4.1.
SINGLE-SEAT VALVE APPLICATIONS.
Single-seat valves may be cut-off or change-over type. Cut-offs are used to open and close the passage of fluid, whereas
change-overs are used to redirect the flow trajectory.
4.2.

•
Check for possible leaks and check that all the pipes and connections are watertight and free from leaks.
•
If the valve is supplied with actuator, ensure that the alignment of the valve shaft with the actuator shaft allows for a
smooth operation.
•
Check that the compressed air pressure at the intake to the actuator is that indicated in the Technical Specifications
(
Chapter 8
).
•
Mind the quality of the compressed air according to the specifications described in chapter 8 Technical Specifications.
