Presentation

The clamping module type NSMD2 is intended for the actuation of hydraulic clamping devices, such as draw-in collets (hollow or massive) at CNC-lathes. Type NSMD2 is designed as manifold mounting valve featuring a hole pattern conforming DIN 24340-A6. All necessary functions to be per-formed e.g. clamping/releasing of the clamping cylinder, pressure reduction, and electric pressure monitoring (if requested) are housed in one body.

The adjustment of the clamping pressure and the pressure switch takes place via only one adjustment device either manually, with tools or electro-proportionally. This feature is available for consumer port A only or both A and B. A unique safety circuit monitors the mode of the 4/3- or 4/2-way directional valve. The actuation of these directional valves is usually with spring return but the 4/2-way is also available with detent. Additional functions e.g. throttling in the spool’s end position, rapid traverse and creeping for one or both consumer sides are possible. All this enables us to tailor a valve meeting exactly the requirement of the application.
