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