The V46 direct-acting models open on an increase in pressure. Use models A, B, and C typically to regulate water-cooled condensers, and use the low flow D model typically in ice machines.
Commercial V46 valves are available in 3/8 in. to 2 1/2 in. sizes. You can use commercial all-range models from 3/8 in. to 1 1/2 in. with standard noncorrosive refrigerants.
V46 Series valves also come in models for Navy or maritime salt water applications. These valve bodies are of bronze construction, and any metal parts that come into contact with salt water are of nickel copper MONEL construction, which withstands the corrosive action of salt water.
Important: The V46 pressure-actuated
water-regulating valve is intended to control water flow under normal operating
conditions. Where failure or malfunction of the V46 valve could lead to personal injury
or property damage to the controlled equipment or other property, additional precautions
must be designed into the control system. Incorporate and maintain other devices, such
as supervisory or alarm systems or safety or limit controls, intended to warn of or
protect against failure or malfunction of the V46 valve.
