Dual High Pressure Pivot Gate Valve (DPHPGV)
Dual Pivot High Pressure Gate Valve (DPHPGV)
Dual’s Pivot High Pressure Gate Valve is built with a Steel body and features a heavy-duty Stainless Steel gate. Removable sleeves on either side of the gate provide a bi-directional bubble tight seal, with no metal parts in contact with the flowing slurry in open position. As the Dual Pivot High Pressure Gate Valve rotates on the pivot point and the gate moves through the Dual Ring sleeves from the side eliminating the damage caused to the sleeves by the traditional Gate Blade.
