Neway Ball Valves – Floating & Trunnion Mounted
Our floating and trunnion-mounted ball valves are precision-engineered to ISO 17292, API 608, and API 6D standards. Constructed for reliability in refinery, chemical, LNG, pipeline, and power service, these valves offer soft and metal seat options. Available sizes and pressure classes.
Design Features & Core Benefits
High-Performance Soft & Metal Seats
Soft and metal seat options provide tight shutoff, fire-safe performance and long life across the full ASME pressure range.
Full-Bore or Reduced-Bore Flow
Available in full-bore and reduced-bore designs to balance flow capacity, pressure drop and weight for each application.
Fire-Safe, Anti-Static & Stem Safety
Fire-safe certification (API 607 / API 6FA), anti-static design and blowout-proof stem support safe operation in critical services.
Wide Temperature & Media Coverage
Floating and trunnion-mounted designs cover -196°C to 650°C with carbon steel, stainless and nickel alloy bodies for a wide range of fluids.
Flexible Actuation & Control
Manual, gearbox, pneumatic, electric and electro-hydraulic actuation options support on/off and emergency shutdown duties.
DBB & Pipeline Solutions
Trunnion-mounted, fully-welded and DBB compact manifold ball valves provide double block and bleed and space-saving pipeline solutions.
