Table of Back Contents BERMAD Irrigation Diaphragm Hydraulic Control Valves 1" - 16" IR-400 Series The IR-400 Series Valves are virtually free of the typical limitations associated with other diaphragm single chambered valves. The body design includes a full bore seat with unobstructed flow path. The internal design is using advanced rubber-based materials to achieve a solid, one piece elastomeric assembly including a flexible diaphragm, vulcanized with a rugged radial seal Disc. The diaphragm is carefully balanced and peripherally supported to avoid distortion and to protect the elastomer, resulting in long-life and controlled actuation even under harsh conditions. One diaphragm and spring fully meet the valve’s operating pressure range requirements. The IR-400 Series Valves are available in diameter sizes from 1"-16"; DN25 - DN400.
