Let’s talk about how to use pneumatic knife gate valves.

The knife gate valve, also known as the knife-type gate valve, blade gate valve, slurry valve, or mud valve, features a gate plate as its closing member. The motion direction of the gate plate is perpendicular to the flow direction of the fluid. The medium is cut off by a blade-shaped gate plate that can slice through fibrous materials. The gate plate has two sealing surfaces; in commonly used wedge-type gate valves, these two sealing surfaces form a wedge shape, with the wedge angle varying depending on the valve’s specifications.

What are the general advantages of slurry valves?

The slurry valve has the following advantages: Its structure is simple because it adopts a flange-type design. Compared with conventional valves, this valve boasts a smaller size and lighter weight. Its installation location is unrestricted, making it easy to set up. Due to its compact footprint and minimal space requirements, it plays a positive role in reducing plant floor area, lowering building height, and saving on capital investment.

Learn about the development history of knife gate valves.

Gate valves entered China in the 1980s, and within less than two decades, their application scope has expanded from conventional areas to a wide range of industries. They are now used not only in coal preparation, gangue removal, and slag discharge at mines and power plants, but also in urban wastewater treatment. Moreover, their use has extended from general industrial pipelines to specialized pipeline systems in sectors such as food, sanitation, and pharmaceuticals.

Introduction to the Basic Advantages and Disadvantages of Slurry Valves, along with Some Common Sense on Their Classification

A slurry valve is a type of valve in which the gate (or disc) moves vertically along the centerline of the flow passage. In piping systems, slurry valves are primarily used for on-off service. Slurry valves are widely employed and generally find application in cutting devices with nominal diameters of DN≥50mm; even smaller-diameter cutting devices may also utilize slurry valves. Now, let’s take a closer look at the basic advantages and disadvantages of slurry valves, as well as some handy classification tips!

Let’s talk about how to install knife gate valves.

The closing and opening element of a knife gate valve is the gate plate, whose direction of motion is perpendicular to the flow direction of the fluid. Manual knife gate valves can only be fully opened or fully closed; they cannot be used for regulation or throttling. The gate has two sealing surfaces. In commonly used gate valves, these two sealing surfaces form a wedge shape. The wedge angle depends on the valve’s specifications and typically measures 50 degrees. The gate of a wedge-type knife gate valve can be either rigid or flexible.
