Dual Plate Check Valves have independent spring action for each plate and have pins which are precisely and permanently centred in the valve body. The Valves have shock dampers that ensure that there is no undue load on the stop pin and that the spring twist also is maintained in limit. The Valves have flanged/ wafer/ lug wafer end connections. The Valves have large and hydrodynamic flow passages that ensure minimum pressure drop. The Valves have heeling effect for the plates provided to avoid rubbing of the seats near closure and available in sizes ranging from 50 mm to 3000 mm. The Dual Plate Check Valves can operate under pressure ratings of 6/ 10/ 16/ 24 bar.
