Vektek Low Pressure 7MPa Catalog

7 MPa Link Clamps

Link Clamp Specifications

Double Acting Rotary Lug  Patented rotary lug feature delivers 360° of lever positioning. Simply rotate the lug and lever over the desired clamping location and torque the set screws.  Maximum clamping force - Minimal footprint.  Available in five sizes ranging from 2.4 kN to 16 kN capacities at 7 MPa (70 bar).  Operate at any pressure without pressure reducing the clamp.  Excellent alternative to a swing clamp when swing space or hydraulic pressure is limited.  Top flange manifold mounted or plumbed using G 1/4, G 1/8, S-Series or L-Series fittings  Levers sold separately, see the start of Section F.  Link Clamp Levers and Work Supports are paired to clamp over centerline of work support. n Optional In The Port Flow Control is a meter-in device with reverse free flow check valve. n Optional In The Port Sequence Valve is a sequencing device with a reverse free flow check valve. (face seal Model No. 39-0510-87 and Model No. 39-0510-88 o-rings included)

* Clamp capacities are listed at 7 MPa (70 bar) operating pressure with a standard length 7 MPa link clamp lever installed. Use of an extended length lever will result in a reduction of clamp force. See section "F", for the clamping force of various lever lengths and pressures. The force is adjustable by varying the hydraulic system pressure. ** To insure maximum service life and trouble-free operation, restrict fluid flow to the above flow ratings. If you are unable to measure flow rates, these devices should be positioned in no less than 1/2 second. These recommendations apply when using the standard lever. When using the optional extended lever or your custom lever, please restrict the flow rates to position the lever in no less than 1 second. *** Equal to +/- 3˚ with standard lever **** In The Port valves require the use of manifold mount ports.

NOTE: Maximum operating pressure is 10 MPa (100 bar) Minimum operating pressure is 1 MPa (10 bar)
