The 944-026 valve stem stop is a direct replacement component for an extensive range of spray equipment including numerous PowrTwin models (12000GHD, 12000GH, 12000 GHD, 8900GH, 6900GH, 4900GH, 4500, 3500, 3500 50th anniversary), various PowrLiner models (8900, 6000, 5000, 4900, 4000), Hydra M and Hydra Pro 2000_4000, Hydr M nad Hydra Pro Super, Commander, Admiral, and 0528925N_2000_4000 equipment. This component is installed in a valve assembly to limit the travel of the valve stem. By providing a positive stop, it ensures that the valve opens only to the designed position and closes fully, preventing over-travel that could damage internal components or affect flow control. The stop may be an adjustable feature or a fixed component. A properly functioning valve stem stop is essential for accurate valve timing, consistent flow, and preventing internal damage. A worn, damaged, or missing stop can allow the stem to travel too far, causing improper sealing, reduced flow, or mechanical damage. This replacement stop is manufactured to exact specifications for size, shape, and material. Installation requires proper positioning within the valve assembly. Regular inspection during valve service helps identify stops that need replacement.
