Use a lever handle with excellent operability.

The high toughness fuselage with a seamless integrated structure using hot forging minimizes the risk of external leakage to the greatest extent possible.

Adopting a floating ball valve structure.

(What is a floating ball valve structure? Place a polytetrafluoroethylene sheet with excellent airtightness in the flow direction to support the ball. When the ball is completely closed, it presses against the auxiliary valve seat through differential pressure, making it airtight. It can close a more stable flow path.)

All airtight components are made of polytetrafluoroethylene with excellent corrosion resistance and durability.

The valve body design prevents the structure from popping out.

The airtight effect of internal pressure and the spring effect of conical springs (disc springs) further improve the airtightness.

Simply rotate the handle 90 degrees to easily open and close, and the valve's open/close status can be clearly identified by the position of the handle.
