C1 Warning Instructions for Operation and Maintenance
C2 Automated Operation
A manually actuated valve is closed by turning a hand wheel in the clockwise direction and opened by
turning in the opposite direction.
A valve with drive actuation is operated using control signals. Valves that are supplied with a drive
from the factory are supplied in a correctly adjusted and configured manner. This configuration should
not be changed as long as the fitting works as intended.
Valves with rare actuation:
In order to maintain functionality of a valve, it should be actuated with a full stroke at least once a year.
C3 Maintenance
As long as the valve seals correctly, the only required maintenance is a visual check of the leak-
tightness of the housing in suitable intervals.
 The function of the fitting must correspond to the <Intended Use>, which is
described in Section A2.
 The operating conditions must match the information on the type plate of the valve,
see Section A3.
 Necessary work on the fitting itself may only be performed by specialist personnel.
Specialists in accordance with these instructions are persons that can
properly assess and implement the working operations they are entrusted
with due to their training, knowledge and professional experience and are
capable of recognizing and eliminating possible dangers.
 The valve should be checked periodically during operation to guarantee the
safety of the personnel. During maintenance or repair operations, the valve
must be deactivated as stated in Section B7: The pipe sections on either side
of the fitting must be depressurized and emptied prior to starting any work.
1. Actuation of a valve with drive is only permitted:

2. If a valve was installed as an end valve in a system section, a suitable safety
device must prevent access to the moving parts of the vale and protect the
personnel from escaping media.
Risk to life and limb of user in case of non-compliance. Every other use of the
