Flange Connection Lifting Plug Valve

Flange-Connection Lifting Plug Valve Introduction:

Flange-Connection Lifting Plug Valve is applicable to the cutting and connection of pipelines medium that are used in various industries such as petroleum, chemical industry, pharmacy, chemical fertilizer, electric power industry etc. under nominal pressure of Class 150lb-1500Lbs and working temperature of -29-550 Deg C.

Flange-Connection Lifting Plug Valve Main Structural Features:

1. The product has reasonable structure, reliable sealing, excellent performance and beautiful apperance.

2. Opening and closing of the valve is carride out while the sealed surface is taken off, so it will not cause abrasion on the sealed surface.

3. Its characteristic double-direction flow makes installation and use more convenient.

4. The materials of the parts and sizes of flanges can be reasonably configured according to the actual operation condition of the requiremetns of the customers, so as to meet the various needs of engineering.

Flange-Connection Lifting Plug Valve Opening and Closing Principle

Process of opening and closing of the valve, when opening the valve, first of all, turn the hand wheel to make the plug lifted and separated with the sealed surface, then turn the handle by 90 degree to connect the channel of plug to the channel of valve  body, so that the valve is opened;

when closing the valve, first of all, turn the handle by 90 degree to make the channel of plug vertical to the channel of valve body, and then turn the hand wheel to descend the plug, so that the valve is closed.
