Product Description:

Manual clamp type knife gate valve, also known as manual insert plate valve or manual gate valve, is suitable for medium pipelines such as syrup, pulp, sewage, coal slurry, ash, dust, slag water mixture, etc. It can be used for medium cutting and throttling. This knife gate valve is suitable for horizontal installation and inclined installation.

Knife gate valve, also known as knife gate valve or knife slurry gate valve. Its application range is very wide, from coal preparation, gangue discharge, slag discharge in mines and power plants, to urban sewage treatment; From slurry transportation in cement and paper mills to professional pipelines in food, hygiene, medicine, and other fields. The ultra-thin designed knife gate valve solves the difficult problems of large flow resistance, space occupation, slag accumulation, installation and maintenance of ordinary gate valves, flat gate valves, ball valves, globe valves, regulating valves, butterfly valves and other valves due to its advantages of small volume, light weight, small flow resistance, no slag accumulation, easy installation and disassembly. Therefore, a large number of universal shut-off valves and regulating valves have been replaced by radial gate valves.

The manual knife type gate valve has a simple and compact structure, reasonable design, lightweight and material saving,The advantages of reliable sealing, lightweight and flexible operation, small size, smooth channel, low flow resistance, light weight, easy installation, easy disassembly, etc., can withstand working pressure1.0MPa-2.5MPa, using temperature-29-650℃Normal operation under normal circumstances. The blade gate valve has a shearing function on its gate plate, which can scrape off the adhesive on the sealing surface and automatically remove debris. The stainless steel gate plate can prevent sealing leakage caused by corrosion. This type of valve should generally be installed horizontally in pipelines.

Installation and use of manual knife gate valve

1.Before installation, it is necessary to check the valve chamber and sealing surface, and no dirt or sand particles are allowed to adhere to them;

2.Bolts at each connection point,Require uniform tightening;

3.Check the filling position and ensure that it is tightly pressed to ensure both the sealing of the filling and the flexibility of the gate opening;

4.Before installing the valve, users must verify the valve model, connection size, and pay attention to the flow direction of the medium to ensure consistency with the valve requirements;

5.Users must reserve necessary space for valve actuation when installing valves;

6.The wiring of the driving device must be carried out according to the circuit diagram;

7.Knife type gate valves must be regularly maintained and must not be bumped or squeezed at will to avoid affecting the sealing.
