200 NB CF8 Stainless Steel Butterfly Valve with Gear Operator Manufacturer & Exporter in India | FlowBiz Exports
Introduction
FlowBiz Exports Pvt. Ltd. supplies industrial butterfly valves for flow isolation and control across a wide range of industrial applications. The 200 NB CF8 Stainless Steel Butterfly Valve with Gear Operator is designed for larger pipeline systems that require controlled quarter-turn operation.
With a nominal size of 200 NB (DN200 / 8 inches), this valve is suitable for applications where pipeline flow must be opened, restricted or shut off. Its gear operator uses a handwheel and reduction mechanism to make manual operation easier than directly turning a large valve shaft.
CF8 is a cast stainless steel grade commonly associated with Type 304 stainless steel. The suitability of the valve depends on its complete material configuration, seat selection, pressure rating and operating conditions.
What Is a 200 NB CF8 Stainless Steel Butterfly Valve with Gear Operator?
A butterfly valve controls flow through a rotating disc positioned inside the valve body. Turning the handwheel operates the gearbox, which rotates the valve disc to open or close the flow passage.
The gear operator is especially useful for larger valves because it provides mechanical advantage and supports controlled movement. It can also help an operator position the disc without applying excessive direct force.
The 200 NB CF8 stainless steel butterfly valve is intended for industrial piping systems where the selected valve materials and pressure class are suitable for the process medium.

Key Features of the 200 NB Gear Operated Butterfly Valve
1. CF8 Stainless Steel Construction
CF8 is a cast stainless steel grade commonly used in industrial valve components. It provides useful corrosion resistance in many services, subject to fluid chemistry, temperature and operating conditions.
2. Gear Operator for Easier Operation
The gearbox provides mechanical advantage when opening or closing the valve. This is beneficial for larger valve sizes where direct operation may require greater effort.
3. 200 NB Pipeline Compatibility
The 200 NB size is commonly referred to as DN200 or approximately 8 inches. It is used in industrial pipelines where the selected valve dimensions and connections match the piping system.
4. Compact Quarter-Turn Design
Butterfly valves operate through approximately 90 degrees of disc rotation. This design can provide a compact flow-control solution compared with some other valve types.
5. Flexible Configuration Options
Depending on the product range, butterfly valves may be supplied with different body styles, seat materials, disc materials and pressure ratings. The correct combination should be selected for the intended application.
6. Controlled Disc Positioning
A gear operator allows the valve disc to be moved in a controlled manner. This can help operators achieve the required open or closed position during routine operation.
Applications of 200 NB CF8 Stainless Steel Butterfly Valves
The valve can be considered for suitable applications such as:
Water treatment plants: Flow isolation in compatible water-treatment pipelines.
Industrial process lines: Flow control in manufacturing and process systems.
Cooling-water systems: Isolation of compatible cooling-water circuits.
Chemical industries: Applications where the CF8 material and seat are compatible with the process fluid.
Utility pipelines: Flow isolation in industrial service lines.
General engineering plants: Pipeline assemblies requiring a gear-operated butterfly valve.
The suitability of CF8 stainless steel depends on the specific medium. Some chemicals, chloride-rich fluids and demanding service conditions may require a different material grade or valve construction.
Benefits of a Gear Operated Butterfly Valve
Reduced operating effort: The gearbox helps make manual operation easier on larger valves.
Controlled movement: The handwheel and gearbox allow gradual disc positioning.
Space-efficient design: Butterfly valves generally have a compact flow-control arrangement.
Versatile industrial use: Suitable configurations are available for various pipeline services.
Maintenance access: Gear-operated valves can be inspected and maintained according to the manufacturer's instructions.
How to Select the Right 200 NB Butterfly Valve
Before ordering, review these factors:
Pipeline size: Confirm DN200 / 200 NB and the required connection dimensions.
Pressure rating: Select a valve suitable for the maximum operating and test pressures.
Body and disc materials: Confirm the exact material grade of the body, disc, shaft and other wetted components.
Seat material: Select a seat compatible with the fluid and operating temperature.
End connection: Identify whether the application requires a wafer, lug or another valve configuration.
Operating conditions: Consider the medium, temperature, flow requirements and frequency of operation.
Gearbox arrangement: Ensure the operator is suitable for the valve size and required operating torque.
Inspection requirements: Identify applicable design, inspection and pressure-testing requirements for the project.
