Description
The Johnson Controls V46EA-3 is a commercial-grade, pressure actuated water regulating valve engineered for reliable flow control in demanding HVAC and refrigeration applications. Featuring a high pressure bellows actuator, this valve responds directly to system pressure changes to automatically regulate condenser water flow — helping maintain optimal system efficiency and protecting equipment from pressure extremes.
Key Features
- Pressure actuated operation — no external power source required
- Open-on-rise pressure response for automatic condenser water flow regulation
- High pressure bellows construction for durability and precise pressure sensing
- 3/8″ NPT connection for easy installation in standard piping systems
- Wide operating pressure range of 70–300 PSI to suit a broad range of commercial HVAC and refrigeration systems
- Commercial-duty build quality for long service life in continuous-operation environments
Specifications

Application
The V46EA-3 is ideal for use in commercial cooling systems, chillers, and refrigeration equipment where condenser water flow must be regulated in response to refrigerant head pressure. The open-on-rise design ensures that as system pressure increases, the valve opens to allow greater water flow, preventing high-pressure lockouts and maintaining system performance. The high pressure bellows mechanism delivers accurate, repeatable response across the full 70–300 PSI operating range.
