High pressure valve for system for high-pressure treatment of products, has valve stem tip sealing conical surface of counter bore of valve seat to bore of valve seat in closed state of high pressure valve

摘要

The valve has body (1) having an inlet (2) and an outlet (3). A valve seat (4) is arranged between the inlet and the outlet. A bore is arranged within the valve seat. A valve stem tip (6) has a tapered end and a cylindrical shaft. The valve seat faces the valve stem tip. The bore extends to the inlet of the valve seat. The valve stem tip seals a conical surface of a counter bore of the valve seat to the bore of the valve seat in a closed state of the high pressure valve. A cylindrical part of a lowering hole is designed as a cone at an angle of 6 degrees.
