Red Point®
Non-Contact Rising Stem Ball Valve
Red Point’s® Non-Contact Rising Stem Ball Valve (RSBV) is specifically engineered with friction-free sealing. It achieves this by detaching the ball from the seat through linear movement before rotation, resulting in reduced wear and tear and long-term sealing performance with minimal maintenance.
The valve’s non-contact ball movement, combined with the single-seated design, allows for a broad operating temperature range from minus 196°C up to 450°C.
The distinct quarter-turn helix-shaped stem mechanism is fully enclosed within the valve body, providing comprehensive protection against environmental factors and reducing maintenance.
