Presenting a tougher environment than that of many other processes, with low pH values and abrasive media, the processing of food, slaughterhouse and kitchen waste at Linköping’s biogas plant generates two highly demanded products - biogas and bio-fertilizer. We are talking about the achievement of a sustainable society in practice.

Linak’s electric actuator is a compact maintenance free unit for on/off operations with a speed 7-11 mm/sec. It is available as standard in a 24 V DC version but it can also work on 230 V AC or 120 V AC if it is supplied with a control unit/transformer. 

During first and second quarter 2018 Stafsjö will introduce a new double-acting pneumatic cylinder manufactured by our collegues at Ebro Armaturen. It is a solid construction designed for tough knife gate applications available from 100 mm (4”) up to 320 mm (12.6”) bore diameter. The interface to valve adapter and gate clevis is the same as for the EC cylinder.
