Concentric Segmental Ball Valve
Concentric type V-notch segmental control valves contain valves, actuators, and other accessories. The ball has a special V notch, which affects the shear function with the seat while the ball rotates 90° in the body.
Concentric type V-notch segmental control valves contain valves, actuators, and other accessories. The ball has a special V notch, which affects the shear function with the seat while the ball rotates 90° in the body. This valve has good control and cutoff performance. We offer metal sealing and soft sealing types, adapting pneumatic actuators, positioners, solenoid valves, and other accessories. The valve is appropriate for throttling the service fluids containing strong acid, alkali, and oxidants, such as hydrochloric acid, sulfuric acid, hydrofluoric acid, nitric acid, and aqua regia.
