V46 Pressure-Actuated Water-Regulating Valve Product Bulletin2
Application Overview
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.
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.
