Johnson Controls V46AC-26 Valve

The Johnson Controls V46AC-26 is a professional-grade 3/4" NPT pressure actuated water regulating valve engineered for high-demand commercial refrigeration applications. This direct acting valve is designed specifically for systems utilizing non-corrosive refrigerants, featuring a robust cast brass body to withstand rigorous mechanical stress. With an adjustable opening point range of 70 to 260 PSI, it provides precise head pressure control by modulating the flow of cooling water through the condenser. The V46AC-26 employs a Style 5 pressure element equipped with a 1/4" external flare fitting, ensuring a secure and leak-resistant connection to the high-side refrigerant line. This model is a drop-in replacement for the V46AC-26C, maintaining identical performance specifications. For technicians managing condenser water flow, this valve ensures stable subcooling levels and optimal compressor efficiency by reacting instantly to fluctuating refrigerant pressures without the need for external power sources.

Key Benefits

• Standard flow commercial design optimized for heavy-duty service cycles in HVACR environments.
• Cast brass construction provides superior durability and resistance to corrosion in non-potable water systems.
• Direct acting modulation allows for instantaneous response to refrigerant pressure changes to maintain setpoint.
• Style 5 pressure element featuring 1/4" flare simplifies installation for field technicians.
• Wide pressure range of 70 to 260 PSI accommodates various refrigerant types and ambient operating conditions.

Common Questions

Is the V46AC-26 compatible with ammonia systems?
No, this valve is designed for use only with non-corrosive refrigerants. For ammonia applications, a stainless steel or specific alloy valve must be utilized.

What is the difference between the V46AC-26 and the V46AC-26C?
These units are functionally identical. The "C" suffix typically denotes bulk packaging or specific distributor labeling, but the technical specifications and dimensions remain the same.

How do I adjust the opening point on this water regulating valve?
Adjustments are made via the range spring screw. Turning the screw clockwise increases the opening point pressure, while counter-clockwise decreases it.
