V46 and V47
Repair Parts and Service Instructions
Applications
The V46 pressure-actuated and V47 temperature-actuated water-regulating valves are used for water-cooled
condensers, bypass service on refrigeration systems, engine cooling, and various industrial applications.
IMPORTANT: The V46 and V47 valves are intended to control liquid flow under normal operating conditions.
Where failure or malfunction of the V46 and V47 valves 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 and V47 valves.
Installation Guidelines
Follow these guidelines to install the V46 and V47 valves.
•
Flush liquid lines to remove filings, chips, and other foreign matter before connecting to the valve.
•
Make liquid line connections so the flow through the valve is in the direction of the arrow on the body casting.
•
Make sure that the bulb and capillary do not rub against any metal obstruction that can wear and damage the
element.
•
Tighten the connector and seal, if furnished with the closed tank connector by tightening the small gland nut on
heavy tubing near the bulb.
•
Avoid mounting the valve where the bulb might be partly above operating liquid level or surrounded by an air
pocket.
•
Mount the valve vertically with the bellows facing downward.
This product is made of a copper alloy, which contains lead. The product is therefore not to be used on drinking
water.
Risk of Environmental Damage
Avoid sharp bends in the capillary tubes. Sharp bends can weaken or kink capillary tubes, which may result in
refrigerant leaks or restrictions of flow.

Adjustments To raise the valve opening point on direct-acting valves, turn the adjusting screw counterclockwise. To lower the valve opening point, turn the range adjusting screw clockwise. See Figure 2. The closing point of the valve is not adjustable. Pressure-actuated valves close approximately 3 to 7 psi (21 to 48 kPa) below the opening point, and temperature-actuated valves close approximately 3 to 5°F (1.7 to 2.8°C) below the opening point. - Page 3 No te : Parts supplied in the renewal kit replace both V46 and V47 Series valve assemblies.

Do not remove the bulb from the ice water until the element is ready to be reinstalled. Otherwise, the pressure increases in the sensing element, resulting in a valve that is hard to reassemble.
