Info:

 Features: 

   F3LT43CX-1.5, DN800-1400 type chain sector blind valve is set by the two chain-driven spiral putter F43CX-1.5-type basis. Hand pull chain, screw and rod device drivers pay the valve and the valve plate to complete the release clamping action and action by turning the valve plate screw. The valve can be operated at a certain distance from the location of the pipeline, the pipeline can be operated on the ground height, improved security. The structure for the long series of valves, valve with expansion joints. Please refer to the installation diagram to determine the mounting direction.
Manual fan-shaped blind plate valve installation notes: 
    F43X-1.5, F43AX-1.5-type fan-shaped blind valve in the open left and right axial displacement of the valve body 16 to the application of 20mm. Therefore, the valve opening and closing process in the pipeline should also satisfy the elastic deformation or displacement of said displacement. Recommend installation in the following form. The rest of the sector model of the manual valve to ensure the blind conduit force does not act on the valve case, the predetermined mounting position do.
Second, the method of operation: 
   With a special wrench turn the screw counterclockwise rotating three connections, the valve body and the valve plate isolated and balanced, the right amount of space (about 16mm), turn the valve plate to the working position after confirmation. Reverse rotating bushing wrench to connect the valve plate in close contact with the body, the gas medium is not compromised. 
Third, when the operation is important to note: 
A, rubber seals and valve sticking or may not occur rub hard to prevent damage to rubber seals, damage the valve performance. 
B, you must use the special wrench, socket wrench, spanner or wrench operation. 
C, when the body is about to release, media to spill. To ensure safety, please take off the air supply, pressure, ventilation and other measures to ensure the safety.
