Flanged Ball Valves

Detailed Information on Flanged Ball Valves

Flanged ball valves are full-bore valves safely used in industrial fluid control applications requiring high pressure and temperature resistance, with body options in WCB carbon steel, stainless steel (304/316), or cast steel. The flange connection provides significant advantages in terms of ease of installation and sealing. High thermal and chemical compatibility is achieved with PTFE, RPTFE, or graphite seals.

Advantages

• • High pressure resistance (PN16–PN40, ANSI 150/300).
• • Full-bore design – minimum pressure loss.
• • WCB or stainless steel body options.
• • PTFE, RPTFE, and graphite seal options.
• • Blow-out proof safety stem design.
• • ISO 5211 actuator-compatible model options.
• • Long-lasting use in water, steam, chemical, and gas lines.
• • Industrial flange standards: DIN / EN / ANSI.

Material Specifications

• • Body: WCB carbon steel, CF8 / CF8M stainless steel
• • Ball: Stainless steel (304/316)
• • Stem: Stainless steel – blow-out proof
• • Seals/Gaskets: PTFE / RPTFE / Graphite
• • Flange Standards: DIN 2501, EN 1092-1, ANSI B16.5
• • Connection: PN16–PN40, ANSI 150/300

Application Areas

• • Chemical and petrochemical plants
• • Water and wastewater treatment systems
• • Steam and high-temperature lines
• • Natural gas and industrial gas circuits
• • Oil, diesel, and fuel lines
• • HVAC systems and power plants
• • Pump stations – tank outlets
• • Process control lines

Technical Specifications

Flanged ball valves are generally manufactured with:
• DN15 – DN300 diameter range
• PN16 – PN40 pressure classes
• -20°C to +260°C temperature resistance
• PTFE / RPTFE / Graphite sealing options.
