The seal of the seat is sealed with a taper.It is helpful for the valve itself to clean the dirt attached to the sealing surface.
Balance holes are set in the disc of the throttle globe valve.

Piston seal ensures stable operation under pressure differential. Open light, flexible and open torque.
Throttling and double-acting throttle globe valves have both throttling and cut-off (sealing zero leakage). The throttle part is separated from the sealing surface to reduce the flow of airflow to the seal.
