| Waterman Stem Covers are designed to protect the stem thread from weather, dirt and damage. Covers are available in steel, stainless steel, aluminum or transparent plastic. Where transparent plastic pipe is used, the gate opening can be determined directly by stem position. Transparent plastic covers have been drilled vent holes to minimize condensation. Stem covers can be used to mount limit switches for PLC feedback or manual lifts. Special “OPEN” and “CLOSED” markings and rule type indicators are usually furnished. |
