Johnson Controls V48AE-8 Regulating Valve

The Johnson Controls V48AE-8 Regulating Valve is a high-performance 3-way water regulating valve specifically engineered for HVACR condenser systems utilizing atmospheric or forced-draft cooling towers. This 1-1/4 inch NPT threaded valve features a pressure-balanced design, utilizing rubber sealing diaphragms to offset water pressure fluctuations and prevent sedimentation or corrosion of internal components. With a precise 145-190 PSI range and a 30-inch Style 45 capillary, the V48AE-8 ensures efficient head pressure control by modulating water flow between the condenser and the bypass line.

For technicians and contractors, this Penn V48 Series valve provides a robust solution for maintaining refrigerant stability in single or multiple condenser hook-ups. The direct-acting mechanism opens Port 1 to Port 2 on a pressure increase, allowing for rapid response to compressor load changes. Its durable copper alloy construction and field-adjustable range screw make it a versatile pressure-actuated water valve for diverse commercial refrigeration and cooling tower applications.

• System Precision: Maintains optimal head pressure by effectively bypassing water flow to the cooling tower.
• Durable Construction: Pressure-balanced diaphragms protect the range spring and sliding parts from water exposure.
• Versatile Compatibility: Designed for use with standard non-corrosive refrigerants across various condensing units.
• Standardized Fit: Features a 1-1/4" NPT threaded connection and a standard 30" capillary length for seamless integration.

Common Questions

How do you adjust the opening point on the V48AE-8?
The opening point can be field-adjusted by turning the range-adjusting screw located at the top of the spring housing using a standard service wrench or screwdriver.

Can this valve be used for potable water applications?
No, this product is constructed from a copper alloy containing lead and is not intended for use in drinking water systems.

What is the purpose of the 3-way configuration in a cooling tower setup?
The 3-way design allows the valve to bypass water around the condenser during low-load conditions, ensuring the tower operates efficiently without over-cooling the refrigerant.
