Semi Lug Full Lug Ductile Iron Body Knife Gate Valve For Mining Applications
Description
TEKO knife gate valve is used within many different fields of applications. The valve has a gate with a bevel edge that effectively cuts through different media. In closing position, the gate is pushed onto a seal which gives a tight and reliable sealing. This special shut-off technique makes TEKO knife gate valves suitable for both fluids and dry media such pup, sludge, biomass, powder and different kinds of waste.
The body provided is either stainless steel or coated nodular iron, but it can also be supplied in a range of high alloy materials such as duplex, Hastelloy, titanium etc. About the seat material, there are several seat materials to meet the different working conditions.
Reliable Shut-off
With Reasonable design, the valve provides an effective shut-off on almost any flow. Minimal friction makes the valve easy to operate and also lower the ownership of acutuation.
