Ball Valves

Ball valves are essential for reliable on/off fluid control in pipelines handling liquids, gases, and corrosive media. Known for their quarter-turn operation, tight sealing performance, and long service life, they are widely used in oil and gas, petrochemical, power generation, water treatment, and general industrial systems.

Through CNMFRS.com, buyers can access a wide range of valve configurations, including floating, trunnion-mounted, full bore, reduced bore, and multi-port designs, available in materials such as stainless steel, carbon steel, and specialty alloys.

As a leading ball valve online marketplace in China, CNMFRS.com connects global buyers with trusted Chinese manufacturers and suppliers of high-quality ball valves for diverse industrial applications.

Explore our comprehensive range of ball valves, offered in multiple types, standards, materials, sizes, pressure ratings, actuator configurations, seat materials, and stem sealing options for diverse industrial applications.

Ball valves are quarter-turn valves that utilize a hollow, pivoting spherical ball to control the flow of liquids, gases, or corrosive media. When the ball's bore aligns with the pipeline, fluid flows freely; a 90° rotation blocks the passage, providing fast, reliable, and leak-proof shutoff. Known for their durability, tight sealing, and quick operation, ball valves are essential components across energy, chemical, water management, and general manufacturing sectors.

Key Product Categories of Ball Valve

1. By Design Configuration

• Floating Ball Valves: The ball is free-floating, pushed against the downstream seat by line pressure. Ideal for low- to medium-pressure applications.
• Trunnion-Mounted Ball Valves: Ball supported by trunnions; suitable for large diameters and high-pressure systems.
• Full Bore / Full Port: Bore matches pipeline size; minimal pressure drop, suitable for pigging operations.
• Reduced Bore / Standard Port: Smaller bore; economical and sufficient when full flow is unnecessary.
• V-Port Ball Valves: V-shaped ball opening for flow control or throttling applications.
• Multi-Port Ball Valves: 3-way or 4-way designs for mixing, diverting, or complex piping layouts.
• Top-Entry Valves: Maintenance-friendly design with removable bonnet.
• Side-Entry / Split-Body Valves: Three-piece construction for easy servicing.
• Fully Welded Valves: Permanent pipeline installation with maximum integrity.

2. By Material Construction

• Body Materials: Stainless steel (304/316/316L, CF8/CF8M), carbon steel (WCB/A105), brass, bronze, alloy steel, Inconel, Hastelloy, duplex/super duplex, PVC, CPVC.
• Ball Materials: Stainless steel, chrome-plated steel, Monel, ceramic-coated, PFA-lined, or alloyed metals for abrasion resistance.
• Seat Materials: PTFE, RPTFE, PEEK, Nylon, Delrin, reinforced plastics, or metal-to-metal (e.g., Stellite) for extreme pressures and temperatures.
• Seal Materials: Viton, EPDM, Buna-N, Kalrez for chemical compatibility.
