Knife Gate Valve

Knife Gate Valve Manufacturer in USA

A knife gate valve operates by permitting easy flow of thick media over soft seals with no obstruction. The media is cut up as it passes through the valve, which is how they function. These valves are now available in huge sizes and are employed in different processing plants all over the world. These valves are meant to seat the blade into a soft seal without causing any disruption, although they have low-pressure restrictions. It closes completely against a soft sealing barrier by elevating a plate with a planar or “knife” edge out of the flow passage. This edge can physically cut through various obstructions during closing. This supple sealing surface is often only appropriate for use in relatively low-pressure systems because it was not made to withstand high pressure. Rather than a throttled or partial-flow use, gate and knife gate valves are primarily designed for isolation or on/off service. They are particularly helpful in applications involving wastewater where corrosion is a significant problem. Therefore, having a knife made of acid-proof stainless steel is advantageous in addition to the valve design that is optimized for slurry media since it makes it less vulnerable to damages brought on by corrosion and as a result requires less frequent maintenance or even replacement.

• These valves are frequently employed in mining and mineral processing to regulate the flow of slurry and tailings, mixes of water and finely crushed particles. These valves are used in wastewater treatment facilities to regulate the flow of sludge, which is a combination of water and particles.
• These valves are used in the pulp and paper industry to regulate the flow of pulp, which is made up of a combination of water and wood fibres. They can manage the pulp’s high consistency and offer a tight shut-off to stop leaks. These valves are used in chemical processing to regulate the flow of corrosive and abrasive substances.
• These valves are used in power generation to regulate the flow of materials such as ash slurry in coal-fired power plants. These valves are used in the manufacturing of steel to regulate the flow of slag, a waste product of the steel-making process. The high temperature and abrasiveness of the slag can be handled by them, and they also offer a tight shut-off to avoid leaking.
