Description
The Johnson Controls V146EK-1 is a two-way, pressure-actuated water regulating valve engineered for reliable condenser water flow control in refrigeration and HVAC systems using standard non-corrosive refrigerants. Featuring a 3/4″ union sweat connection for straightforward field installation, this Style 46 valve responds directly to refrigerant system pressure to modulate condenser water flow — helping maintain optimal condensing pressure and system efficiency without the need for external power or controls.
Key Features
- Two-way, pressure-actuated operation — no external power required
- 3/4″ union sweat connections for easy installation and serviceability
- Opening point range: 70 to 260 PSI — suitable for a wide range of refrigerant system pressures
- Designed for use with standard non-corrosive refrigerants
- 30″ capillary tube with 1/4″ flare nut for remote pressure sensing
- Style 46 pressure element for accurate, responsive pressure actuation
How It Works
The V146EK-1 senses refrigerant discharge pressure through its 30″ capillary and 1/4″ flare nut connection. As system pressure rises, the valve opens to allow more condenser water flow; as pressure drops, the valve closes to restrict flow. This automatic modulation maintains stable condensing conditions and protects compressor efficiency.
