Gemini Valve designs and manufactures 2-way ball valves for quarter-turn shutoff in industrial and OEM systems. Built in the USA and supplied factory-direct, our valves provide consistent sealing performance and dependable mechanical operation across a wide range of controlled media applications.
Available in sizes from ¼” to 2”, our 2-way ball valves are offered in manual, pneumatic and electric configurations. Standard body materials include brass, 316 stainless steel and carbon steel to support diverse pressure, temperature and media compatibility requirements.
What Is a 2-Way Ball Valve?
A 2-way ball valve is the most commonly specified configuration for on/off flow control. Its two-port design allows media to pass directly through the valve body when open and provides positive shutoff when rotated 90 degrees to the closed position.
Because of this simple geometry, 2-way ball valves are widely selected for applications where full isolation is required and flow diversion is not needed.
When specifying a 2-way ball valve, engineers should evaluate:
- Media compatibility
- Maximum working pressure
- Allowable differential pressure
- Temperature range
- Required flow coefficient (Cv) and flow rate
- Thread type (NPT vs. BSP)
- Cycle frequency and actuation requirements
Careful alignment between these variables helps ensure consistent sealing, stable torque performance and predictable service life.
By concentrating on compact ball valve designs, Gemini prioritizes precision machining, actuator integration and practical manufacturability for OEM and industrial applications.
