QT450 PN16 rising stem ductile iron sluice gate valve
Introduction
The valves disc is rubber-packed to get excellent sealing effect by the rubber's resilient deformation. Rising resilient seated gate valves solve the problem in general gate valves such as leakage, rusting etc. and saves installation space. It is used widely in tap water industry, sewage treatment, shipping construction, petroleum, chemicals, food, pharmacy, textile, electric power, metallurgy and energy system's pipeline to adjust and shut off fluids for sump pump.
