What causes the suction control valve to get stuck on Pentax EG29-i10c?

If the suction control valve gets stuck when depressed and does not return to the original position on your Pentax Medical Equipment, adjust the pressure of the suction source to an appropriate level. If the issue persists, replace the suction control valve if the seal rubber section is damaged or replace the suction control valve O-ring if it is broken. If silicone oil has not been applied, apply it to the suction control valve. Also, ensure no foreign material is stuck between the suction control valve and suction cylinder; remove any if found.
