ACTUATORS

SOMAS actuator type A is developed for control and on / off applications. 
The actuators are primarily adapted to SOMAS ball valves, calotte valves and butterfly valves.

Actuators type A-DA are double-acting and developed for SOMAS valve range where the torque requirement is greater. Therefore, we have placed great emphasis on low friction and freedom of play. Due to the fact that there is no gap between the actuators and the valve, the control function becomes optimal. 

Single acting actuators type A-SC / SO are basically constructed in the same way as the A-DA device, with the difference that there is a built-in closing or opening spring function.

BALL VALVES

Leakage of gases and liquids should be prevented at all costs. SOMA's ball valve is made to handle this and is designed for shutdown of liquids and gases. Our ball valve is a full-flanged valve with cylindrical passage in the dimension range DN25 - DN500.

BUTTERFLY VALVES

The SOMA butterfly valve will help you regulate your flow, whether it be steam, gas, water or other liquids. The valves are made of stainless steel with a homogeneous metal seat. Installation is done via clamping between flanges both with and without lugs.

CHECK VALVES

Liquid, steam or gas - SOMAS damper back valve fits all three. The valve is developed and adapted for clamping between flanges. The damper check valve is of two types, with or without spring, and is made of stainless steel to meet the process requirements set.

CONTROL VALVES

Control valves have a central position in SOMAS valve program and can be used in many areas and industries. Several of SOMAS valves are used as control valves, where the calotte valve is one of them. Thanks to its design, with a single piece caliper and spindle, the calotte valve has the optimum control properties. The butterfly valve is also an excellent control valve. The ball valve has a characteristic that is less suitable for regulation, but since the other advantages of the ball valve (valve seats in both directions and low resistance at full opening) are important, it can very well be used as a control valve.
