KV Controls completed another successful project in the Mining and Power Industry.
KV DQ Knife Gate Valves are linear shut off valves that are light weight with compact construction. Valves are available as manual with hand wheel, or can be automated with pneumatic cylinder actuator for remote operations The arc shape of the gate of our knife gate valve is designed to be particularly suitable for cutting off fluid containing fiber or suspended particles, so the knife gate valves are ideal for many applications in the process industries of Pulp & Paper, Wastewater Treatment, Mining, Sugar Making and Chemical Processing.
DESIGN FEATURES
Gate
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 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.
