Siral Zone Valve (ZVW)
Compact and Efficient
ZVW Series zone valves utilize ball valve technology to provide higher flows, higher close-off, and 0% leakage, compared to flapper style or globe style zone valves.
Dip switch selectable fail position and normal position along with unidirectional flow reduces the number of models needed to keep in stock and reduces the opportunity for error in installation.
The valve incorporates a leak-free auto-cleaning ball assembly. Internal leakage in a valve causes energy waste. Most 3-way valves in the industry usually have some level of internal leakage even when new. With our unique valve design both our 2-way and 3-way valves are bubble-tight with zero leakage through all ports.
