Viking VXR Dry Valve Corrosion Resistant High Performance
Shipping calculated at checkout
The Viking VXR Dry Valve installs directly into commercial, industrial, or institutional dry pipe sprinkler system assemblies to control water supply pressure. Operating on a differential valve design, it securely holds back water until heat from a fire opens the mechanical seal, keeping pipes dry to minimize freeze damage risks in cold climates and prevent accidental discharge.
This assembly satisfies life safety demands and complies fully with NFPA 13 national fire protection codes for regulatory adherence.
