GLOBE CONTROL VALVETYPE 3241

SMART IN FLOW CONTROLSAMSON – OUR EXPERTISE
Engineered Solutions From a Single Source
Combined with valve accessories, control valves serve as engineered solutions for many process controlapplications. SAMSON has been developing and manufacturing high-quality valves, actuators and valve
accessories for over 100 years. Our experience and expertise allows us to continuously develop ourproducts to provide a complete solution for your application.

Economical Total Cost of Ownership
The modular design of our products allows for a tailor-made solution while utilizing readily available
components. Furthermore, the interchangeability of spare parts between different valve models and sizes
contributes to low inventory management and costs.

Thanks to the combination of our trusted engineering and modular design, SAMSON can offer long-lasting
equipment, as well as reduced capital and operating costs.

Noise Reduction – When notgetting noticed is a good thing

Bellows Seal –Nothing left to chance

A flow divider is an optional internal device
used with gases and vapors to help reduce
the sound pressure level (SPL) of a valve.
By creating an additional stage of pressure
reduction inside the valve, it breaks a single
large flow stream into multiple smaller flow
streams, resulting in reduced noise emissions.

Many plants rely on toxic or
highly reactive compounds
for their processes, thesecompounds can present an
inherent health and/or safety
hazard and must be contained.
SAMSON’s bellows sealtechnology is the leader indesign and performance.

Three versions of flow dividers are available,
based on the amount of noise reduction
required. Depending on flow conditions, noise
reductions of up to 30 dB(A) can be achieved.

The bellows seal helps
ensure fugitive emissions arecontained and leaks to theatmosphere are minimized
down to near zero levels.

SPECIAL APPLICATIONS
Steam Service

Toxic and Corrosive Processes

Steam is commonly used in many plants andprocesses, it can however be very hard on
industrial equipment. The ability to prolong
the service life of valve internals in these harshconditions is crucial to reducing costs andincreasing plant productivity.

SAMSON valves are trusted in some of
the world’s most toxic and hazardousapplications. From Phosgene to Hydrofluoric
Acid, the 3241 can be customized to overcome
the challenges of corrosive applications.

At SAMSON, we use various hardening techniques
to combat these severe service applications.
By making use of metal hardening, tungsten
carbide, and ceramics, we are able to provide avariety of solutions to resist wear from theseprocesses. The result is an increased valve life
and a reduced total cost of ownership.

Monel, Hastelloy, Inconel, Titanium,Zirconium, Tantalum… No matter the process
requirements, the 3241 valve can be built toyour specifications.

Applications involving high purity gases suchas liquid nitrogen require a valve that cankeep it’s cool under demanding conditions,the 3241 valve is up tothe task for controllingthese processes.
When equipped withan extension bonnet,
the valve is capableof operation down to-325°F (-198°C). A metal
bellows seal can also
be provided in thesecryogenic applications
when required.
