V43/V243 Series Pressure-Actuated Water- Regulating Valves Description The V43/V243 Pressure-Actuated Water Regulating Valves regulate water flow through the condenser of large refrigerated cooling systems. These pilot- operated valves open on an increase in refrigerant head pressure and provide modulating operation. The V43/V243 water regulating valves are available for commercial and maritime applications. V43 valves are available for noncorrosive low- and medium-pressure refrigerants such as R-134A, R-404A, R-502, and R-507. V243 valves are available for noncorrosive high- pressure refrigerants such as R410A. Commercial V43/V243 valves feature a cast iron body, brass internal parts, and bronze seat material. To resist the corrosive action of sea water, the V43/V243 maritime and Navy models feature a red brass body, bronze and MONEL ® interior parts, and MONEL seat material. Refer to the V43/V243 Pressure-Actuated Water Regulating Valves Product/Technical Bulletin (LIT-125683) for important product information.
