Three-Piece Internally Threaded Ball Valve

Three-piece ball valves offer multiple connections: internal threads, industrial heavy-wall welding, sanitary thin-wall butt welding, sanitary quick-connect, sanitary flanges, national standard flanges.

Three-piece ball valves use precision investment casting for compact structure. Spring-loaded seats ensure reliable sealing with low torque. Bottom-mounted stem design prevents blowout under overpressure.

Standard ISO top pads allow installation of pneumatic/electric actuators. Optional position feedback and smart positioners meet automation requirements.
