Ball segment valves

SOMAS ball segment valve is the optimal control valve. It is suitable for most business areas due to its high capacity and rustic design and is also service-friendly.

Butterfly valves

SOMAS butterfly valve requires virtually no maintenance. This is thanks to its unique design and the robust valve seat. It is suitable as both a control and on/off valve.

Ball valves

SOMAS ball valve with its two valve seats is most suitable as an on/off valve. Its full bore results in low flow resistance in the open position.

Check valves

SOMAS check valve has a a high capacity and short closing time. The valve is suitable for use in applications where fluids, steam and gases need to be handled.

control valves

Several SOMAS valves can be used as control valves. Thanks to its design and the connection between the valve and the actuator you get the optimal capabilities for precise and accurate control.

On/off valves

SOMAS offers several valves suitable for on/off applications.
The valve shuts off the flow without leakage and has a low flow resistance in open position. 

Manual valves

SOMAS has a number of valves that are suitable as manual valves where low flow resistance in the open position is an important factor.


SOMAS actuators are special. They have been specifically engineered to meet the process industry requirements for reliability and accuracy in regulation. The actuators are first and foremost intended for use with SOMAS valves, they can however easily be adapted for use with other valves demanding a 90 degree arc of operation.
We have eliminated any backlash between the moving parts of the actuator or between the actuator and the valve. This has created the neccessary prerequisites for pinpoint precision and enables accurate process diagnostics.

SOMAS also offer solutions in the form of manual actuators such as hand levers or gear units.

Pneumatic actuators type a

SOMAS pneumatic actuator type A is designed for control- and on/off applications. This actuator is primarily intended for use with SOMAS ball valves, ball segment valves and butterfly valves.

single acting

Developed for SOMAS valves where the need for torque smaller is. Single acting actuators come with a opening/closing spring function installed.

Double acting

Developed for SOMAS valves with a greater need for torque. Low friction and backlash-free connection are features which optimize the control performance.


SOMAS actuators can be equipped with all necessary accessories to achieve the desired functionality. Valve positioners are a common accessory for our control valves.


SOMAS valves offer 80 – 90 degrees of turning. However, in many systems it is not advisable to increase or decrease the flow too quickly.  For valve sizes larger than DN80 the use of hand lever should be considered very carefully. 

gear unit

A gear unit can be used on all valves in the SOMAS portfolio and is available in several different sizes. The unit has adjustable end-positions and a visual indicator for the current position of the valves.

hand lever

Hand levers can be used on all SOMAS valves. The hand levers have adjustable end-positions and can be locked in either open or closed positions.


SOMAS manual actuators can be equipped with various accessories such as a locking mechanism and limit switches. The locking device locks the valve in the chosen position.


When a valve needs to be operated remotely, or is used frequently, it needs to be fitted with some type of actuator. If you cannot find the actuator you need in our own product catalogue, we can also deliver actuators from other well-known manufacturers according to your wishes.


SOMAS actuators can be equipped with all necessary accessories to achive the desired functionality. Valve positioners SP405/SPE405 and TZID-C are the most common accessories for our control valves. There are also solenoid valves and limit switches for use with our on/off valves.

valve positioners

SOMAS pneumatic valve positioners are used with actuators that offer 90 degrees of turning. It can easily be fitted on SOMAS selection of actuators.

solenoid valves

Control of the air supply for on/off-applications is achieved with the help of  solenoid valves that are fitted directly on to the valve actuators.

limit switches

SOMAS offers a variety of different solutions that include micro switches and various types of inductive sensors.

other accessories

Beyond the accessories already mentioned there are also fitter-regulators, switch-boxes for limit-positioners and specially engineered solutions.
