OneSeal face damage:
A common cause of inadequate closure of a high-pressure shut-off valve is a damaged sealing surface, resulting in an incomplete seal. This can be due to abrasion, corrosion, or other damage to the sealing surface, making it impossible to seal the valve completely when closed.
IILoose valve parts:
If the valve components of a high-pressure shut-off valve are loose or improperly tightened, it can also cause the valve to close incorrectly. This can be due to the bolts not being tightened properly or the nuts not being adjusted properly.
IIIBlockage inside the valve:
If there is a blockage inside the high-pressure shut-off valve, the valve may not be completely closed when closed. This could be due to sediment, impurities, or other substances in the pipe clogging the inside of the valve, preventing the valve from closing completely.
FourthImproper valve operation:
Improper operation of the high-pressure shut-off valve can also result in inadequate shut-off. For example, if the operator is too impatient or rough when closing the valve, it can cause the valve to not close completely.
FiveValve damage:
If the high-pressure shut-off valve itself is damaged, such as a bent or worn valve stem, it can also cause the valve to close incorrectly.
To sum up, the main reasons for the failure to close the high-pressure globe valve are damage to the sealing surface, loose valve components, internal blockage of the valve, improper operation of the valve and damage to the valve. If necessary, the valve should be repaired or replaced to ensure that the valve can be closed properly.
