Dual Flanged Slurry Knife Gate Valve (DFKG)
Dual Flanged Knife Gate Valve (DFKG)
Dual’s Flanged Knife Gate Valve is a true Bi-Directional gate valve. The rubber sleeves are designed to withstand the harsh abrasive duty within the mining and milling industry. Isolation is provided by the gate passing through the sleeves 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.
