CAUTION
Operating Instructions for Needle Valve
1. When shipped from the factory, the needle valve is in the closed position.
2. To operate the needle valve, insert a flat-head screwdriver into the slot on the top
of the needle valve and:
- Open Valve: slowly turn counterclockwise. (Do not continue turning the needle
valve past the point at which the snap ring contacts the bottom of the gland case.)
See the table below to determine the amount of steam discharge
- Close Valve: slowly turn clockwise. (Do not continue turning the needle valve
past the point at which it stops.)
3. If steam should leak from the gland retainer nut or gland case, it can be stopped
by further tightening the gland retainer nut. (Do not over tighten, otherwise the
needle valve may seize and become unworkable.)
