V46 Series 2-Way Pressure-Actuated Water-Regulating Valves
with Union Fittings
Application
This product is made of a copper alloy, which
contains lead. The product is therefore not to be
used on drinking water.
IMPORTANT: The V46 Series 2-Way
Pressure-Actuated Water-Regulating Valves are
intended to control water flow under normal
equipment operating conditions. Where failure or
malfunction of a V46 valve could lead to an
abnormal operating condition that could cause
personal injury or damage to the equipment or other
property, other devices (limit or safety controls) or
systems (alarm or supervisory) intended to warn of,
or protect against, failure or malfunction of the
V46 valve must be incorporated into and maintained
as part of the control system.
The V46 direct-acting models open on a pressure
increase. The V46 valves with union fittings are
available in 1/2-in. through 1-1/4-in. sizes, and may be
used with standard noncorrosive refrigerants.
Installation
IMPORTANT: If these valves are installed on
equipment that contains hazardous or regulated
materials, such as refrigerants or lubricants, the
installer and user should observe all regulations
governing the handling and containment of those
materials.
IMPORTANT: It is recommended to apply a
nonhardening, pliable sealant (Loctite 567 or
equivalent) to the face of the copper tailpiece to
compensate for slight piping misalignments and
surface imperfections on union ends.
