Mueller Industries AV3H-NK25J Transducer Valve

The Mueller Industries AV3H-NK25J Transducer Valve is a critical component for technicians requiring a direct replacement for B35162 in high-pressure refrigeration and air conditioning systems. Engineered for precision, this NPTFI x ODS industrial valve streamlines the integration of pressure transducers into existing liquid or suction lines. The Mueller AV3H-NK25J features a robust forged brass body designed to withstand the rigors of commercial HVACR environments, ensuring long-term seat integrity and leak prevention at critical tap points. By utilizing the NPTFI x ODS connection, contractors can achieve a secure, vibration-resistant fit that maintains system vacuum and refrigerant charge during transducer maintenance. Whether you are performing a transducer valve replacement or a new system build, this valve provides the flow control and access reliability necessary for accurate HVAC pressure monitoring and automated system diagnostics.

Key Benefits for Contractors

• Exact Retrofit Compatibility: Serves as the primary B35162 replacement valve, ensuring drop-in compatibility without the need for line modifications or additional adapters.
• Leak-Free Access: The specialized NPTFI (National Pipe Thread Fuel Internal) side port allows for the seamless attachment of electronic transducers while the ODS (Outside Diameter Solder) connections ensure a permanent, high-strength brazed joint.
• Enhanced System Resilience: Heavy-duty construction provides superior resistance to thermal expansion and mechanical stress, maintaining a hermetic seal in industrial HVAC systems.
• Efficient Serviceability: Allows for rapid sensing equipment swaps, reducing downtime during diagnostic cycles in commercial refrigeration applications.

Common Questions

What is the primary application for the AV3H-NK25J?
This valve is specifically designed to facilitate the mounting of pressure transducers in refrigeration systems, allowing the sensor to monitor line pressure while providing a secure connection point that minimizes potential leak paths.

Can this valve be used with high-pressure refrigerants?
Yes, the Mueller AV3H-NK25J is engineered for industrial-grade performance and is compatible with standard high-pressure refrigerants typically found in modern HVACR systems.

Why use an NPTFI x ODS configuration?
The ODS connection allows for a traditional brazed installation into the main piping, while the NPTFI port provides a specialized threaded interface that ensures a liquid-tight seal for sensors and transducers without the need for excessive pipe dope or tape.
