V42J-3002-00000 – 3″ – Flanged – Normally Open, Spring Assist Closed

The AqMatic AquaMatic V42J-3002-00000 Diaphragm Valve is a 3-inch, normally open valve with spring assist close functionality, designed for reliable flow control in water treatment and industrial fluid handling systems. Built with a flanged ASTM connection and cast iron body, this valve supports consistent operation in larger pipeline systems where maintaining flow and ensuring dependable shutoff are both critical.

Within the valve assembly, the diaphragm and internal components regulate flow while maintaining proper sealing during operation. The spring assist close configuration adds mechanical closing force to help drive the valve to a fully closed position, improving sealing performance in low or fluctuating pressure conditions. The V42 series y-pattern design features a large seat opening and high lift disc, allowing higher flow rates with reduced pressure loss while supporting smooth diaphragm movement and long-term reliability.
