Operating Instructions for Needle Valve Unit
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)
