Since its inception in 1966, Kämmer has been manufacturing application-specific and general-purpose control valves and actuators. Kämmer solutions are used extensively in the chemical, petrochemical, energy, petroleum, pulp and paper, pharmaceutical, food processing, and cryogenics industries.
Although more than half of all Kämmer valves are custom-designed, special applications often do not require additional time or cost due to the flexibility and interchangeability of Kämmer valve design.
Particular answers for challenging applications
Kämmer valves are designed to handle a wide range of operating conditions: pressures from vacuum to 4,137 bar (60,000 psi) and temperatures from -46°C to 427°C (-50°F to 800°F). Body materials include all standard stainless steels, plastics, and non-standard materials such as Monel®, titanium, Hastelloy®, or ceramics. Specialized Kämmer valves are available for cryogenic, high-pressure, corrosive, sanitary, low and micro-flow, severe duty, and other applications.
In addition to its standard product portfolio, Kämmer regularly develops mechanical solutions for low and micro flow applications, difficult laminar flow, and other complex technologies, such as:
Heavy-duty valves in severe use applications
Liquefied Natural Gas (LNG) Production
High-pressure valves in low-density polyethylene (LDPE) production
Industrial gas transportation
Tank outlet and injection valves

GENERAL SAFETY INFORMATION
The following instructions are designed to help
unpacking, installing, and performing maintenance as
required on Kämmer actuators. The users of the product and the
the maintenance staff should thoroughly study the present
bulletin before installation, operation, or execution
any maintenance on the actuator. Special
installation, operation, maintenance instructions
cover additional features (such as unique decorations,
handwheels, extension covers, etc.)
To avoid possible injury to personnel or damage to
of the actuator components, the WARNING and CAUTION notes must
must be strictly observed. Modification of this product,
the replacement of non-factory parts or the use of maintenance
procedures other than those described may affect drastically
affect performance and be hazardous to personnel
and equipment and may void existing warranties.
WARNING: Standard industrial safety practices must
must be observed when working on this or any other,
process control product. Specifically, the personal ones
protection and lifting must be used
Operations on these triggers may only be performed by
trained personnel using the appropriate tools.
When unpacking the activator, check the packing list
with the materials you received. The lists describing the
activator and accessories are included in each shipment
When lifting the actuator from the shipping container,
attach the lifting straps to avoid damage to the piping
and installed components. On the more significant triggers, pick him up
actuator using straps through yoke legs or if
provided lifting brackets bolted to bonnet bolts.
Warning: When lifting an actuator with hoists
with straps through the legs of the yoke, you must know that the center of its
gravity may be above the lifting point. Hence,
support must be provided to prevent the actuator from being removed
to rotate. Failure to do so may result in serious injury
to personnel or damage to the actuator and nearby
Please get in touch with your shipper
in case of shipping damage. In case any problem arises, call him
Please make sure you get proper head clearance for it
actuator so that the plug can be disassembled from the
from the valve body.
Connect the air supply and instrument signal (air or mA).
Lines. Throttle control valves are equipped with
a valve positioner. Two connections are noted: One for
the air supply and the other for the instrument signal.
Both the actuator and positioner are suitable for 4.2 bar
(60 psi) of air. The air regulator is not mandatory.
Unless the supply pressure exceeds 4.2 bar (60 psi). One
air cleaner must be fitted before the positioner unless
the supply air is immaculate and dry. All connections
must not leak.
CAUTION: On actuators equipped with air filters, the
the air filter must point down: otherwise, the air filter will
it will not work correctly.
Note: In some rare cases, the air supply must
be limited to less than 4.2 bar. In these cases, refer to
the type plate.
At least once every six months, check for correctness
operation following preventive maintenance
described below. These steps can be performed
while the valve is in line and, in some cases, without
stoppage of operation.
Inspect the actuator for corrosive damage
fumes or process droplets.
Clean the actuator and repaint the heavily oxidized areas.
Tap the actuator and check for smoothness
and full track mode. Unsteady stem movement can
indicate an internal problem.
Warning: Keep hands, hair, clothing, etc., far away
from all moving parts when operating the actuator.
Failure to do so may result in serious injury.
Make sure all fittings, brackets, and screws are
If possible, remove the air supply and observe the actuator for
for proper fail-safe operation.
Check the actuator for air leaks.
If an air filter is provided, check and replace the cartridge if
