R301 Dynamic Triple Function Air Release Valve

Ventilation outlet in nominal size (large opening cross-section according to the flange size).
Intake of large volumes of air on shut-of of the system, while pipelines are being drained.
Efficient, high performance ventilation protects pipeline from vacuum related damages.
High velocity air discharge prevents premature closure, thus safeguarding optimum ventilation during the process of filling pipelines or containers.
Large orifice for outlet and intake of large air volumes, during filling and emptying of pipeline.
Continuously reliable ventilation of air inlets under normal operating conditions.
Non slam closure by the help of two stage closing design.
Excellent corrosion protection, all stainless-steel internal parts
The housing is made of ductile iron and coated with high quality epoxy powder All uncoated metal is stainless steel. High capacity inlet sectional area and outlet are equal area.
Casting Standard: EN 1563:2011 / TS EN 1074-4 / TS EN 1092-2.
Hydrostatic test pressure for seat: PN x 1.1 , for shell: PN x 1.5 according to EN 12266-1.
