Annular Ported Cylinders

Delta designs and manufactures annular ported double acting feed cylinders in both telescopic and rod designs. The types of cylinders incorporate ported inner cylinder walls, which enable the flow of hydraulic fluids that power the pistons to flow internally within the cylinder without the need for external hoses and tubing.

Annular ported cylinders are used in reliability critical applications where the operating environment could expose external hoses and tubes to physical damage, fire or chemical damage, or in applications where there is no space for external hoses and tubes.
