urethane lined slurry knife gate valve

Urethane Lined Slurry Knife Gate Valve

Dual's Urethane Lined Slurry Knife Gate Valve is built with a cast iron body and features a heavy-duty stainless steel blade.  The one piece urethane liner is moulded throughout the body and chest area.  A cut away in the urethane liner downstream side helps to clean out the seating area.

slurry air release valve

Slurry Air Release Valve

Air/Vacuum Valve’s function is to automatically exhaust large volumes of air from the system when it is being filled and also to allow air to re-enter the pipe line when being emptied. The orifice size is generally the same size as the valve inlet and outlet. In Operation, when the system is filled, the fluid lifts the ball until it closes the orifice. The orifice will remain closed until the system is emptied. Air may enter the valve and displace the fluid while the system is in operation, however, internal pressure will continue to hold the valve closed. The valve will not re-open until the system pressure drops to near atmospheric pressure and the ball is no longer buoyant.

wafer slurry gate valve

Wafer Slurry Gate Valve

Wafer Slurry Knife Gate Valve is built with a steel body and features a heavy-duty stainless steel blade. Removable seats on either side of the blade provide a bi-directional bubble tight seal, with no metal parts in contact with the slurry.

compact flanged ported gate valve

Compact Flanged Ported Gate Valve

Compact Flanged Ported Gate Valve has a stainless steel blade machined with a round orifice hole, in line with seat ID when the valve is in the open position.  When the valve is closed the ported blade will move sideways sealing the valve.  Due to the seal being constantly engaged against the gate, stroking the valve closed forces the gate progressively between the two matching sleeve ends until it reaches the fully closed position - at which point the sleeves each butt up tightly against either side of the gate, effectively sealing and completely containing the line pressure. Build up of material to prevent full gate travel is eliminated as there are no areas for such material to accumulate.  Any material discharged between the sleeves during stroking open or closed is collected within the containment area of the valve body and drained via the multiple flushing ports in the body. The Ported Gate Valve can be used as a man-safe line blasting valve.

free flow valve

Free Flow Valve

Free Flow Valve operates on the discharge side of the pump as the flow through the pipeline starts or stops, the ball automatically rises or falls, opening and closing the valve. This occurs without noticeable shock or hammer, regardless of the line pressure or the speed of closure.

high pressure slurry knife gate valve

High Pressure Slurry Knife Gate Valve

High Pressure Slurry Knife Gate Valve is built with a cast SG Iron GR. 42 or fabricated body and features a heavy-duty stainless steel blade. Removable sleeves on either side of the blade provide a bi-directional bubble tight seal, with no metal parts in contact with the slurry.

flo stop high pressure mine dewatering check valve

Flo Stop Valve

Flo-Stop Valve has a reinforced stainless steel ball. The unique design of the valve allows free movement of the ball. The ball lifts out of the liquid without any interference. As the pump stops, the ball falls back and positively locates in the stainless steel seat due to its own weight and back pressure of the liquid. The higher the pressure the better the secondary Linatex seal will seal.
