YDTech™ OEM of loose hollow valve spheres cores, ceramics(silicon nitride, zirconium oxide)! supplier of half balls bodies for ball valves(stainless,chrome, titanium) in china.

through many years in the industry,our valve ball has developed unique technologies for creating balls which have applied to creating unusually shaped products and for prototype products under development. any typles of hollow valve balls we can manufactured, such as "V" shaped or "V" variants hollow valve balls, 3 -4 three way hollow valve bodies

we offers valve balls and seats, and provides spherical grinding services for many industries including military, mining, pulp and paper, petroleum and chemical. we produce precision valve balls for use in severe duty, high pressure, and high tolerance applications.

a ball valve is a type of valve using a ball as its primary component. the quality of the ball greatly affects the performance of the valve, particularly the control of the fluid that passes through. the reputation of a manufacturer therefore depends on the sphericity of the ball.

chrome alloy steel balls - primarily used in bearings but also found in other industrial equipment application. chrome steel balls are used in a wide array of applications from aerospace to automotive. the applications of chrome steel balls most people are familiar with are ball bearings, both radial and linear.

producing all sizes of balls from miniature to large-diameter in small quantities or mass production, our valve ball delivers high quality with a short lead time and is confident in their unique production capacity and the equipment they have created specifically for better products.
