Low Pressure Link Clamps

Double Acting

Available in three sizes: 550 lbs to 2,200 lbs capacities at 1,000 psi.
Excellent alternative to swing clamps when swing space is limited.
Left, forward, or right lever position from the same body.
Link clamps clear large obstructions better than other types of clamps.
Top Flange body mount.
Fluorocarbon seals available.
Flexible plumbing options accommodate either manifold mounting or SAE (face seal 39-0510-25 included).
Levers sold separately.
Optional In-Port Flow Control is a meter-in device with reverse free flow check valve.
Optional In-Port Sequence valve is a sequencing device with reverse free flow check valve.

* Clamp capacities are listed at 1,000 psi maximum operating pressure with a standard length link clamp lever installed.
** Equal to +/- 3° with standard lever.
*** Use of extended length levers will result in a reduction of clamp capacity. See graphs of lever output curves for clamping force of various lever lengths. Minimum operating pressure is 150 psi for double acting devices. The clamping force is adjustable by varying the hydraulic system pressure. To determine the approximate output force for your application, divide the clamp capacity shown above by 1,000 and multiply the resultant number by your system operating pressure to obtain the approximate clamping force for your application. (Actual force will vary slightly due to mechanical inefficiencies and friction.)
**** To insure maximum service life and trouble-free operation, restrict fluid flow to the above flow ratings when clamping. If you are unable to measure flow rates, the devices should be positioned in no less than 1/2 second. These recommendations apply when using the standard lever. When using the optional long lever or your custom lever, please restrict the flow rates to position the arm in no less than 1 second.
***** In-Port Valves require the use of manifold mount ports.
