The Johnson Controls V46BB-2C MARITIME Water REG Valve; 70/260PS1 34 30″ MTG. BRKT. NONE. MTG. BRKT. NONE.
The V46 direct-acting models open on an increase in pressure. Models A, B, and C are typically used for regulating water-cooled condensers, while the low flow “D” model is generally used in ice machines. The reverse-acting V46N valve model closes on an increase in pressure and is typically used for bypass service on refrigeration systems and heat pumps that control water temperature. Commercial V46 valves are available in 3/8 in. through 2-1/2 in. sizes. Commercial all range models (3/8 through 1-1/2 in.), may be used with standard non-corrosive refrigerants, or ammonia refrigerant applications, depending on the model. V46 series valves also come in models designed for Navy or maritime salt water applications. These valve bodies are constructed of bronze, and any metal parts that come into contact with salt water are constructed of nickel copper (monel), which withstands the corrosive action of salt water.
