Page 4 of BB Gate Valve

A BB Gate Valve, or Bolted Bonnet Gate Valve, is a type of valve designed for controlling the flow of fluids by lifting a gate or barrier out of the fluid's path. The valve features a bonnet, which is securely attached to the valve body using bolts, nuts, and studs. This bolted bonnet design allows the bonnet to be removed for easy access to the stem and internal components during maintenance.
