Jacketed Wafer Ball Valve

NSV Jacketed Wafer Ball Valve

This jacketed wafer ball valve is designed for on/off service in applications requiring precise temperature control of the process fluid. Featuring a compact forged wafer body with integrated jacket, it allows circulation of heating or cooling media such as steam, hot oil, or chilled water. Built from high-quality forged materials, it delivers reliable sealing and structural integrity even at elevated pressures up to Class 2500.

Key Features

Body Material A105, F22, F304, F304L, F316, F316L or other available forged materials

Operation Manual lever

Pressure Rating Up to Class 2500

Size Range 1/2" to 2" (DN15–DN50)

Valve Type Full port, two-piece forged wafer, jacketed

Sealing RPTFE or graphite stem seal; soft seats in EPDM, NBR, or RPTFE

Design Standard API 607

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.
