Features
●Moderately price:
Optimized flow rates mean smaller ball valves can be selected. Low torque means you
can combine them with small, less expensive rotary actuators.
●Long life expectancy:
Maintenance-free construction, also thanks to low friction stem and polished ball made of
chrome-plated DZR brass.
●Simple mounting:
The brackets, premounted on the actuators, means you can mount them on the ball
valves without tools.

Δpmax for VAI60.. and VBI60.., for details, see table on equipment
combinations
Δpmax
=
Maximum permissible differential pressure over the ball valve, valid for the
entire positioning range of the ball valve rotary actuator unit; if low noise
operation is desired, we recommend a maximum permissible differential
pressure of 200 kPa
Δpv100
=
Differential pressure over the fully opened ball valve and over the control
path at a volume flow V100

Cavitation
Cavitation increases wear and tear of the ball and seat and results in unwanted noise.
Cavitation can be prevented by not exceeding the differential pressures as per the flow
diagram and maintaining the static pressures depicted below.
Δpmax
=
Differential pressure at a nearly closed ball valve
to largely avoid cavitation
p1
=
Static pressure at the ball valve inlet
P3
=
Static pressure at the ball valve outlet
M
Pump
J
Water temperature
Example with hot water:
Pressure p1at ball valve inlet: 500 kPa (5 bar)
Water temperature: 120 °C
The above diagram clearly indicates that the maximum permissible differential pressure is
Δpmax → 200 kPa (2 bar) at a nearly closed ball valve.
Note on chilled water applications
To prevent cavitation in chilled water circuits, sufficient counter pressure must be supplied to
the ball valve outlet, e.g. using an additional butterfly valve downstream of the ball valve.
Maximum permissible differential pressure over the ball valve: See 80 °C curve in the above
diagram.

Delivery
Ball valves, rotary actuators, and mounting kits are not assembled and are delivered in
individual packaging.
Applications with auxiliary functions
A standard actuator with corresponding functionality can be used if a ball valve application
requires a rotary actuator with auxiliary functions (e.g. auxiliary switch or potentiometer). In
this case, mounting kit ASK77.x is required in addition to the rotary actuator.
Follow the mounting instructions when mounting.

Notes
Safety
DANGER
There is a risk to operating personnel and device when working on the unit
Failure to comply with these safety notes can result in personal injury and damage to
property from pipe pressure, electrical voltage, or device in operation.
Note the following when servicing a ball valve/rotary actuator:
●Switch off both pump and operating voltage.
●Close shutoff valves.
●Release pressure in the pipes and allow them to cool down completely.
●Disconnect electrical connections from the terminals as needed.
●The rotary actuator must be properly installed prior to recommissioning the ball valve.
CAUTION
National safety regulations
Failure to comply with national safety regulations may result in personal injury and property
damage.
●Observe national provisions and comply with the appropriate safety regulations.
Engineering
We recommend installing the ball valve with spring return since temperatures are lower on
heating plants which increases the lifespan of the sealing gland on the stem.
Ensure there is no cavitation (see Section Technical design [➙2]).
A filter must be installed upstream of the ball valve to increase functional safety.
Permissible media
Using the ball valve together with potassium formate-based media can result in leakage over
the stem to the outside. The reason is the high level of penetration at low surface tension of
media based on potassium formate.
Siemens rejects any and all liability for damages or consequential damages resulting from
the use of this media together with our ball valves.
Mounting
It is easy to assemble the ball valve and rotary actuator; it can be done at the construction
site. No special tools or settings required.
Ball valve VAI60.. / VBI60.. is supplied together with mounting instructions M4213
(74°319°0883°0).

Pipe connection
Avoid leakage:
●Install fittings as per ISO 7-1. Ball valves (internal threading) = "Rp";
Piping (external threading) = "R".
●Do not use too much hemp or PTFE tape.
●Do not tighten pipe threading to the very end.
●Place the pliers/wrench on the ball valve union nut that is closer to the pipe to be
tightened or loosened.
Flow direction
Make sure that the valve is mounted in the proper flow direction. A symbol is applied to the
