Johnson Controls V46EA-3 Valve

The Johnson Controls V46EA-3 is a high-performance pressure actuated water regulating valve designed for commercial refrigeration systems. Built with high pressure bellows, this 3/8" NPT valve operates on an open on rise action, modulating water flow to maintain stable refrigerant head pressure in water-cooled condensers. This model features a wide 70-300 PSI adjustment range, making it a versatile choice for various high-pressure applications. The V46EA-3 is technically identical to the V46EA-3C, ensuring seamless integration into existing service protocols. Designed with a pressure-balanced seat, the valve remains unaffected by fluctuations in water supply pressure, providing consistent flow control. The "take-apart" construction allows for internal access and maintenance without removing the valve body from the piping, a critical time-saver for field technicians. With no sliding parts in the water passages, it effectively minimizes sediment buildup and operational sticking.

• Universal Refrigerant Compatibility: Suitable for use with all standard non-corrosive refrigerants, streamlining truck stock for multi-system service.
• High-Pressure Durability: Equipped with robust bellows engineered to withstand the demanding cycles of modern commercial cooling.
• Service-Friendly Design: Features an accessible range spring for easy manual flushing of debris without losing the calibrated setpoint.
• Direct-Acting Precision: Specifically calibrated to open as head pressure rises, preventing compressor overheating and optimizing system efficiency.
• Compact 3/8" NPT Connection: Standard threaded ports ensure a reliable, leak-free fit in tight mechanical envelopes.

Common Questions

Is the V46EA-3 compatible with my older V46EA-3C system?
Yes, the V46EA-3 and V46EA-3C are identical in technical specifications, mounting footprint, and performance characteristics, allowing for direct drop-in replacement.

Can this valve be used for ammonia systems?
Standard V46EA models are designed for non-corrosive refrigerants. For ammonia applications, a specific ammonia-compatible power element must be utilized.

How do I adjust the opening point of the valve?
The opening point is adjusted via the screw at the top of the range spring housing. Use a standard service wrench to increase or decrease the PSI setpoint within the 70-300 range.
