English
The difference between a single clip LT type center line butterfly valve and a double clip center line butterfly valve is that the flange around the valve body has threaded holes. This product can be used for clamp connections between pipelines, as well as for connections between pipeline ends, for emptying pipeline media. This product has good valve body rigidity and can withstand high pipeline pressure, especially suitable for places with high safety factors, such as gas chemical and power plant industries.

6. Installation precautions
1. The pipeline flange must comply with the valve pressure standard, and it is recommended to use butterfly valve specific flanges for clamp butterfly valves.
2. Before use and installation, check whether the usage conditions match the performance of this butterfly valve.
3. Before installation, the valve chamber and sealing surface should be cleaned to prevent dirt from adhering. Before using new pipelines, the valve should be opened and the pipeline should be cleaned with air or water before use.
4. The two ends of the valve seat protrude from the valve body end face as flange sealing gaskets, and the sealing gasket cannot be added during the installation of butterfly valves.
5. Butterfly valves can be installed on pipelines at horizontal, vertical, and any angle, and can be used in both directions; Butterfly valves shall not be installed at the corners of pipelines and shall not be installed upside down.
6. When installing, the butterfly valve should be in the closed position to ensure that the butterfly plate does not collide with the pipeline flange, etc.
7. Confirm that the flange welding is correct, and it is not allowed to weld the flange again after the butterfly valve is installed.
8. If the butterfly valve is found to have abnormal opening and closing, the cause should be identified and the fault should be eliminated; Do not use methods such as knocking, smashing, prying, and extending the handle extension to forcefully open and close.
9. During transportation and storage of butterfly valves, the butterfly plate should not collide with hard objects and should be opened at a position of 8-10 ° to ensure that the sealing surface is not damaged during this period.
10. If the LT butterfly valve is used at the end of the pipeline, please specify it in the order.

XUVAL centric wafer butterfly valves with fixed liner feature an outstanding seating concept. The rubber is injection molded directly on the valve body forming a permanent bond. Consequently, there is no risk of deformation or dislocation of the liner making the valves suitable under vacuum conditions. The combination of the profiled disc edge and the excellent XUVAL rubber quality ensures maximum durability of the liner.
