Pneumatic Ball Valve

NSV Pneumatic Ball Valve

This pneumatic ball valve is designed for reliable on/off control in high-flow industrial applications such as water, steam, and oil systems. Featuring a full-port design with a pneumatic actuator and manual handwheel override, it ensures fast, precise operation with fail-safe capability. Constructed from robust cast steel or stainless steel, it delivers excellent structural integrity and long-term durability.

Key Features

Body Material WCB, WCC, CF8, CF8M, CF3M, or other available cast material

Operation Pneumatic actuation with manual handwheel override

Pressure Rating Class 150 (PN16)

Size Range Up to 16" (DN400)

Valve Type Full port, floating ball, flanged end

Actuator Double-acting pneumatic cylinder with positioner option

Design Standard API 607

Operation & Advantages

The valve operates via a 4–20 mA signal that controls the pneumatic actuator to rotate the ball 90 degrees for opening or closing. The integrated manual handwheel allows for emergency operation in case of air supply failure. The full-port design minimizes pressure drop, while the floating ball structure provides tight sealing under bidirectional flow. Suitable for both automatic control and manual override in critical systems.

Typical Applications

Commonly used in power plants, water treatment facilities, chemical processing, and oil & gas pipelines where large-diameter valves are required for rapid shut-off or flow isolation.

Quality Control & Service

Manufactured per ASME B16.34 and tested in compliance with API 607. All materials are traceable and inspected for dimensional accuracy. Full documentation—including material test reports and assembly drawings—is provided. Technical support includes actuator calibration, system integration, and field commissioning.
