Further technical information Actuators and accessories

Technical data for the materials used in the SOMAS valves, flange standard, steam data, etc. can be found in section 6 of the SOMAS catalogue. The valves can be fitted with SOMAS manual, on/off or control actuators in accordance with the selection table above. The valves will then be delivered as tested shut- off or control units ready for installation. Check sections 4 and 5 of the SOMAS catalogue, where positions, limit switches and solenoid valves are also presented. We can also fit other types of actuators and accessories in accordance with your specification.
