Description
The Flowserve-Worcester Valve 4446PMSW.100 Ball Valve is a shut off control valve used to start or stop fluid flow in piping circuits in HVAC systems. Its 1‑inch carbon steel ball design provides a straight through flow and positive sealing when rotated, allowing system isolation for maintenance or controlled operation. It is used in hydronic heating, chilled water, or process lines. It works with pumps, sensors, and control tools to support serviceability and safe fluid management. It is applied in system installations where effective on/off flow control is required.
