V148 Series Three-Way Pressure-Actuated Water- Regulating Valves Description The V148 Series Three-Way Pressure-Actuated Water-Regulating Valves regulate water flow to control refrigerant head pressure in systems with single or multiple water-cooled condensers. The V148 valves are designed for applications with system water pressures of up to 350 psi (24.1 bar), such as high-rise buildings. V148EK and V148AL valves have an adjustable opening point in a refrigerant pressure range of 145 to 190 psi (10.0 to 13.1 bar). V148EK and V148AL valves are available in 3/4 in. and 1 in. sizes. Use these valves with standard, non-corrosive refrigerants. V148GK1 and V148GL1 valves have an adjustable opening point in a refrigerant pressure range of 200 to 400 psi (13.8 to 27.6 bar). The V148GK1 and V148GL1 Valves are available in 3/4 in. and 1 in. sizes for use with standard, non-corrosive, high-pressure refrigerants. Refer to the V148 Series 3-Way Pressure-Actuated Water-Regulating Valves Product Bulletin (LIT-121712) for important product application information. Features • No close-fitting or sliding parts in water passages • High water pressure design • Pressure-balanced design • Corrosion-resistant material for internal parts • Accessible range spring • Take-apart construction Applications Each application is unique and requires specific engineering data to properly size and design a system to fulfill the appropriate requirements. Typically, a valve is replaced with another valve of the same size in a properly sized and engineered system. Selection To make a rough field estimate of the size of valve for an application, find the valve size by locating a point on a flow chart that satisfies these requirements: • Water flow required by the condenser (Flow) • Refrigerant head pressure rise (P RISE ) • Available water pressure (P AVAIL ) 260
