It is common practice in the ammonia refrigeration industry to install a three-way isolation valve upstream of relief valves protecting an ammonia refrigeration pressure vessel. For vessels larger than 10 ft3, this is required by most model codes and standards. These three-way valves allow a relief valve to be replaced without the hassle of pumping […]
It’s widely known that pressure vessels must be equipped with over-pressure protection (2015 ASME B&PVC UG-125), often in the form of a pressure relief valve. Properly sizing a relief valve requires engineering analysis which accounts for the type of over-pressure scenarios that might occur. In most cases, model codes and standards (RAGAGEPs) specify the relief […]
