Description
This air Release Valve (Double Ball Type) from Leader covers 80 mm at Class 600. Supplied as part of a range covering the sizes and ratings commonly specified for industrial and building services installations. WCB carbon steel construction, rated for the steam and thermal-oil duties that rule out lighter body materials. 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.
