Dual Wafer Knife Gate Valve (DWKG)
Dual Wafer Knife Gate Valve (DWKG)
Dual’s Wafer Knife Gate Valve has been designed as a space saving option for slurry applications. The full port design allows the gate to be fully isolated by the sleeves in the open position. When the valve is closed the gate pushes between the sleeves ensuring a 100% Bi-Directional bubble tight seal and zero downstream leakage. 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.
