Title: N2 regulator. What PSI?
Post by: FriendlyFinger on October 05, 2002, 03:22:00 AM

Hi there,

I'm about to buy a single stage high purity N2 regulator for general work, eg; Grignard, solvent blanketing etc. But I'm not sure about what outlet psi to choose. So far I'm thinking low pressure 2-15 psi with a neele valve for fine control.

Will I be ham strung with a low pressure unit. Isn't 15 psi enough for most jobs?

thanks,
regards,
FF.

Should do it man.

Might not fit the bill for hydrogenation, but I think that requires a different regulator anyway.

Hey,

A needle valve is nice and controllable for low pressure requirements.  Obviously high pressure hydrog's will require more, but will you REALLY be doing high pressure hydrog's ?  One word of advice, you should NEVER store a needle valve fully closed, always open it slightly, they are SO prone to jamming otherwise.

PS....thats stupid of me to say anyway, since hydrogen regulators are engineered so they have the OPPOSITE threading to other regulators...you need a specific regulator for a hyrdogen cylinder. Sorry 'bout that, too much wine im afraid (hiccup).
