The AqMatic V42B-0000-00031 is a 3/4 inch normally open cast iron diaphragm valve with an independent pressure (IP) solenoid, designed for systems that require consistent 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 valve uses a Y-pattern body with a large seat opening and high-lift diaphragm, supporting higher flow rates with lower pressure loss in smaller-diameter systems.
The valve is configured as normally open, allowing flow under standard conditions and closing when control pressure is applied to the upper diaphragm chamber.
The independent pressure (IP) solenoid (115V / 60Hz, NEMA 1) enables actuation using an external pressure source rather than relying solely on line pressure. This is particularly useful in systems with variable or low line pressure where consistent valve response is required.
This configuration uses a Buna-N diaphragm, seals, and discs, making it suitable for standard water treatment and fluid handling applications. The valve is commonly integrated with stagers and stager controls for automated sequencing, or used alongside other V42 diaphragm valves in multi-valve assemblies.
