Mueller Streamline b32930 Brass Compressor Valve

Product Description

The MUELLER STREAMLINE b32930 is a brass compressor service valve designed for four-bolt mounting with solder end connections. Built for refrigeration and air conditioning compressor service work, this valve allows technicians to isolate the compressor from the system for service, replacement, or pressure testing without a full system pumpdown. The mid-seat position provides a working port for gauge access. It is rated to 700 psi maximum allowable pressure (MAP) and handles operating temperatures from -40 degrees F to 300 degrees F, making it suitable for a wide range of refrigerants and operating conditions.

This compressor valve is used in commercial and residential refrigeration systems and air conditioning equipment where direct compressor access is required. The four-bolt flange mount secures the valve to the compressor body, and solder end connections integrate with copper refrigerant line sets. The 1 5/8 inch connection size suits larger compressor applications commonly found in commercial refrigeration, chiller systems, and high-capacity HVAC equipment. Installation is performed by licensed HVAC-R technicians as part of compressor service or replacement procedures.

Key Features

• Four-bolt flange mounting for direct compressor body attachment
• Solder end connections compatible with copper refrigerant piping
• Mid-seat position provides gauge port access during service
• 700 psi MAP rating suitable for high-pressure refrigerant applications
• Wide operating temperature range: -40 degrees F to 300 degrees F
• Brass construction for corrosion resistance in refrigerant environments

Compatibility

Designed as an OEM-style replacement compressor service valve for commercial and residential refrigeration and air conditioning systems requiring a four-bolt mount, 1 5/8 inch solder connection valve.

Installation Notes

Installation should be performed by a licensed HVAC-R technician in accordance with applicable mechanical codes and EPA Section 608 refrigerant handling regulations. Recover all refrigerant from the system before removing or installing compressor service valves. Solder connections require proper nitrogen purge during brazing to prevent internal oxidation. Confirm all four mounting bolts are torqued evenly and leak-check all connections before returning the system to service.
