company called Ball Valves UK do this spec of valve, although I'm not sure about the 4mm bore.

You need their "RP" series valve.

Contact your Worcester distributor. The factory can merge some of the parts/technology from the WK74 clean valve and the H44 high-pressure valve. The WK74 is "rated" at 500 psi(34 bar) but in a 6mm valve it is difficult not to be able to handle much higher pressures. The almost identical H44 goes to 5000 psi (345 bar). I have spoken with the engineers and they did not flinch.
