Why do the Hydraulic Stud Tensioners Have Dual Hydraulic Ports?
Most of HTI’s Hydraulic Stud Tensioners have Dual Hydraulic Ports, even though they are single-acting because Dual Ports simplify the Hydraulic Hose connections. Typically, a longer Hose (15’ or 5m) connects from the Hydraulic Pump to the first Tensioner. Additional Hydraulic Hoses interconnect the Hydraulic Stud Tensioners in series, or “daisy-chained”.
Hydraulic Hoses have rated working pressures consistent with the working pressure of the Hydraulic Stud Tensioner and are available at any length. They are supplied with Hydraulic Quick-Disconnect (QD) Fittings and are pre-charged with hydraulic oil.
Would I ever need a single port?
For some applications, it is more convenient or faster to connect the Tensioner in parallel. In these cases, HTI can supply the Hydraulic Stud Tensioner with a single port and QD fitting. The Tensioners are interconnected using either Hydraulic Hoses with Tees, for series connection, or with a distribution block for parallel connection.
