HYDRAULIC SNUBBERS AND SHOCK ABSORBERS

Snubbers allow free thermal movement of piping and equipment during normal operation.

 

When locked up by transient loads they provide resistance to movement, protecting your piping and equipment.

 

Anvil snubbers are velocity sensitive restraints for minimizing the movement of critical equipment and piping that if subjected to dynamic movements may cause catastrophic failure.

 

They are the seat belts of the piping system, providing controlled restraint during seismic and dynamic events, while allowing normal thermal movement.​

There are seven standard sizes with cylinder bores of 1 1⁄2” to 8” and with normal load ratings from 3,000 pounds to 128,000 pounds. All are available with 5”, 10”, 15”, or 20” strokes except the 1 1⁄2” size which is offered with 5” and 10” strokes only.


Snubbers are available with integral or remote reservoirs.

Features:

  • Valves are available as either temperature compensating or as adjustable

  • Available with pressurized, polycarbonate, or metal vented reservoirs

  • Continuous operation at 150° F with brief transients to 350° F

  • Factory calibrated valves

  • Rapid, positive valve closure

  • Special design minimizes the “lost motion” which results from the shifting and seating of piston seals

  • Unlocked resisting force is less than 17 1⁄2 pounds for sizes 1⁄4 and 1⁄2 Fig. 3306 and less than 2% of rated load for all other sizes

  • Stable non-flammable, long life hydraulic fluid

  • Self-aligning bushings permit ± 5° misalignment or angular motion. Bushings are coated with a dry lubricant.
