Johnson Controls V46EK-2 Valve

The Johnson Controls V46EK-2 is a commercial-grade, direct-acting pressure actuated water regulating valve designed specifically for head pressure control in water-cooled condensers. Constructed with a heavy-duty cast brass body, this 3/4 inch union sweat water valve manages flow based on refrigerant pressure changes to maintain stable condensing temperatures. It features an opening point range of 70 to 260 PSI, making it a reliable solution for systems utilizing non-corrosive refrigerants. The integration of a Style 46 pressure element, including a 48-inch capillary and a 1/4-inch flare nut, allows for precise sensing at the high-side service port. This model is technically identical to the V46EK-2C, ensuring direct compatibility for field replacements. For contractors optimizing HVAC water cooled systems, this valve provides the necessary throttling action to prevent excessive water consumption while ensuring consistent equipment performance during fluctuating ambient conditions.

Key Benefits for Technicians

• Precision Pressure Regulation: High-accuracy 70-260 PSI range ensures stable head pressure across varying load conditions.
• Durable Construction: Cast brass body and corrosion-resistant internal components provide longevity in demanding commercial environments.
• Easy Installation: The 3/4" union sweat connections simplify line integration and future maintenance access.
• Field Serviceable: Designed for straightforward adjustment and accessibility in restricted mechanical room piping.
• Proven Compatibility: Direct replacement for V46EK-2C, reducing time spent on sourcing and matching specifications.

Common Questions and Technical Support

What is the maximum water temperature for the V46EK-2?
This valve is designed for standard cooling water applications; however, ensure the inlet water temperature does not exceed 170°F (77°C) to prevent diaphragm fatigue.

Can I use this valve with ammonia systems?
No, the V46EK-2 is specifically engineered for non-corrosive refrigerants. Using it with ammonia will degrade the pressure element and internal seals.

How do I adjust the opening point?
The opening point is field-adjustable by turning the adjustment screw located on the spring housing. Turning the screw clockwise increases the pressure required to open the valve.
