The leakage of pneumatic valves mainly depends on the valve switch. To sum up, the increase in leakage of the pneumatic valve is mainly due to the following two factors: First, the valve spool in the pneumatic valve is worn due to the use of too long, resulting in the valve closing is not tight resulting in an increase in leakage; Namba tu em olsem sapos ol i miksim valv wantaim ol bodi bilong ol narapela kantri o ol diwai insait i gat sin, o aninit long kontrol bilong presa namel long ol kain kain midia, taim presa i narapela narapela bilong medium i bikpela, em bai mekim na rigiditi i go daun, na dispela i mekim na valv i no pas olgeta, na bihain em bai mekim valv bilong 'pneumatic valve' i kamap bikpela bilong skruim namba bilong ol.

Whether the signal pressure is unstable or the air source pressure is unstable, the pneumatic valve may be unstable. The unstable signal pressure will cause the output of the regulator to be unstable, and when the air source pressure is unstable, the pressure reducing valve will fail due to the small capacity of the compressor. It is also possible that the position of the amplifier spray block in the positioner is uneven, and spes namel long narapela narapela i kamapim wok bilong pneumatic valve i no stap gut bilong valv.
