V46 Series Pressure-Actuated Water-Regulating Valves

The V46 pressure-actuated modulating valves come in
two types of control action: direct acting or reverse

acting. Direct-acting V46 valves are typically used for
regulating refrigerant head pressure in water-cooled

condensers. Reverse-acting V46N valves are typically
used for bypass service on refrigeration systems and

heat pump applications. Commercial V46 valves may
be used with standard non-corrosive refrigerants.

Features and Benefits

No Close Fitting or Sliding
Parts in Water Passages -
Provides robust control in less than ideal

Corrosion Resistant Material
for Parts that Come in Direct
Contact with Water -
Promotes longer valve life

Accessible Range Spring - Allows easy manual flushing, if required

Take-apart Construction Interior of valves accessible without removing
valve from refrigeration system or pumping down

Pressure-balanced Design Valve maintains consistent setpoint against both
gradual and sudden water pressure changes

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: All V46 Series water regulating
valves are designed for use only
as operating devices. Where

system closure, improper flow, or
loss of pressure due to valve
failure can result in personal
injury and/or loss of property, a

separate pressure relief or safety

shutoff valve, as applicable, must

be added by the user.
