Threaded Ball Valve

Threaded ball valves are shut-off valve that uses a 90-degree turn of a perforated ball to start or stop flow. Common designs include one‑piece, two‑piece, and three‑piece.
Specific Applications
Threaded ball valves are widely used in natural gas, petrochemical, oil refining, pharmaceutical, food processing, water treatment, HVAC circulation, and general industrial fluid systems. Depending on body and seat materials, they handle corrosive media, low‑temperature fluids, and even mildly abrasive slurries.
Key Features
Female Thread Convenience – Precision internal threads (NPT, BSPT, or custom) allow easy screw‑on connection to externally threaded pipes. No welding, no flanges. Our female threaded ball valves simplify installation and removal.
Custom Screw End Flexibility – Tailor thread types, lengths, and materials to your specific pipeline. Custom screw-end ball valves from our company fit any standard (DIN, ANSI, JIS, BS, GB).
Proven threaded ball valve design – Quarter‑turn floating ball with soft seats (PTFE, RPTFE, PPL, nylon) provides bubble‑tight shut‑off and low torque. Blowout‑proof stem for safety.
Wide Application Range – Natural gas, petrochemical, oil refining, pharmaceutical, food, water treatment, HVAC, and general industry. Handles corrosive media, low‑temperature fluids, and mild slurries. Temperature -40°C to 300°C, pressure PN1.6–6.4 MPa (Class150–300).
Customizable & Tested – Bodies: carbon steel, stainless steel 304/316, brass, or alloy. Actuation: manual lever, gear, pneumatic, or electric. End connections: threaded, flanged, or welded. As a reliable threaded ball valve, it undergoes factory high‑pressure, gas‑tight, and sealing tests before shipment.
Quality Certification
We hold ISO 9001, ISO 14001, and ISO 45001 certifications, plus a special equipment production license (TS). Our products are made to API, ANSI, JIS, ISO, BS, JB, and GB standards. This covers material checks, non‑destructive testing, precise measurements, and valve strength/sealing performance.
Custom Manufacturing Services
You send us a drawing or sample, and we review the requirements. Then we confirm the drawing and give you a quote — faster if you provide a 3D model. After order confirmation, we schedule batch production.
