✅ Solid Forged Construction
Integral solid blank forging, no welding seam, high density, resistant to deformation under high pressure & thermal cycling, avoid hidden leakage risk.
✅ Trunnion Fixed Ball Design
Upper & lower trunnion integrated structure, ball only rotates without axial shift. Greatly reduces operating torque, suitable for Class 150 ~ Class 2500 high pressure and large DN size.
✅ Ultra Precision Machining & Mirror Grinding
CNC turning spherical grinding, strict sphericity, concentricity and surface roughness control (Ra ≤0.2~0.4μm), consistent sealing contact with valve seat, zero fugitive emission.
✅ Wide Material Selection
F304, F316L, CF8, CF3M, A105, Duplex, Super Duplex, Monel, Inconel, Hastelloy and other special alloys for corrosive & low-temperature service.
✅ Multiple Surface Treatment Options
Hard chrome plating, ENP electroless nickel plating, Stellite hardfacing, tungsten carbide coating, nitriding for wear & corrosion resistance.
✅ Full Customization & OEM Service
Full port / reduced bore, straight through, V-port, special groove or customized bore according to drawings. Size range from 1/2” to 56”.
✅ Standard Compliance & Testing
Manufactured per API 6D, API 607, ASME, ISO. Each valve ball undergoes dimensional inspection, surface test and pressure inspection before delivery.

FAQ
Q: What is a trunnion fixed valve ball?
A: Trunnion fixed ball body is the core sphere for trunnion mounted ball valves. Supported by upper and lower trunnions, the ball rotates in place without floating displacement, featuring low torque and stable sealing for high pressure and large bore.
Q: What is the advantage of solid valve ball vs hollow ball?
A: Solid forged valve ball has dense metallurgical structure, no welding joint, stronger rigidity, anti-deformation, better safety and longer cycle life, preferred for critical high-pressure pipeline service.
Q: Can Ballkingvalve make custom valve balls from our drawings?
A: Yes. We accept custom trunnion ball, V-port ball, special bore and groove design, provide material traceability and inspection certificate.
