Heavy duty, industry proven. The six and seven position cylinders are medium duty pneumatic positioning devices that operate through six or seven pre-determined positions of 1/2” (12.7 mm) increments with total strokes of 2-1/2” (63.5 mm) or 3” (76.2 mm) respectively. They were primarily designed for power-shift transmissions, but may also be utilized for indexing and any other application where fixed stroke increments are required. The ideal companion valve for these cylinders is AVENTICS “P” Rotair® six or seven position valve. An alternative control is an electro-pneumatic switching circuit using 3-way solenoid valves. These cylinders are extremely rugged, having anodized, corrosion-resistant, lightweight aluminum body, pistons and piston stops. Seals are a Teflon coated nitrile compound.
