Cut Off, Stop And Vent Valve

1. This valve is a new type of throttling, shut-off, and venting product. It adopts cage shaped labyrinth throttling, with multi-stage throttling effect, obvious throttling effect, reliable sealing, and convenient operation and maintenance.

2. The valve adopts dual sealing (hard and soft sealing) to ensure reliable sealing. The hard alloy cover can be more resistant to air flow erosion and wear, and the dual sealing can achieve zero leakage under high-pressure gas medium conditions. The valve has a long service life.

3. The sealing surface of the valve seat adopts a tapered seal, which is conducive to cleaning the dirt attached to the sealing surface of the valve itself.

4. The valve disc of the valve is equipped with a balance hole and a piston type seal, ensuring stable operation under full pressure difference conditions for opening/closing, with light and flexible opening and small opening/closing torque.

5. The throttling cut-off vent valve and the double acting throttling valve have both throttling and shut-off (zero leakage sealing) functions. The throttling part is separated from the sealing surface to reduce the erosion of the seal by the airflow.

6. The double acting throttling globe valve also has multi-stage throttling function, with a large throttling pressure difference, which can be applied to throttling and shut-off under high pressure.

7. The packing adopts a V-shaped packing structure with self sealing ability, which does not require adjustment and is extremely lightweight to open and close. There is an auxiliary sealing grease injection structure at the packing box, which ensures reliable sealing performance of the valve packing.
