V46DA-2C Johnson Controls Water Regulating Valve

Overview

The Johnson Controls V46DA-2C is a commercial-type, 2-way pressure-actuated water regulating valve designed to modulate the flow of water or glycol in response to changes in refrigerant pressure. This low-flow, direct-acting model opens on a pressure increase to maintain stable head pressure in water-cooled systems.

Features

• Direct-acting operation that opens on a pressure increase
• Eliminates close-fitting or sliding parts in water passages to minimize chatter and water hammer
• Take-apart construction allowing interior access without removing the valve from the system or pumping it down
• Corrosion-resistant material for parts coming into direct contact with water
• Pressure-balanced design to maintain consistent setpoints during water pressure fluctuations
• Accessible range spring for easy manual flushing

Specifications

• Pipe Connection: 3/8 inch NPT threaded inlet and outlet
• Pressure Connection: 1/4 inch female flare nut with a 30-inch capillary
• Opening Point Range: 70 to 260 psi
• Maximum Flow Rate: 2.5 GPM
• Maximum Operating Pressure: 320 psi
• Maximum Water Temperature: 170 degrees Fahrenheit
• Valve Material: Brass body

Applications

• Designed for regulating water or glycol flow to a water-cooled condenser in commercial refrigeration and HVAC environments
• Ideal for low-flow equipment applications, such as ice machines, using non-corrosive refrigerants
