Pentair Valves & Controls has introduced the new APIL 2000 compliant, Anderson Greenwood 4000 Series of pressure and vacuum relief valves. 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.
The 4000 Series pressure and vacuum relief valves are engineered to increase flow capacities and will fully open at 10% overpressure, helping protect tanks from physical damage caused by internal pressure fluctuations. These 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. The 4000 Series valves remain closed longer and enhance flow capacity, resulting in increased productivity and reduced evaporation.
The valve range is available in weight or spring-loaded designs and comes in two to 12 inch sizes. In accordance with API 2000, the valves have been tested on a square-edge flange connection and are available in a variety of coatings, such as PTFE and ECTFE, for protection from extreme temperatures and corrosive media.
