One-way check valve Manufacturers introduce the failure causes and countermeasures of the cylinder:

common error

1) The limit bolt of the actuator falls off, causing the cylinder to leak air, causing the valve to fail to move or move slowly, failing to reach the predetermined opening.

2) The damage to the O-ring of the cylinder leads to air leakage, which causes the valve to operate difficult or unable to operate.

3) The deformation of the cylinder piston leads to an increase in the friction force, and the loosening of the cylinder bolts causes the cylinder to leak air, which makes the valve difficult to operate.

4) The linkage mechanism that the cylinder drives the valve body to move is loose or rusted, which makes the valve difficult to move.

5) The cylinder capacity is too small or the cylinder spring is faulty, which makes the valve difficult to operate.

Cause countermeasures

1) The cause of leakage at the piston seal is that the cylinder has poor finish; the assembly sealing of the piston ring is not enough, the use temperature of the seal ring is too high, and the seal is damaged for a long time. Troubleshooting method: grind the cylinder and re-adjust the cylinder limit bolt, and re-select the seal according to the operating temperature
ring, it should be installed correctly when replacing.

2) How to deal with the loosening of the cylinder limit bolts: Re-tighten the bolts.

3) The treatment method for the large friction force of the piston: re-apply lubricating oil, re-clean and grind the cylinder and piston.

4) The valve is difficult to move and cannot reach the fixed stroke, the spring of the actuator is not set enough or the spring is damaged, and the position of the limit block is inaccurate. Processing method: calibration, readjustment, spring replacement.
