Description
Leader air Release Valve, Double Ball Type, Flanged, available 25 mm to 200 mm at PN 10. Supplied as part of a range covering the sizes and ratings commonly specified for industrial and building services installations. The IS 210 cast iron body is the economical choice at larger bores. It suits steady water service but not lines that see mechanical shock. Flanged connections allow the valve to come out for overhaul with the pipework left in place. Fitted at the high points of a circuit, where trapped air would otherwise block flow. The table above gives the catalogue reference and price for each size in the range.
