Johnson Controls Modulating Valves

Overview

The JOHNSON CONTROLS V46AA-1C is a pressure-actuated modulating valve designed to regulate water or glycol flow to water-cooled condensers in refrigeration systems. It operates on a direct-acting principle, opening in response to pressure increase, and is suitable for both open and closed systems. Built with take-apart construction and an accessible range spring, the V46AA-1C is sized for 3/8-inch connections and is manufactured in the United States. Licensed refrigeration technicians and HVAC-R service pros are the primary installers of this valve. This valve is primarily applied in refrigeration systems where precise condenser water flow regulation is required. Its modulating action allows it to respond to system pressure changes, making it well suited for water-cooled condensers in commercial refrigeration and HVAC-R applications. The copper construction resists corrosion in water and glycol circuits, extending service life in demanding environments. Key Features Direct-acting design opens on pressure increase for responsive flow modulation Compatible with both open and closed water or glycol systems No close-fitting or sliding parts in water passages, reducing wear and maintenance concerns Accessible range spring simplifies field adjustment Take-apart construction allows for in-field service and inspection Copper construction for corrosion resistance in water and glycol circuits Compatibility Designed as an OEM-style replacement or new-installation pressure-actuated…
