PENTA-WEDGE slurry gate valve. The PENTA-WEDGE gate is mounted and fixed on a wedge. The wedge assembly is suspended on the end of the spindle which allows movement around the axis of the spindle. The PENTA-WEDGE slurry valve is designed specifically for slurries, ash disposal, abrasive media and any application where heavy scale build-up is prominent. As the valve opens it scrapes the face of the gate which is Urethane coated and through this action any scale build up is removed.

The PENTA-WEDGE slurry valve range is rated to a maximum CWP of 150 bar (ANSI class 900) and is suited to applications in mining, mineral processing, power generation, pit dewatering, sand, gravel, chemicals, pulp and paper. The discharge section of the body has a circular cut-out in the lower area and during closure the flow is directed into this section causing a flushing action to remove any deposits. This prevents the gate from fouling on build up.

The valves are fabricated from Xlerplate boiler plate GR460R from BLUESCOPE as standard, and Stainless Steel 304, 306 UNS S32750 super duplex on request.

The PENTA-WEDGE slurry valve is designed for operation in the full-open or full-closed position and is not designed for throttle applications. Actuation options are hand-wheel, bevel gearbox, pneumatic, hydraulic and electric.
