4-BOLT BRASS BODY FLANGE VALVES
The 4-Bolt Flange valves are most commonly mated to a companion flange on a refrigeration compressor.
This family of valves features a much larger 4-Bolt Flange at 2-1/2″ Bolt Center and 3-1/16″ Bolt Center sizes. Large internal ports help with Suction Line flow.
Valox Caps are standard on this valve series but the Brass Cap is also available as an accessory.
