Product Description

Water Sealing Gate Valve, Flange end / Butt Weld end
Model NO. DS/Z44



SIZE: DN 1-1/2" ~ 24"
PRESURE RATING: PN10 ~ PN25

Water sealed Gate Valve is a on&off device for non-crossive mediums of water, steam, oil, pressure under 100Mpa, temperature less than 425ºC. It is especially suitable for condenser system of steam turbine in thermal power plant. The bonnet packing room has water sealing sturcture. Upon water pressure 0.6-1Mpa, the system is insulated from the air to be air tight.
