Alis Valves Manual 2 Pc Flanged Ball Valve Manufacturer in India is designed for reliable on/off flow control in industrial piping systems. Its two-piece body construction provides a robust design, while the flanged ends allow secure bolted connections to compatible pipelines. Operated by a manual lever, it is suitable for water, oil, gas and other compatible process fluids across a range of industrial applications.
Product Specifications and Overview
The Manual 2 Pc Flanged Ball Valve is used to start or stop fluid flow in industrial pipelines. It features a two-piece body construction and flanged end connections, making it suitable for process systems that require dependable shut-off and convenient pipeline installation.
The valve operates through a manual lever that rotates the internal ball by 90 degrees. When the ball bore aligns with the pipeline, fluid can pass through; when the ball rotates to the closed position, the bore blocks the flow passage.
Its two-piece construction provides a practical and sturdy design for industrial service. The flanged connections use bolts and a suitable gasket to form a secure joint with the mating pipeline flanges. The valve is available in different material and pressure-rating configurations, depending on the manufacturer’s design.
Manual 2 Pc Flanged Ball Valves are commonly used in water treatment, oil and gas handling, chemical processing, power plants and general manufacturing. The correct valve should be selected according to the fluid, operating pressure, temperature, required leakage performance and applicable piping standards.

Frequently Ask Questions
It is a manually operated ball valve with a two-piece body and flanged end connections, used to control or isolate fluid flow in pipelines.
A 2-piece valve has a body assembled from two main sections. A 3-piece valve has a separate centre section and two end sections, which can make certain maintenance operations more convenient.
A full-bore valve has a ball passage close to the pipeline's internal diameter. A reduced-bore valve has a smaller passage that may create greater flow restriction.
Possible causes include damaged seats, worn seals, incorrect gasket installation, loose flange bolting, damaged flange faces or operation outside the rated conditions.
It means the valve body is assembled from two main pieces. The construction and maintenance procedure depend on the manufacturer's design.
PTFE and RPTFE are common options in suitable designs. Other seat materials may be available depending on the application.
The seat forms the sealing interface around the ball to help prevent flow through the valve when it is closed.
