1. Product Overview
A valve ball is the core sealing and flow control component of industrial ball valves, used to open, close and regulate pipeline fluid flow. Our precision-machined valve balls feature zero leakage, excellent wear resistance and stable performance under high-pressure, high-temperature and corrosive conditions. Available in full port, reduced port, V-port and custom designs, they serve oil & gas, chemical, water treatment, energy and other industrial piping systems.
We provide stainless steel, carbon steel and ceramic valve balls with complete specifications, offering reliable OEM & ODM customization for global ball valve manufacturers.
2. Core Working Principle
Featuring a central flow bore, the valve ball rotates 90° via valve stem and actuator. It fully opens for low-resistance fluid flow when aligned with the pipeline, and tightly seals the pipeline to achieve bubble-tight shut-off when rotated vertically. Our precision valve balls deliver stable flow control, flexible switching and consistent sealing during long-term cyclic operation.
3. Product Key Features & Technical Advantages
-
Ultra-High Precision Machining: Adopts CNC integral forming and fine grinding, with spherical roundness controlled within ±0.005mm and ultra-smooth surface, eliminating friction gaps to realize zero-leakage sealing.
-
Superior Material Durability: Made of premium SS304, SS316, SS316L, 2205 duplex steel, WCB carbon steel and industrial ceramic, featuring high hardness, oxidation resistance and anti-corrosion performance for diverse fluid media.
-
Low Flow Resistance Design: Full-port balls ensure straight-through flow with negligible pressure loss; V-port balls support accurate linear flow regulation for throttling and proportional control scenarios.
-
High Pressure & Temperature Resistance: Integral forging structure ensures structural stability, supporting working pressure up to 10000PSI and temperature ranging from -40℃ to 450℃, adaptable to extreme industrial conditions.
-
Long Service Life & Low Maintenance: Premium polishing and surface coating reduce seat friction and abrasion. Validated by thousands of switch cycles, the balls operate stably long-term with low maintenance costs.
-
Full Compatibility & Customization: Compliant with ANSI, DIN, GB, JIS standard dimensions. Custom bore size, ball diameter, special coating and non-standard structures are available for personalized valve matching.
4. Main Product Types
-
Full Port Valve Ball: Matches pipe inner diameter for minimum pressure drop, ideal for high-flow pipeline systems.
-
Reduced Port Valve Ball: Compact, lightweight and cost-effective, widely used for conventional water and gas piping systems.
-
V-Port Valve Ball: Features a V-shaped notch for linear flow adjustment, perfect for precise fluid throttling and control applications.
-
Ceramic Valve Ball: Boasts ultra-high hardness and superior corrosion resistance, suitable for strong acid, alkali and high-wear working environments.
