Product use 

1. This valve is a new type of throttling, cut-off and emptying product. The valve adopts cage-shaped throttling, which has the characteristics of multi-level throttling effect, obvious throtling effect, reliable sealing, convenient operation and maintenance, etc. 

2. The valve adopts a double seal (hard and soft seal) to make the seal reliable, the cemented carbide cover can be more resistant to airflow washing and wear, and the double seal can be zero leakage under the condition of high-pressure gas medium. The valve has a long service life. 

3. The sealing surface of the valve seat is sealed with a taper, which is conducive to the valve itself cleaning the dirt attached to the sealing surface. 

4. The valve disc of the valve is equipped with a balance hole and a piston seal to ensure stable operation under the condition of full pressure difference between opening and closing. It is light and flexible, and the opening and closing torque is small. 

5. The throttle cut-off discharge valve and the double-acting throttle valve have both throttle and cut-off (the seal is zero leakage) and the throttle part is separated from the sealing surface to reduce the erosion of the small airflow to the seal. 

6. The double-acting throttle globe valve also has a multi-stage throttling function, with a large throttle pressure difference, which is suitable for throttling and cut-off under high pressure. 

7. The filler adopts a V-shaped filler structure with self-sealing ability, which does not need to be adjusted, and is extremely light to open and close. The filling mail is equipped with an auxiliary sealing grease injection structure, which makes the sealing performance of the valve filler reliable.
