Operation & Advantages
The valve operates with a 90-degree turn to open or close the flow path. The fully enclosed jacket enables uniform heat transfer around the ball cavity, preventing solidification, crystallization, or viscosity increase in sensitive media. The forged two-piece design ensures high strength, minimal leakage risk, and easy in-line maintenance. Suitable for high-pressure services up to Class 2500 while maintaining compact dimensions.
Typical Applications
Ideal for chemical processing, pharmaceutical synthesis, food and beverage production, and specialty gas systems where temperature-sensitive or high-purity fluids must be handled under pressure. Commonly used with molten sulfur, heavy oils, resins, and cryogenic pre-heating lines.
Quality Control & Service
Valves are manufactured in accordance with ASME B16.34 and API 607 requirements. Each unit is inspected for dimensional accuracy, material traceability, and assembly integrity. Full documentation—including material test reports and calibration certificates—is provided. Technical support includes sizing, installation guidance, and commissioning assistance.
