Johnson Controls V46AA-33 Regulating Valve

The Johnson Controls V46AA-33 is a heavy-duty pressure actuated water regulating valve designed for commercial refrigeration systems. This open-on-rise valve features a 3/8-inch NPT connection and is specifically engineered to maintain head pressure by modulating the flow of water through a condenser. With a broad pressure adjustment range of 70 to 260 psi, this unit offers precise control for systems using high-pressure refrigerants. The V46AA-33 serves as a direct replacement for the V46AA-33C, ensuring seamless integration into existing piping layouts. Its bellows-actuated design provides a rapid response to load fluctuations, preventing compressor cycling issues and ensuring optimal heat transfer. Built for durability in demanding mechanical rooms, this direct-acting water valve utilizes a corrosion-resistant internal construction to handle commercial condenser cooling applications where consistent pressure regulation is critical for system longevity.

• Flexible Pressure Range: The 70-260 psi setpoint range accommodates various refrigerant types and ambient conditions.
• Direct Compatibility: Identical specifications to the V46AA-33C model allow for a drop-in 3/8" NPT installation without modifications.
• System Efficiency: Accurate modulation reduces water consumption and maintains stable head pressures during peak loads.
• Rugged Build: Designed to withstand the high-cycle demands of commercial-grade water-cooled condensers.

What is the difference between the V46AA-33 and the V46AA-33C?
Technically, there is no functional difference; the models are identical in fit, form, and function for your piping and pressure requirements.

How do I adjust the opening point on the V46AA-33?
The opening pressure is adjusted via the range spring screw located at the top of the valve housing, allowing for field calibration to meet your specific system design.

Can this valve be used with glycols?
Yes, the internal materials are compatible with standard non-corrosive water and glycol solutions commonly found in closed-loop cooling systems.
