The AqMatic AquaMatic V42K-3032-00000 Diaphragm Valve is a 4-inch, normally closed, spring assist close valve designed for reliable flow control in water treatment and industrial fluid handling systems. Built with a flanged ASTM connection and Buna-N diaphragm and seals, this valve provides consistent shutoff performance in applications where pressure conditions may fluctuate.
The V42 series valve utilizes a y-pattern design with a large seat opening and high lift disc, allowing for higher flow rates with lower pressure loss compared to conventional diaphragm valves. Within the valve assembly, separate flow and control chambers protect internal components while enabling dependable diaphragm movement and positive sealing. The spring assist close configuration adds mechanical closing force to improve shutoff reliability, particularly in low-pressure or variable system conditions. Designed for durability and serviceability, the V42K-3032-00000 valve can be maintained in-line, making it a practical solution for long-term system performance.
