ASTM A216 WCB butterfly control valves, crafted from carbon steel alloy, boast the material’s strength, toughness, and corrosion resistance. These rotary control valves regulate gas or liquid flow by rotating a disc 90 degrees to control the passage size. Equipped with pneumatic or electric actuators, they provide rapid shut-off, precise regulation, and remote control, enhancing efficiency and responsiveness in various piping systems.
