Pulp mills


Somas has developed and manufactured valves since the late 1950’s. Back then the sole focus was on valves and other equipment specifically designed for the pulp and paper industry. Altogether, this field and our cooperation with its clients have been very important for us. It has helped and largely shaped Somas traditional valve program, characterized by the acid-proof stainless steel in all wetted parts.

PULP Mills

Pulp mills offer a wide range of different application-areas that are excellent for Somas valves including (but not limited to) blow-valves, valves for air circulations, valves for pulp-flows while straining or bleaching. Many areas of application require special valve materials able to handle the corrosive environment. Somas has solutions for your specific needs, both in terms of design and materials. Pulp mills utilize recycling-systems for various boiling chemicals which also require high-performance valves. There are several other areas in a pulp mill where you could benefit from using Somas valves, including drain control and water supply. 

how somas valves can be used

Somas different valve types, – ball segment, butterfly and ball valve – are all used on paper machines. The valves can be used as control valves, on/off valves or manual hand valves. It is a given for us that all our products can handle the different process requirements. Therefore, we manufacture all our valves using stainless materials as standard. We can however deliver valves made of titanium or high-nickel-alloys if you require.

Our actuators consist of surface-treated aluminum and stainless steel in order for them be able to to handle the type of environment they are installed in.  These materials make SOMAS actuators well equipped to handle the requirements set by the pulp and paper industry. The actuators unique ability to achieve maximum momentum in either open or closed positions guarantees the security required during use.


SomBook® is a tool where we have collected our many years of experience about valve options, material options as well as other important information about the valves we suggest for specific applications.
