Double Cylinder Knife Gate Valve
The double cylinder knife gate valve is a slide gate with pneumatic cylinder on both sides. This type of valve has no stem, the two cylinders push up the gate high when it’s open. Operated by manual, pneumatic or electric actuators, knife gate valve is widely used in the industrial application such as Pulp and Paper, Power plants, Wastewater treatment plants, Chemical plants, Iron and Steel Industry, Food and Beverage, Bulk Handling, Mining, etc.
Body:
- Integral body structure design, small flow resistance, easy assembly, minimize the possibility of shell leakage.
- Fixed guide claw, no groove design, the solid would not be accumulated and stuck.
Gate:
- The slide gate has a bevelled cutting edge. As a result, solids can be cut through, achieving a tight seal in the closed position.
- On request, the thickness of the knife gate valves gate can be increased for higher operating pressures and/or higher quality material can be used.
Seat:
- Side entry and replaceable seat design can be changed freely.
- The seat ring retainer avoids flow fluid flushing the seat ring.
- The material of the seat is selected according to the medium and service convince condition, choosing metal seal or soft seal.Metal seal is 304+stl or 316+stl.Soft seats are PTFE, EPDM, NBR, which have good sealing performance.
Test:
- Body test: Working pressurex1.5
- Seat test: Working pressurex1.1
Application:
knife gate valve is widely used in the industrial application such as Pulp and Paper, Power plants, Wastewater treatment plants, Chemical plants, Iron and Steel Industry, Food and Beverage, Bulk Handling, Mining, etc.
