Product Details
This is a double orifice dual purpose air valve with full bore orifice and two stage closing action to prevent water hammer effects if too high a velocity is generated during filling of a pipeline, or at water column return.This valve is available in sizes 50mm through to 200mm in pressure rating 16 BAR, 25 BAR and 40 BAR and is now manufactured in South Africa. The standard valve will come equipped with the non-slam disc, but if this feature is not required it can be excluded with a slight reduction in price.This model meets all the requirements written in the specifications by the South African Water Industry and has the following additional benefits: The small automatic orifice is of the patented ARI rolling seal design which is much larger than its competition and has a self cleaning effect. The non-slam device is external to the pressure containing body and has no seals. The device can be left out if not considered necessary and its orifice size can be adjusted to suit special circumstances, while the valve is under pressure. The valve comes complete with all the usual ARI benefits including a 10 year guarantee against leaking seals and sealing at much lower pressures than its competition (down to 2m).Automatic componentARI patent, Rolling Seal Mechanism Dramatically reduces the possiblity of obstruction by debris. Discharges high air flow rates up to 160m3/h One size orifice for a wide pressure range (up to 40 BAR). Self cleaning mechanism.Special sealing mechanism design: combination of bronze and E.P.D.M rubber, assures long term maintenance free operation.Special FISO (fast in slow out) protection mechanism.FBE Coating to 250 micron standardother coatings available on request
