Cryogenic, Steam, Water, Air & Gases General Process Application Working Pressure: 15 – 10,000kPa The 7E range represents the next evolution in Mack’s 85 year history of supplying high-quality, reliable safety/relief valves. It has the added benefit of a simplified, easy-to-use numbering and selection system. This range of high-flow safety and relief valves is specifically designed and manufactured in accordance with AS1271—2003, Class ‘A’, for applications where pressure vessels require safeguarding against over-pressurisation. They activate in the event of an overpressure occurrence before the event becomes critical, protecting staff and valuable equipment. Mack’s 7E series is typically used to safeguard boilers, vessels and pipework from the risks of higher than desired pressures, ensuring protection for valuable resources while helping to avoid costly downtime. SELECTION & APPLICATION The 7E range is available in sizes from 15mm to 150mm, and in screwed, BSP, NPT and a variety of flanged connections. The 7E range suits applications across numerous industries, including building services, cryogenics, pharmaceuticals, mining and food & beverage. Simply select the materials, the size and the connection type, and set pressure. Safety Relief valves should be sized to their application and never sized on pipeline connection alone. Should it be required, one of our product specialists can perform a sizing calculation for you based on your application parameters.
