Double-acting pneumatic cylinder

July 2019 Valves, Actuators & Pump Control

Stafsjö’s standard double-acting type SC pneumatic cylinder is manufactured by Ebro Armaturen. It has a solid construction and is designed for tough knife gate applications from 100 up to 320 mm bore diameter. It has a hard anodised aluminium barrel with coated aluminium caps, held together by stainless steel tie rods to enable 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 10 bar maximum and the compressed air should be dry or slightly oil misted. The temperature range for the actuator is -30 to 100°C. The cylinder is CE marked and also approved for use in Ex areas according to directive 2014/34/EU Group II category 2G/2D (zone 1 or 21).

Assembly kit included for Stafsjö’s knife gate valves

Stainless steel adaptor and gate clevis kits are supplied assembled on the SC cylinder to make it easy to install on Stafsjö’s different knife gate valves.

Namur interface for direct assembly of solenoid valves

An integrated Namur interface according to VDI/VDE 3845 on the top cover enables direct assembly of the solenoid valves, which reduces piping efforts to a minimum.

Prepared for magnetic limit switches up to SC200

The SC is supplied as standard with a magnetic ring on the piston and an integrated T groove in the cylinder barrel up to SC200 for installation of magnetic limit switches according to ISO 15552.
