The DK Series Slurry Valve from KV Controls incorporates a unique design , especially for slurries. The Process are only in contact with the rubber seats which uniquely seal when the valve are open. The stainless steel knife gate only get into contact with the process when the valve closes, once closed there is no flow to damage the gear. The seats can be replaced as a spare part without any special tools required. These 6 pieces DN250 PN10 valves was delivered from stock to a Base Mineral plant . The startup was on time due to fast delivery.
Linuo DK Series Knife Gate Valves are soft sealing linear shut off valves that are light weight with compact construction and convenient to install and use. Valves are full port in design to realize the characteristic of small flow resistance. When the gate is open.it will achieve direct current between valve and pipeline. Valves are available as manual with handwheel, or can be automated with actuator for remote operation. The cone-shape design of the gate provides strong cutting force. The die-casting rubber seat which can realize bi-directional sealing. The biggest characteristic of valves is that when they are fully open, the medium will not come into the valve chest, which can prevent the valve chest from settling pulp during the valve running online, then reducing maintenance cost.
KV Controls completed this project at a Base Mineral Plant.

The arc shape design of the gate provides strong cutting force.Each gate is precision ground and hard chrome plated as a standard.It provides superior abrasion and corrosion resistance.
Internal Packing
Packing gland and packing are internally located which realizes stable sealing and easy online maintenance.
Valve Body
Body is two piece design that is light weight and compact.The body is designed without any cavities, so there is no place for solids to accumulate. With this design, even with high solids content in the slurry, the valve will not jam.
Sealing Seat
Resilient and abrasion resistant rubber seat are die cast in a unique rubber mould, and have a metal support ring to extend the life of the valves. Seat material options are NBA, EPDM and Nature! Rubber.
Bottom Discharge Cover
The bottom discharge cover can easily be removed for routine cleaning. Customer can also outfit the valve with their own purge system.
