Shut-off and control of the highest quality
The company OHL Gutermuth emerged from the firms OHL (formerly in Limburg, founded 1867)
and Gutermuth (formerly in Frankfurt, founded 1923).
Control and shut off-valves from OHL Gutermuth are the right choice when it comes to
regulating the flow of gases, vapours, liquids and granulates in a safe and economic way.
Decades of experience in the development and manufacture of industrial valves ensure that
the customer will receive a product that has been specifically designed and built to satisfy his
requirements. Personal discussion with the customer is first and foremost to our endeavours.
Convincing Technology and highest quality are important factors that allow us to fulfill the
quality management requirements of ISO 9001:2008 and the Pressure Equipment Directive
PED 97/23/EC Module H as certified by the German TÜV. The results of our commitment are
demonstrated by great customer satisfaction and long term business relationships.
The customer’s wishes and the solution required by his problem are the starting point of any
production. OHL Gutermuth has several decades of experience in the development and
production of industrial valves offering the customer the reliability he needs in his application.

CAM/CCM/CDM DEVELOPMENT… …APPLICATION
The models CAM, CCM, CDM (formerly BBOO, CCOO) OHL Gutermuth valves are specified and accepted INERNATIONALLY, as the ultimate in reactor
switching valves for sulphur tail gas clean-up processes. Literally dozens of CLAUS plants, world wide, using Sulfreen, MRCA and CBA processes, among
others, have OHL Gutermuth switching valves in their systems. We offer an exeptionally rugged valve – a valve with a different concept – providing an
extremely low leakage rate, with a minimum pressure drop, as well as superb reliability.
The valves in nominal sizes ranging from 1“ through 18“ are cast steel. Sizes from 20“ through 80“ are fabricated. Typical material specifications for
these valves used in relative conventional applications with a maximum temperature limit of 750°F (400°C) are as follows;
Valves are also available without steam jacket for other applications.

In the early 1970’s a new process for de-sulphurizing natural gas, was jointly developed by SNEA
of France, and Lurgi of Germany. The process, „SULFREEN“ was initially tried out at a location
near Lacq in France.
The reactor switching valves were to be rugged, metal seated units, with jackets for heating or
cooling the process, and, were to be in effect, bubble tight when closed.
OHL Gutermuth developed the valves for the prototype plant; from this successful beginning, the
world famous CAM, CCM and CDM valves evolved and are now available in sizes ranging from
2“ (50 mm) through 80“ (2.000 mm).

CAM/CCM/CDM …ORIENTATIONTYPICAL DIMENSIONS…
Typical mounting arrangement
Although vertical orientation is preferable, the valves will function as well in a horizontal position. Construction drawings for approval are always
provided to confirm the orientation by tag number, steam and condensate connections and locations, so that efficient heating and condensate drainage
are guaranteed. Universal steam connections can be provided to allow installation in either horizontal or vertical position.
Structural
Twisting moments and all maximum moments cannot be accurately predicted mathematically. Ideally, the valve should be installed so that it is free from
tension. Care must be taken so that only slight „bolting“ is required when installing into the line. Optimum function and tight sealing will result from
careful installation. Simply, consider the valve as a low pressure, light weight vessel; do not hang piping on the valve – support piping near the valve.
The following twisting / bending moments must not be exceeded:

CAM/CCM/CDM …FINITE ELEMENT ANALYSISPURGING AND LUBRICATION …
>> Lubrication
Some customers like to use these connections for lubricating. We do not recommend to apply any grease to the packing
or bearing. Thus packing material is pure graphite and the bearing is made from surface hardened stainless steel, we
don’t need that.
If you decide to apply any grease please take care that the grease doesn’t bake to the shaft. This might cause serious
sticking effects.
Finite element analysis
Comprehensive calculations on a 42“ angle valve using finite element analysis were used
as an aid to specifying maximum permissible pipe forces without adversely affecting the
functioning of the valve and it’s tightness in the seat.
Purging and lubricating connections on the valve bonnet
The valves are supplied with a double packing as a standard.
Between both packings it’s possible to apply nitrogen to monitor tightness of the packing
permanently. When checking the flow or the pressure drop of the connected nitrogen line,
an error in packing tightness will be recognized immediately.
Below the stuffing box and above the bearing we have a purge steam connection. This should
be used to keep the shaft and the bearing clean from sulphur build-up. Steam volume and
pressure are to be high enough to prevent sulphur gas from entering the stuffing box but
not excessive as to interfere with the process.

Stress-strain measurement by TÜV
Owing to the specific geometry of the valve body and the heating jacket, strength calculations to be
carried out in accordance with the pertinent technical codes will be very difficult and may lead to
unacceptable component dimensions. In order to demonstrate the permissibility of the dimensions
determined or selected, comprehensive stress-strain measurements were carried out. The stress-
strain measurements were carried out in cooperation with the State Material Testing Institute in
Darmstadt, the engineers of OHL Gutermuth and the independent experts of TÜV.
The evaluation of the results of the measurements on a DN 50“ valve with heating jacket provided
the experimental proof of sufficient strength at ambient temperature up to a test pressure in the heating
jacket of 22.9 bar. Up to this test pressure it can be stated that all comparative stresses determined are
clearly below the yield point of the material.
Required information for proposals
When requesting a proposal for OHL Gutermuth valves for switching applications, it will help us provide
a firm proposal quickly if the following information is provided:
1. Pressure Tests Components to be tested Test Pressure
Shell 150% cold pressure rating

Pneumatic Operator 100% cold pressure rating
Seat Closure (leakage) leak rates at operating pressure
2. Visual Examination n Markings (tags) as specified n Seat ring surface (body and disc)
n Identification plate n Surface quality of forgings
n Packing type, size, and number of rings n Orientation of steam connections
3. Dimensional Examination n Face to face dimensional examination n Quality of bolting threads
n Flange dimensions and orientation of bolt holes n Body and jacket thickness
n Facing finish of flanges n Stem diameter, surface finish, and straightness
4. Material Tests n The results of chemical composition and mechanical properties will normally be provided from mill test reports.
n Pressure containing welds of the shell will be 100% examined by dye-penetrant of all joints on the process stream
side and the outer longitudinal seams of the steam jacket.
n US-test of flanges
n Hardness-test of welds and heat affected zones acc. to NACE Requirements
n X-Ray on request
