Description
Leader’s air Release Valve (Double Ball Type) is supplied in 80 mm at Class 300. Supplied as part of a range covering the sizes and ratings commonly specified for industrial and building services installations. A cast carbon steel body to ASTM A216 WCB handles the temperatures and pressures of steam and hot oil, where bronze or iron would not be rated. 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. Full dimensions, catalogue references and current pricing for every size are listed in the table above.
