Stafsjö will shortly introduce a new double-acting pneumatic cylinder manufactured 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.
The SC cylinder has a hard anodized aluminium barrel with coated aluminium caps, held strongly together by stainless steel tie rods to enable a long-term linear operation independent of position. The SC also include several internal and extended precision supports to further guarantee the linear stroke. A piston rod wiper in bottom end cap ensure that no material enter the cylinder.
The SC cylinder is CE marked and also approved for use in EX areas according directive 2014/34/EU Group II category 2G/2D (zone 1 or 21).
