Pentair Valves & Controls introduces the new Anderson Greenwood 4000 Series of pressure and vacuum relief valves, compliant with the latest API 2000 standard. Developed alongside the industry standard, these are the first high capacity full lift valves verified to meet the requirements of the seventh edition of API 2000, which covers normal and emergency vapor venting requirements for bulk liquid storage tanks.
The 4000 Series pressure and vacuum relief valves are engineered to provide increased flow capacities and will fully open at 10 percent overpressure, helping protect tanks from physical damage caused by internal pressure fluctuations. As a result, the valves can be set more closely to a storage tank’s maximum allowable working pressure (MAWP) or maximum allowable working vacuum (MAWV), enabling customers to fill and empty tanks more quickly, and operate them at higher pressures
