PRODUCT STRUCTURAL FEATURES
Flange-connection lifting plug valve acc. to ANSI is applicable to the cutting and connection of pipelines medium that are used in various industries such as petroleum, chemical industry, pharmacy, chemical fertilizer, power industry etc under nominal pressure of CLASS150-1500LBS, and working temperature of- 29~550°C.
1. The product has a reasonable structure, reliable sealing, excellent performance, and an attractive appearance.
2. The valve opening and closing process is conducted in a state where the sealing surface is isolated, preventing damage to the sealing surface.
3. Bi-directional flow, making installation and use more convenient.
4. Material and size of parts can be reasonably selected according to actual working conditions or user requirements to meet various engineering needs.
Principle of Valve Opening and Closing
The process of opening and closing the valve involves: When opening the valve, first turn the handwheel to lift the plug away from the sealing surface, then turn the handwheel by 90 degrees to align the plug channel with the valve body channel, thus opening the valve. When closing the valve, first turn the handwheel by 90 degrees to align the plug channel perpendicular to the valve body channel, then turn the handwheel to lower the plug, thus closing the valve.
