Any vacuum valve will do really, you're still in the "dirty" or relatively low vacuum with the roughing pump.

However, it's been a while since I originally posted that diagram and since have been advised that ball valves won't hold up to vacuum scrutiny - they might be applicable in the fore line, but I've been strongly advised not to use them in the high vacuum line. Most angle valves from MDC, Lesker, Pfeiffer etc. are rated for UHV or at least HV so they're sealed for Fusor vacuums anyways.

Hope that helps,
Tom
