1. INTRODUCTION
This manual is intended as a guide to assist customers
in the installation, and maintenance of WIKA instruments

Installation and Operation Manual (IOM) carefully and
make sure you understand everything.
If in doubt, please consult with WIKA Instruments Italia’s
technical dept.
WARNINGS & SAFETY
INSTRUCTIONS
WIKA instruments Monoblock Ball Valves must only
be used, installed, and repaired in accordance with
these instructions.
In the event of leakage or other malfunction, please
contact a qualified service person, as a continued
operation may cause system failure or a general
hazard.
Keep hands and objects away from the valve ports at
all times.
Before removing a valve from the line, always make
sure the line has been depressurized and drained.
Cycle the valve a few times to relieve any pressure
that could be trapped in the body cavity.
Always wear Personal Protective Devices when
handling a valve especially with toxic, flammable or
corrosive fluids.
Do not operate valves with visible leaks: valves have
to be isolated and repaired.
Valve surface temperature may become extremely
hot or cold due to operating conditions. Avoid any type
of direct contact with the valve that may cause harm
or injury.
The valves should be used in a well-designed,
adequately supported piping system in order not to be
subjected to undue forces, stresses or shock loads
during service.
The system should be adequately protected to ensure
that external and internal pressure and temperature
limits do not exceed the valve limits.
Never look into the valve bore while the valve is in a
flow line. Pressure and fluids could escape from the
valve causing harm or injury.
The Monoblock ball valves are fit to be used
completely open or completely closed: therefore they
shall not be used for flow lamination.
Monoblock ball valves are not designed to undergo
full ∆P. Monoblock ball valves shall be operated with
maximum 4bar (60psi) ∆P.
Always use WIKA original spare parts.
