The AqMatic V42C-0032-00000 is a 1-inch normally closed diaphragm valve used in filtration, backwash, and process control systems that require consistent shutoff under pressure.
This configuration includes a cast iron body with brass and stainless internal components and Buna elastomers for the diaphragm, seals, and disc. It is commonly selected for water and non-aggressive fluid applications where durability and serviceability are required.
The valve features a Y-pattern body design that supports higher flow capacity with reduced restriction. For similar configurations and size variations, see the V42 diaphragm valve series.
The valve has 1-inch female NPT connections and is installed in systems where valves cycle under controlled sequencing. Installation guidance, diagrams, and configuration details are available in the V42 valve documentation.
This model does not include a solenoid and is used in systems where pilot pressure is controlled externally. It is commonly paired with AqMatic stagers or solenoid valves depending on system design.
Over time, diaphragm and sealing components will require replacement based on cycle frequency and operating conditions. Compatible repair kits and diaphragms are available for maintenance.
Performance limits, configuration ranges, and system compatibility can be confirmed using the AqMatic technical data.
