Bare Stem Ball Valve

A bare stem ball valve is a quarter-turn rotary isolation valve supplied without a handlever, gear, or actuator, leaving the top drive stem completely exposed for tailored automation. Designed with an integrated ISO 5211 actuator mounting pad, this configuration allows system integrators to mount pneumatic cylinders, electric motors, or hydraulic operators directly onto the valve body post-procurement. Conforming to core standards like API 6D and ASME B16.34, this setup minimizes physical space requirements and reduces upfront equipment costs. It is an ideal baseline component for automated process loops, remote midstream pipeline headers, and skid-mounted fluid distribution systems. Automation integration facilities and plant piping contractors can optimize actuation budgets and streamline custom automated configurations by importing certified bare stem ball valves directly from premier manufacturers in China via our advanced B2B digital marketplace.
