Design
The 2/2-way stainless steel ball valves of the VZBC series consist of:
– a housing with the corresponding piping connectors in a flange design
– a soft-sealed ball as sealing body,
– a switching shaft with switching-shaft seal and position indicator. The slot direc
tion on the shaft corresponds to the flow direction.
– a flange to ISO 5211 for manual or automatic control.
The product is available in various designs. These operating instructions describe
the following product variants:

Function
The rotation of the mounted semi-rotary drive or hand lever is transmitted to the
switching shaft of the ball valve.
The switching shaft transmits the rotation to the soft-
sealed ball. Depending on the switching position the
ball blocks or enables the flow. The ball valves VZBC
can be switched by 90° to the two positions “OPEN”
and “CLOSED”.

Application
As intended, the Ball valves of the series VZBC serve as a process valve for the flow
control of neutral, liquid and gaseous fluids in pipeline systems. The products are
tailored to the requirements of factory and process automation (
è
catalogue
www.festo.com/catalogue). They are suitable for use in the chemical and petro
chemical industries.
For special environmental conditions:
Observe the specifications on the product certificate
è
Support portal at
www.festo.com. When the device is used in dust-laden environments, surfaces
and actuators must be cleaned at regular intervals. The cleaning intervals de
pend on the amount of dust present and on the surface temperature generated
by the fluid.
The ball valves can be operated with an appropriate semi-rotary drive (flange to
ISO 5211) or hand lever.
– Operation with abrasive media and solids is impermissible.
– Before using the product, test the compatibility of the medium with the materi
als of the product in order to avoid damage to the medium (
è
Technical data).
– The VZBC ball valves can be used for fluids of Group 1 in accordance with EU
Pressure Equipment Directive.
– The VZBC ball valves are inappropriate for permanent intermediate positions
and for controlling the flow rate.
– Welding into a pipeline is impermissible. Use appropriate fittings to screw the
product to the pipeline.
