DMZ573H/X/F Carbon Steel Umbrella Gear Hidden Rod Knife Gate Valve

Product Introduction:

Knife gate valve, also known as knife gate valve or knife slurry valve, entered China in the 1980s. In less than twenty years, its usage has expanded from ordinary fields to a wider range of industries. Knife gate valves can be divided into manual knife gate valves, pneumatic knife gate valves, electric knife gate valves, bevel gear knife gate valves, clamp type knife gate valves, flange knife gate valves, chain wheel knife gate valves, electro-hydraulic knife gate valves, manual slurry valves, hydraulic slurry valves, pneumatic slurry valves, spiral gate valves, hidden stem knife gate valves, knife gate valves/knife gate valves, etc. according to different applications. Knife gate valves are used for coal preparation, gangue discharge, and slag discharge in mining power plants. It has developed into urban sewage treatment, from general industrial pipelines to food, sanitation, and other pipeline systems. The ultra-thin knife gate valve solves the difficult problems of high flow resistance, heavy weight, difficult installation, and large footprint of ordinary gate valves, flat gate valves, ball valves, globe valves, regulating valves, butterfly valves, and other types of valves due to its advantages of small volume, low flow resistance, light weight, easy installation, and easy disassembly. After the emergence of knife gate valves, a large number of general-purpose cut-off valves and regulating valves have been replaced by them.

Usage and characteristics:

DMZ573H umbrella gear knife type gate valve is widely used in various fields such as chemical industry, coal, sugar production, sewage, papermaking, fly ash treatment, bulk material transportation, food and beverage industry, and under harsh environmental conditions. It is an ideal sealed valve. Knife gate valves are particularly suitable for regulating and throttling pipelines in the paper industry. PZ573H umbrella gear knife type gate valve can be equipped with multiple flushing ports around the valve body as needed, which can be directly flushed with air, steam or water to prevent sediment from gradually accumulating. It is particularly suitable for fluids with difficult input.

1. Adopting a clamp type structure, it has a small volume, light weight, low flow resistance, and is easy to install and maintain.

2. A completely open channel can prevent the medium from depositing inside the valve.

3. The newly developed U-shaped sealing ring can ensure good sealing performance of the valve.

4. The external sealing of the gate is achieved by a sealing strip with elasticity embedded in the valve body, which can be adjusted with the help of screws and pressure plates.
