Our Products
Superior Refrigeration's Integra Seal® Ball Valves head the list of industry specified products for air conditioning and refrigeration service. These valves are specified by many quality conscientious customers including major refrigeration rack manufacturers, major supermarket chains, and manufacturers of air conditioning equipment. All our products are fully compatible with fluorocarbon refrigerants and associated oils. Qualification testing performed at five times the working pressures in our state of the art Research and Development Laboratory in Washington, Pennsylvania have verified design calculations to performance and product life. For example, the stringent qualification testing of our ball valves included life cycle testing and external leak testing to comply with EPA regulations and the intent of the Montreal Protocol. All ball valve designs have surpassed 1,000,000 full pressure cycles (25 year life equivalent). External leak rates for our ball valves tested less than 0.01 oz/yr or about 0.25 gm/yr. In addition, we will consider your special requirements or specifications.
