Floating Flanged Ball Valves

Floating designs are commonly selected for general shut-off service in smaller to medium pipeline sizes and moderate pressure conditions. The ball can move slightly toward the downstream seat under pressure. This helps achieve sealing performance in many industrial on/off applications.

These valves are often used in chemical processing, water systems, gas lines, oil lines, and general utility pipelines. Buyers should confirm pressure class, temperature, media characteristics, seat material, bore type, and operation needs.


Trunnion Mounted Flanged Ball Valves

Trunnion mounted designs are often preferred for larger sizes, higher pressure service, and demanding pipeline applications. The ball is supported by trunnions, which reduces seat load and improves operation stability under higher differential pressure.

SDF’s broader experience in high-temperature and high-pressure industrial valves supports engineered selection for power plants, oil and gas pipelines, petrochemical systems, and other mission-critical applications.


Fire-Safe and API Flanged Ball Valves

Fire-safe designs are relevant for oil, gas, petrochemical, natural gas, and other critical process systems. SDF has API 607 fire-safe certification capability and API 6D certification capability for pipeline valve applications. These capabilities are subject to the specific model and project requirements.

For API-related inquiries, buyers should specify the required standard, pressure class, flange standard, testing documents, material requirements, and project-specific inspection procedures.

Class 300 Flanged Ball Valve Higher pressure industrial and process systems Confirm body material, seat material, and actuator torque
Higher Pressure Classes Demanding oil, gas, petrochemical, or power-related service Engineering review recommended for sealing, structure, and testing
Flanged End Standard Project-specific pipeline flange requirements Confirm standard, face type, bolt pattern, gasket requirement, and installation drawings


Carbon Steel Flanged Ball Valves

Carbon steel models are often selected for oil, gas, steam-related utility lines, district heating, and general industrial pipelines. They are suitable for many process and utility services when the media matches the selected body, trim, and seat materials.


Stainless Steel Flanged Ball Valves

Stainless steel models are commonly used in chemical processing, petrochemical media, acid service, pharmaceutical processes, and corrosion-sensitive applications. Buyers should confirm media composition, corrosion level, temperature, and any cleanliness or process documentation requirements.


High Pressure Flanged Ball Valves

High pressure designs require careful review, especially for larger sizes, high operating pressure, high temperature, or hazardous media. SDF’s specialization in high-temperature and high-pressure valve applications supports power plants and mission-critical systems that need more than catalog selection.
