FAQ
Is this valve compatible with R410A refrigerant?
Yes. It is designed for R410A and also works with R22, R134a, R407C, and R32.
What size valve do I need for a 2-ton AC unit?
2-ton units typically use 3/8″ (10mm) (liquid line) and 1/2″ (12mm) (suction line) valves.
Can I install this valve myself?
Installation requires welding/soldering and refrigerant handling. Professional HVAC installation is recommended to avoid leaks or damage.
What’s the difference between straight and elbow models?
Straight valves align with copper tubing for inline installation; elbow valves change direction (90°) for tight spaces or complex piping.
Does this valve come with installation accessories?
The valve includes a protective cap. Welding materials, flare nuts, and tools are sold separately.
What are the advantages of Smartclima AC service valves?
Smartclima outdoor unit service stop valves adopt thickened copper tubes and solid brass bodies with strict production standards. Both straight and elbow types are available. Each valve is precisely processed to ensure stable refrigerant flow, and the durable structure effectively avoids air leakage and damage during long-term use, which is an ideal choice for HVAC repair and assembly.
Do you offer different types of AC outdoor unit stop valves?
Yes. Smartclima provides both straight and elbow style service stop valves in full sizes ranging from 1/4″ to 3/4″. We control every detail of material selection and machining, including copper tube wall thickness, flaring size and overall dimension. Our products are lightweight, sturdy and easy to install for air conditioner maintenance and refrigerant charging work.
