When open the YFL rising stem orbit plug valve, the plug separates from the seat first before rotation so that there will be no contact between the sealing face of plug and seat. Without abrasion during opening and closing, the YFL rising stem orbit plug valves will have lower operation torque and much longer service life.
YFL rising stem orbit plug valves technical features:
1. Convenient On-line maintenance, no need to remove the valve from pipeline, only need to dismantle the bonnet for repair and maintenance
2. Full bore, suitable for pigging ball
3. Body inside is overlaid with hard chrome
4. Automatic relief device to release overpressure when the valve is fully closed
