Bolted Bonnet Plug Valve

A bolted bonnet plug valve is a robust quarter-turn rotary isolation valve featuring a heavy-duty bonnet securely fastened to the valve body with high-strength studs and a compression gasket. This bolted assembly provides excellent mechanical sealing, structural stability, and pressure containment while allowing straightforward inline access for maintenance, plug adjustment, or sleeve replacement. Conforming to design codes like API 599 and ASME B16.34, bolted bonnet plug valves are highly specified for handling abrasive slurries, corrosive chemicals, wastewater treatment loops, and high-velocity oil and gas lines. Piping layout designers and maintenance networks can optimize system uptime and simplify inline valve servicing by importing premium bolted bonnet plug valves directly from certified manufacturers in China through our advanced B2B platform.
