Dual Flanged High Pressure Knife Valve (DFHPKG)
Dual Flanged High Pressure Knife Gate Valve (DFHPKG)
Dual’s Flanged High Pressure Knife Gate Valve is a true bi-directional knife gate valve. Its rubber sleeves are designed to seal and withstand the harsh abrasive duty inherent in mining & milling facilities, isolation is provided by the gate passing through the sleeve in such a manner that any solids that could potentially clog or jam the blade are purged out from between the sleeves to atmosphere, through the bottom of the valve housing.
