Products Detail

Specification of this Made In China Stainless Steel 304Pneumatic Knife Gate Valve

A knife gate valve is a component that utilizes a blade to cut through clogging of heavy liquids. These valves were designed to work in some of the most corrosive, erosive and abrasive environments in the world.

Knife gate valves were originally designed for the pulp and paper industry. Stringy pulp would get stuck between the wedge and the seat of a normal gate valve and prevent flow shut-off. Knife gate valves were specially designed with a sharp edge to cut through the pulp and seal.

The benefits of knife gates also include that they are easy to actuate and cheap to produce. As a result, use of knife gate valves quickly expanded into numerous other markets, including wastewater treatment, oil and gas, mining, and power, in a short period of time. Knife gate valves became advantageous in sludge and slurry applications because their blades can cut right through thick liquids easily.

Product advantage of this Made In China Stainless Steel 304Pneumatic Knife Gate Valve

Knife Gate Valve advantages:
1.Zero leakage
Unibody casting process is adopted. The inner groove of the valve body is lined with U rubber sealing strip, which is tightly sealed with the edge of the valve plate.

2.No blocking by the slag
There are no grooves at the bottom, making the flow of the fluid medium easy to plug.

3.More durable
Sealing strip design makes valve more durable.

4.Easy to install and disassemble
Small volume, smooth passage, small flow resistance, light weight, easy to install, easy to disassemble
