A hydraulic seat and holding valve for hydraulically controlling and holding a hydraulic load in a leakproof manner comprises a seat pairing, whose valve cone, which is part of the piston, is capable of adapting itself to the conical valve seat. To this end, the valve piston is supported for pivoting relative to the valve seat. The cone angles of the valve cone and the valve seat are different.
1. A hydraulic seat and holding valve for hydraulically controlling and for holding a hydraulic load, the valve comprising:a valve housing at least partially defining a first chamber and a second chamber, and comprising a generally conical valve seat positioned between the first chamber and the second chamber; a valve piston which is positioned in the valve housing and has a generally conical circumference, with the conical circumference of the valve piston and the valve seat functioning together as a seat pairing for closing the first chamber relative t...
