Industrial Ball Valves — Manufacturer, Supplier & Stockist
Ball valves are quarter-turn valves that use a spherical closure element (the ball) to start, stop and regulate the flow of liquids and gases. Navjivan Valves supplies a wide range of industrial ball valves — including forged, floating, trunnion-mounted and lined variants — sourced from leading Indian manufacturers, to process plants, EPC contractors and industrial buyers across India.
Product Overview
Ball valves are prized for their simple quarter-turn operation, tight shut-off and low maintenance requirements. The valve consists of a rotating ball with a bored passage; when the bore is aligned with the pipeline the valve is fully open, and a 90° turn closes it completely. This makes ball valves a popular choice wherever fast, reliable on/off isolation is needed — from pipeline isolation and utility services to process shut-off in oil & gas, chemical and water treatment plants.
Types of Ball Valves
Forged Ball Valves
Constructed from forged carbon steel, stainless steel or alloy steel for superior mechanical strength. Suited to high-pressure and high-temperature service where cast components would be less reliable.
Floating Ball Valves
The ball is not fixed to the body; line pressure pushes it against the downstream seat to create the seal. A simple, cost-effective, widely used design for low and medium pressure applications.
Trunnion-Mounted Ball Valves
The ball is supported by trunnions (fixed shafts) top and bottom, so it does not rest on the seats. Preferred for large sizes and higher pressure classes where floating designs become impractical.
Lined Ball Valves
The body and ball are lined with PTFE or similar materials to resist highly corrosive or abrasive media, commonly used in chemical processing.
