An ASTM A352 LCB Regulator is a regulator constructed with a cast steel body conforming to ASTM A352 Grade LCB specifications. These regulators are designed to be welded directly into the line, eliminating the need for flanges. They are utilized for controlling various substances such as Ammonia, R-12, R-22, R-502, as well as other common refrigerants, approved oils, and fluids used in refrigeration systems.
