1. Low torque operation - Rotating valve seat design, easy and effortless opening and closing
2. Bidirectional zero leakage - Precisely ground sealing surfaces, in line with international standards
3. High pressure and high temperature resistance - Maximum pressure rating of PN100, temperature range of -196℃ to 550℃
4. Long service life - Hardened ball body, self-compensating valve seat design
5. Full diameter flow - Flow channels are of the same diameter as the pipeline, resulting in low pressure drop
6. Multiple drive methods - Supports manual/ pneumatic/electric control
7. Easy maintenance - Modular design, valve seats can be replaced quickly

When the disc of the lift check valve slides along the vertical center line of the valve body and the medium flows forward, the disc is lifted by the fluid thrust and the medium passes smoothly; When the medium stops flowing or reverse flowing, the valve disc quickly closes under the action of its own gravity and the reverse thrust of the fluid to prevent the medium from flowing back. This valve is usually equipped with a guide sleeve to ensure that the disc remains smooth during lifting and accurately falls back onto the seat.
The globe valve is mainly composed of valve body, valve cover, valve disc and valve stem. The handwheel applies a certain torque at the upper end of the valve stem. The valve stem is passed to the valve petals through the valve stem, so that it moves up and down along the valve stem axis to achieve fully turned on or fully closed movements. The force applied by the handwheel acts on the disc to hold it against the seat to seal. The single disc globe valve is designed to enter the medium by the valve disc sealing surface below, the medium force is opposite to the direction of valve closing, so the valve closing torque is large, so the single disc globe valve is mainly used in low pressure or small diameter pipelines. At the same time, the globe valve does not rub with the valve seat before the valve is closed, thereby reducing the wear of the cover surface and effectively extending the service life of the valve.
