The medium should preferably flow in the opening direction of the valve disk to
avoid pipe hammers when the valve is opened or closed. Should this not be
possible due to technical reasons related to the plant or process, it is
recommended to switch the valve without pressure. Both measures prevent
pressure hammers when the valve is opened or closed.
The valve is monitored, controlled and operated by the customer's installation.
Hint!
The manufacturer will not accept any liability for damage resulting
from any use of the valve which is not in accordance with the
designated use of the valve. The risk is borne solely by the operating
company.
