The improvement of metal hard seal pneumatic ball valve Under the working conditions of high temperature, high pressure, high flow rate, severe erosion and corrosion, and high strength granular media, hard seal pneumatic ball valve is often used, but this kind of valve has low service life, large leakage, and short warranty period. Our company has studied a kind of erosion resistant ultra hard sealing pneumatic ball valve, and proposed a series of hard sealing pneumatic ball valves with a new concept of high quality, high grade travel, erosion resistance and long warranty period.

3. If the inlet and outlet holes of the solenoid pilot valve are blocked by oil sludge and other sundries, the sealing is not tight, the movable iron core is stuck, and the circuit is faulty, the clip type pneumatic butterfly valve can not be reversed normally. For the first three cases, clean the oil sludge and impurities on the pilot valve and movable iron core. The circuit faults are generally divided into control circuit faults and solenoid coil faults.
