I need to know if anyone knows anything about this valve. It's a Revalco and the info on the plate is as follows:
DN 100 - 25 PB 25
St.35.8 / Rst.37-2
It's leaking at the stem seal. I have a repair kit which is basically a new gland with a couple of o-rings in it. I need to know if the valve has a backseat so I can repair it on the fly. It's the discharge valve on one of my screws and since we use the valve minimization technique around here there are no other valves I can close to isolate it from interstage pressure. Can't find any documentation on it and the Kit came without instructions.
My plan is to coat the stem with clean refrigeration oil and slide on the new gland. Is that correct or should some sort of grease be used on the o-rings instead?
Thanks if you can help.
