Produced for both refrigerant systems as well as saltwater applications, the V46 series from Johnson Controls features numerous benefits. This series was designed to be “direct-acting” with quick open option on increased pressure, and “reverse-acting” to close on pressure increase. These devices control water flow to a condenser by sensing the changes in pressure through a refrigerant cycle.
The valve design is pressure balanced so that the setpoint
is separate from the water inlet pressure.
These include pressure resistant bellows where refrigerant pressure
grows up to 28-bar. Likewise, the V46 series is
pressure-actuated for fast and direct variations in pressure. They offer a high
flow capacity with their smaller dimensions, in both angled body types and
straight line, available in 3/8”, ½” and ¾” for a high Kv value.

Other features include:
Reduced Hysteresis: The close fitting and sliding parts are within water passages.
Easily Disassembled/Replaced: Valve is designed for easy repairs “in line”.
Durability: bodies and monel parts are made of special
bronze, excellent for sea water applications.
Power Elements: Some
models include stainless steel bellows for applications with ammonia filled
equipment.
Connection Styles Options:
A wide range of types to meet various requirements.
Nickel Plated Seats:
available on valve sizes of 3/8", ½" and ¾” openings, they offer
resistance against corrosion, cavitation and erosion.
Control Action: Direct or reverse action can be factory changed to suit your application.
JCI notes that all of the V46 series regulating valves were
designed as operating devices only. In
several applications where valve failure might result in personal injury or
loss of property, it is required to install a separate safety shut off
valve.
