Brass Ball Control Valve

A brass ball control valve is a compact, cost-effective quarter-turn rotary valve equipped with a characterized internal disc or V-notch port, designed specifically for modulating hot/chilled water and low-pressure steam in commercial HVAC and hydronic automation systems. Cast or forged from corrosion-resistant brass (such as CW617N or DZR brass), this valve features low operating torque and self-lubricating PTFE seats that ensure smooth, reliable actuation over thousands of duty cycles. Conforming to standards like MSS SP-110 and EN 12165, these efficient control valves are standard specifications in air handling units (AHUs), fan coil units (FCUs), and municipal building heating systems, allowing HVAC contractors and building automation integrators to optimize energy efficiency by importing certified brass ball control valves directly from leading manufacturers in China via our advanced B2B commercial platform.
