Y65F42-0 Johnson Controls Transformer

Overview

The Johnson Controls V46AS-1C is a commercial, two-way pressure-actuated water-regulating valve designed to modulate the flow of water or glycol to water-cooled condensers in refrigeration systems. As a direct-acting valve, it opens automatically upon a refrigerant pressure increase, delivering a fast response to pressure variations to help maintain stable operating conditions.

Features

• Pressure-balanced design ensures the setpoint remains consistent against gradual or sudden water pressure changes
• Built with no close-fitting or sliding parts in water passages to prevent hysteresis or a stuck valve caused by contamination
• Engineered to minimize chatter and water hammer while providing smooth pressure modulation
• Features high refrigerant pressure-resistant bellows that can withstand high overpressure without damage
• Designed to allow for easy manual flushing if required

Specifications

• Nominal Pipe Size: 2 inches
• Inlet and Outlet Connection: ASME Flanged
• Pressure Adjustment Range: 70 to 170 psi (483 to 1,172 kPa)
• Body Material: Cast iron with a special rust-resisting finish
• Compatible Refrigerants: Commercial non-corrosive refrigerants such as R-12 and R-500
• Maximum Water Temperature: 170 deg F (77 deg C)

Applications

• Water-cooled condensers on commercial refrigeration systems
• Ice machines
• Computer room air conditioning units
• Ice cream machines
• Refrigeration cases
