Make sure that no inappropriate items get between
the valve body and the actuator.
5.3 All models (PV, PVE and PVE/S)
The actuator in all models (PV, PVE and PVE/S
raises) 0.5 x valve nominal diameter. Allow enough
headroom for installation and operation.
The valve nominal size means the inner diameter of
the sleeve. The pipe inner diameter should match this
diameter as closely as possible. Whenever possible,
install the actuator in a vertical position. Valve can be

assembled either way in terms of flow direction.
If the valve must be installed horizontally, the
actuator must be supported to ensure the smooth
operation, especially if the actuator is heavy. Install a
sliding surface under the actuator (Figure 14).
The support can be fixed on the wall (1), on the floor
(2) or the pipeline (3).
The valve can be installed in either way depending on
the flow direction.
When installing the valve to the pipeline, it must be in
the open position. Tighten the flange bolts smoothly
crosswise.
