V46 Series Pressure Actuated Water Regulating Valve
Description
The V46 is a pressure actuated modulating valve that is suitable for
use either on closed or open systems. Direct acting valves open on
pressure increase. This type of valve is primarily used to regulate
the flow of water or glycol to a water cooled condenser on a
refrigeration system.
Refer to the V46 Pressure-Actuated Water-Regulating Valve
Product Bulletin (LIT-125687) for important product application
information.
Features
• no close fitting or sliding parts in water passages
• minimizes chatter or water hammer
• free movement of all parts provides smooth pressure
modulation
• refrigerant adjustment is not affected by water pressure
• withstands high hydraulic shock without damage
• range spring does not come in contact with cooling water
• easy manual flushing, if required
• 3/8, 1/2, and 3/4 in. valves may be disassembled and
reassembled without detaching from the refrigeration system or
without pumping down
Applications
This valve is designed to modulate flow of water or glycol to a water
cooled condenser on a refrigeration system.
• ice machines
• computer room air conditioning units
• ice cream machines
• refrigeration cases
