Johnson Controls V43CV-2 Valve

The Johnson Controls V43CV-2 is a heavy-duty, 3-inch pressure actuated water valve designed specifically for demanding marine and industrial condenser applications involving non-corrosive refrigerants. This NAVSEA certified red brass valve features an eight-hole ASME flanged connection, ensuring a secure and leak-proof fit in high-vibration environments. Operating within a 70 to 150 PSI range, it utilizes an internal sweat pressure connection to maintain head pressure by modulating water flow through the condenser. This specific model is functionally identical to the V43CV-2C. Built for longevity in maritime settings, the red brass construction provides superior resistance to de-zincification and stress corrosion cracking. For technicians managing large-scale chiller systems or naval refrigeration plants, the V43CV-2 offers the precise mechanical modulation required to stabilize system pressures under varying load conditions without the need for external power sources.

• NAVSEA Certified Design: Meets rigorous military specifications for reliability in naval and maritime refrigeration systems.
• Red Brass Construction: High-grade red brass water valve body ensures durability and prevents corrosion in freshwater and non-corrosive fluid loops.
• Internal Sweat Connection: Simplifies installation of pressure sensing lines for precise head pressure control.
• ASME Flanged Interface: Standardized 3-inch eight-hole flange allows for straightforward drop-in replacement in existing piping manifolds.
• Wide Modulation Range: Maintains optimal refrigerant head pressure between 70 and 150 PSI, preventing compressor cycling and high-pressure trips.

What is the difference between the V43CV-2 and the V43CV-2C?
These units are technically identical in performance, materials, and specifications. The "C" suffix often denotes specific packaging or bulk configurations but does not affect the valve's mechanical operation or compatibility.

Can this valve be used with seawater applications?
The V43CV-2 is primarily designed for non-corrosive refrigerants and standard water. For direct seawater applications, always verify if a 90/10 Cupro-Nickel alloy version is required by the specific naval contract or environment.

What are the mounting requirements for a 3-inch flanged valve?
The valve features a standard 3-inch ASME flanged pattern. Ensure that companion flanges are aligned and that the internal sweat pressure connection is piped to the high side of the refrigeration system for proper actuation.
