The Johnson Controls V48AE-8 is designed as a 3-way pressure-actuated water regulating valve, specifically for use in condenser water regulation systems associated with cooling towers. This valve is compatible with R-22 refrigerants, providing adaptability for various cooling needs.

With a pipe size of 1-1/4 inches NPT, the valve facilitates substantial flow rates necessary for effective water management. The operating pressure range is set at 145 psig for initiating the opening and reaches up to 190 psig when fully opened, allowing for controlled regulation in high-demand scenarios. A notable feature of the V48AE-8 is its inclusion of a standard capillary length of 30 inches, with the option for an extended 48-inch length if required. The pressure connection style is categorized as Style 45, ensuring ease of integration into existing systems.

The materials used in the V48AE-8 exemplify durability and corrosion resistance, with wetted parts made from aluminum bronze. The valve body itself is fabricated from cast iron, which incorporates brass for internal components, ensuring both strength and resilience. The valve can withstand a maximum water supply pressure of 145 psi and operates efficiently at temperatures ranging from -20°C to 90°C. Additionally, it accommodates a maximum refrigeration overrun pressure of 406 psi, making it suitable for various applications. The diaphragm material is BUNA-N, contributing to the overall reliability of the valve.
