Stafsjö’s standard double-acting pneumatic cylinder type SC is manufactured by 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 SC cylinder has a hard anodized aluminium barrel with coated aluminium caps, hold together by stainless steel tie rods to enable a long-term linear operation independent of position. The SC also includes several internal and external precision supports to further guarantee the linear stroke. A piston rod wiper at the bottom end cap ensures that no material enters the cylinder.
The supply pressure for the cylinder should be max 10 bar and the compressed air should be dry or slightly oil misted. Temperature range for the actuator is -30 to +100 °C.
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).
