Knife gate valve drive modes: manual, electric, pneumatic, hydraulic, bevel gear, electro-hydraulic, and pneumatic hydraulic.

Knife type gate valve appearance: two types of open stem and concealed stem

Knife gate valve material: cast iron, cast steel, carbon steel, stainless steel, fluorine lining, etc

Knife type gate valve seal: hard seal, soft seal, single-sided seal, double-sided seal and other materials for sealing

The working performance and installation of knife gate valve:

The installation and use of knife type gate valves: 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. The bolts at each connection point should be tightened evenly; 3. Check that the filling parts are tightly compressed to ensure the sealing of the filling,

It is also necessary to ensure that the gate opens flexibly; Before installing the valve, users must verify the valve model, connection size, and pay attention to the flow direction of the medium,

Ensure consistency with valve requirements; 5. When installing valves, users must reserve necessary space for valve actuation;

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 should not be bumped or squeezed at will to avoid affecting the sealing.
