Dual Pivot Wafer Gate Valve (DPWGV)
Dual Pivot Wafer Gate Valve (DPWGV)
Dual’s Pivot Wafer Gate Valve is built with a steel body and features a heavy-duty stainless steel gate. Removable sleeves on either side of the gate provides a bi-directional bubble tight seal, with no metal parts in contact with the flowing slurry, when open. When the Dual Pivot Wafer Gate Valve closes, the gate valve moves through the Dual Ring Sleeves from the side, eliminating the damage to the sleeves.
