AquaMatic V42G-0000-00031 – 2 Inch Normally Open – IP Solenoid – BUNA N

The AqMatic V42G-0000-00031 is a 2-inch normally open cast iron diaphragm valve with an independent pressure (IP) solenoid, designed for high-flow systems that require controlled pilot actuation using an external pressure source.

This model is part of the V42 series, a metal-body diaphragm valve platform used across water treatment, filtration, and industrial flow control systems. The V42 design uses a Y-pattern body with a large seat opening and high-lift diaphragm, allowing higher flow rates with lower pressure loss compared to traditional valve designs.

The V42G body (426-B) is designed for 2-inch systems where higher flow capacity is required, often serving as a mainline valve in filtration or softening applications.

This configuration is normally open, meaning the valve allows flow under standard conditions and closes when control pressure is applied. The independent pressure (IP) solenoid enables actuation using an external pressure source, making it suitable for systems where line pressure alone is not sufficient or consistent.

The valve is built with a Buna-N diaphragm and sealing components, supporting compatibility with standard water treatment and fluid handling applications. It is commonly integrated with stagers and stager controls for automated sequencing, or used alongside other V42 diaphragm valves in multi-valve assemblies.
