Cast Iron Threaded Ball Valves

Detailed Information on Cast Threaded Ball Valves

Cast threaded ball valves provide an industrial solution resistant to high pressure, temperature, and mechanical loads thanks to their GG25 (cast iron), GGG40 (ductile iron), or carbon steel (WCB) body structures. While the full-bore spherical closing element creates low pressure loss, it ensures high sealing performance with PTFE or graphite gaskets.

Key Advantages

• • Cast body with high pressure resistance.
• • Easy installation with threaded connection.
• • Full-bore design for high flow rates and minimum loss.
• • Leak-proof performance with PTFE or graphite seals.
• • Body and stem structure with high mechanical strength.
• • Long-lasting use in industrial lines.
• • Suitable for medium and high-temperature applications.

Material Specifications

• • Body: GG25 (Grey cast iron), GGG40 (Ductile iron), WCB (Cast carbon steel)
• • Ball: Stainless steel or chrome-plated carbon steel
• • Seals/Gaskets: PTFE, RPTFE, or graphite
• • Stem: Stainless steel – blow-out proof
• • Connection: BSP or NPT thread
• • Coating: Epoxy paint / electrostatic application

Application Areas

• • Water and hot water lines
• • Oil and hydraulic lines
• • Compressor – compressed air systems
• • Chemical process lines
• • Steam and high-temperature applications
• • Industrial production and machinery lines
• • Fuel and solvent circuits
• • In-plant process control

Technical Capacities

Cast threaded ball valves are typically manufactured with:
• 3/8'' – 4'' diameter range
• PN16 – PN63 pressure classes
• -10°C to +220°C temperature resistance
• PTFE, graphite, or RPTFE sealing options.
