What Is a Ball Valve & How Does It Work?

Ball valves are quarter-turn valves that control flow using a rotating ball with a drilled port. Known for their tight shutoff, fast operation and low maintenance requirements, ball valves are widely used in applications where dependable on/off control is necessary.

Gemini Valve manufactures a wide selection of ball valve configurations, including manual, pneumatic-actuated and electric-actuated designs. Our valves are available in multiple materials — such as brass, stainless steel and carbon steel — with a variety of sizes, pressure ratings and connection types to support diverse system requirements.

Our range of products includes compact mini ball valves as well as automated ball valves for process control and OEM equipment. All configurations are assembled and tested in-house to ensure consistent performance and application readiness.
