Actuator
Doubleacting
The actuator type A-DA is a double-acting piston actuator for rotary motion. It is specially designed to meet the torque requirements for ball
segment, ball and butterfly valves. The patented backlash free connection to the valve shaft offers the best possible solution to optimise
control performance. With torque figures up to 20 000 Nm it covers the complete range of SOMAS valves. The actuator has ISO-connection to
the valve and connection according to VDE/VDI 3845 to the accessories. Stainless steel screws, rods and nuts as standard.
Bus communication On/Off application
SOMAS offers bus communication with AS-i interface for On/Off application. This solution reduces wiring time and cost and increases
flexibility to the end-user. SOMAS take full responsibility for function, assembly and testing.
Actuator
Springreturn
The single acting type A-SC has a spring to close function while the type A-SO has a spring to open function. Both types are built on the same
principle as the double acting type and completed with a spring package to achieve the desired function. The spring is built into a package to
secure safe maintenance. The other features mentioned above for the double acting type are also valid for the single acting types.
Locking device and manual override are available as additional equipments for the SOMAS actuators type A.
Bus communication Control application
SOMAS supplies digital positioner with Profibus PA or Foundation Fieldbus from leading manufactures so that we can meet your specification,
and fully integrate into existing systems. SOMAS assembles and tests the function. If there are special needs for configuration/set up we can
configure this before despatch.
Positioner
The pneumatic positioner type SP405
is designed for a pneumatic input signal 20 - 100 kPa (3 - 15 psi) or split-range. The positioner is as standard equipped with a linear cam and as an
alternative with a cam that gives an equal percentage characteristic. It offers high flow capacity and easy adjustment of span and zero.
The electro pneumatic positioner type SPE405
is built on the pneumatic version type SP405, which has been completed with an I/P-converter. This I/P-converter is located in a separate
housing which is connected to the pneumatic part. Capacity and adjustment as per type SP405 and an input signal 4-20 mA.
Positioner
Digital
Positioner
SOMAS offers intelligent control solutions by using valves and actuators of own design in combination with digital positioners from leading suppliers.
We take full responsibility for function, assembly and testing. Out flexibility offers the most “state-of-the-art” solutions for all
demanding applications within all types of branches.
The valve can be equipped with different types of manual actuators such as hand lever and gear unit and accessories such as mechanical
switches and proximity switches depending on the application.
Hand levers and gear units can be equipped with locking device.

SOMSIZE – The SOMAS valve sizing program
By using SOMSIZE you will easily find the right type of valve and the right
size for your application.
SOMSIZE is a windows based program.
Formulas for flow calculations are according to EN 60534-02-1
and noise calculations are according to VDMA 24422.
Beside the valve sizing you can also have a valve specification complete
with actuator and accessories along with main valve dimensions.
Contact SOMAS or our representatives
for further information.
