Mueller Industries A14848 Straight Valve

The Mueller Industries A14848 is a professional-grade 1/4" straight packless diaphragm valve designed for high-performance refrigeration and air conditioning systems. Engineered with a forged brass body, this valve features full-size openings to provide maximum flow with minimal pressure drop, ensuring system efficiency. The LINEMASTER® series design utilizes a coreless, packless construction with two stainless steel diaphragms and one phosphor bronze diaphragm to ensure a positive seal and eliminate leakage common in standard packed valves. With a maximum operating pressure of 700 psig and a temperature range of -40°F to 300°F, this ODS solder connection valve is fully compatible with CFC, HCFC, and HFC refrigerants and their associated oils. The extended copper tube ends simplify the brazing process, protecting the internal valve components from heat damage during installation on the liquid or suction line.

• Forged Brass Construction: High-density body provides superior strength and durability under high-pressure 700 psig conditions.
• Packless Design: Triple-diaphragm (stainless steel and phosphor bronze) setup ensures leak-proof operation without the need for stem packing maintenance.
• Maximum Flow Capacity: Large internal ports prevent refrigerant pressure drop, maintaining optimal system capacity.
• Wide Compatibility: UL/cUL recognized for use with all common HVACR refrigerants and synthetic/mineral oils.
• Extended Solder Ends: Facilitates easy brazed installation while moving heat away from the critical diaphragm assembly.
