Johnson Controls V46NE-2 Valve

The Johnson Controls V46NE-2 is a robust 1-1/4 inch NPT pressure actuated water regulating valve designed specifically for high-capacity commercial condenser cooling applications. Engineered with a durable cast iron body, this reverse-acting water valve is optimized for systems utilizing non-corrosive refrigerants. It features an adjustable opening point range of 40 to 100 PSI, allowing technicians to maintain precise head pressure control by modulating water flow in response to refrigerant pressure changes. This model include a 30-inch capillary assembly with a 1/4 inch flare nut (Style 45) pressure element, ensuring reliable feedback for HVACR system efficiency. The V46NE-2 is a direct replacement for the V46NE-2C, providing a seamless fit for existing water-cooled condenser setups. By managing flow effectively, this valve prevents high head pressure trips and stabilizes operation in demanding environments where consistent refrigerant pressure regulation is critical for equipment longevity.

• Interchangeable Design: Fully compatible with the V46NE-2C, facilitating straightforward field replacement without piping modifications.
• Field-Proven Reliability: The Style 45 pressure element provides accurate sensing for non-corrosive refrigerant applications.

Common Questions

Is the V46NE-2 compatible with corrosive refrigerants?
No, this specific model is designed for use only with non-corrosive refrigerants. For applications involving sea water or corrosive fluids, a maritime-grade construction is required.

What is the difference between the V46NE-2 and the V46NE-2C?
These units are functionally and physically identical; the 'C' suffix typically denotes bulk packaging or specific distribution channels, but the technical specifications remain the same.

Can I adjust the setpoint while the system is pressurized?
Yes, the opening point range can be adjusted manually using the range screw to dial in the specific refrigerant head pressure required for your project.
