Kämmer®

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 [1]Monel®, titanium, [2]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

guaranteed.

Operations on these triggers may only be performed by

trained personnel using the appropriate tools.

Unpacking

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

container.

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

equipment.

Please get in touch with your shipper

in case of shipping damage. In case any problem arises, call him

your representative.

Installation

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.

ACTUATOR MAINTENANCE

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

securely fastened.

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

it’s necessary.
