V46AA-1C Johnson Controls Water Regulating Valve

Overview

The Johnson Controls V46AA-1C is a commercial-type, pressure-actuated water regulating valve designed to modulate the flow of water or glycol in response to pressure changes in a refrigeration system. This direct-acting valve opens on a pressure increase, making it ideal for regulating refrigerant head pressure in water-cooled condensers to ensure stable equipment operation.

Features

• No close-fitting or sliding parts in water passages, minimizing the risk of chatter or water hammer
• Built with corrosion-resistant brass body materials for components in direct contact with water
• Features a free-movement design that provides smooth pressure modulation
• Equipped with an accessible range spring that allows for easy manual flushing when necessary
• Designed with a take-apart construction that enables the interior to be disassembled and reassembled without detaching the valve from the refrigeration system or pumping it down
