Plungers stay retracted during part loading. Hydraulic pressure advances the plunger exerting only spring force as it makes contact with the part. Hydraulic pressure then automatically sequences, "freezing" the plunger, to properly support the part. Available in 1,000, 2000, 4000 and 8,000 lb. capacity. Order with base or cartridge only. Ventless configuration and built in wipers protect the plunger movement from chips and debris. Four bolt base is compatible with Vektek in port flow control and in port sequence valves. Uses Vektek’s BHC technology to guard against corrosion. O-ring face seal design makes machining cavities easier.

 Standard SAE porting and alternate o-ring manifold face seal is located in the base of the support for bolt down installation. The base can be removed for direct cartridge mounting.
