Product description

With the use of the Rötelmann sandwich-plate, which is bolted separately to the control block, all the channels through the plate can be blocked and the directional-control valve can be replaced without having to depressurize or drain lines and without affecting the other control units on the same block. All channels are open during normal operation. The operating handle can be removed to prevent unauthorized actuation.

- full bore design causes no pressure drop
- significant reduction in hydraulic system downtime
- no need to drain fluid, bleed air or refill the system
- simplified start-up and maintenance due to the ease of changing flushing
plates and directional valves
- pressure can be maintained in cylinders so that the supported loads do
not need to be shored up
- standard mounting and porting patterns allow retrofit without rework
- proprietary design increases safety by utilizing separate mechanically
isolated bolts for mounting the sandwich-plate and directional valve;
removing the directional valve cannot accidentally loosen the sandwichplate
