Further details for you 
In the case of ball valves without bearings, the ball floats between the ball seals. Absolute tightness is guaranteed in a vacuum, at low pressure and at high pressure due to the inherently elastic preload of the ball seals.
These ball valves are specially constructed and designed for hydraulic applications. They are characterized by their maintenance-free operation and long service life. Applications up to 200 °C and 500 bar operating pressure are possible at any time. The impact-resistant, high-quality aluminum handle ensures easy operation.
