There are nine functions of the regulating valve, and the nine functions of the full function ultra light regulating valve are excellent, so it is called the full function valve.
Good regulating function The regulating function is one of the main functions of the regulating valve, which is manifested as ① flow characteristics; ② Adjustable ratio R; ③ Small opening working performance; ④ Flow coefficient; ⑤ Adjust the speed. Full function ultra light regulating valve R=100, making good regulation of small opening; Kv value is large, 2-3 times of that of single and double seat valves and sleeve valves.

(2) If the high pressure ball valve is in the closed state, it is very likely that there is some medium left in the valve body, and the valve body will also bear a certain pressure. Before the maintenance of the ball valve, it is necessary to close the shut-off valve in front of the ball valve, and then carry out the inspection work, in order to release the internal pressure of the valve body. The starting ball valve is used here, so the power supply and air supply need to be disconnected first.
