4-BOLT CAST IRON BODY FLANGE VALVES
These workhorse valves are always mated to a companion flange on a refrigeration compressor. They are used for both Discharge Line and Suction Line applications.
They feature massive flow and the Flange sizes are often compressor dependent.
The 4F13STA-CIA Brass Body Valve is a lower cost alternative to it’s Cast Iron counterpart and the availability is better.
The newer Cast Iron Valves are supplied with METRIC threaded Bottom Caps and care must be used when replacing the caps.
