The elastic modulus of the low elastic plastic material used for plastic ball production reduces the need for more precision, so the tolerance of the diameter of the metal ball is larger than that of the metal ball.

In the use of plastic ball valve, it is essential that the valve seat has a smooth finish, no edges and burr. Recommended seat is the angle of the 80 corners.

Chemical resistance:

The choice of plastic ball is more complex than the metal ball, because the chemical properties of the plastic material is more complex than the metal material.

From our two most resistant to chemical corrosion of material is Teflon and fluorine rubber plastic ball (fluorine rubber & reg; materials). Fluorine rubber plastic ball is one of the most hot, fluid resistant synthetic rubber development, and at the same time by the chemical substances of such a small Teflon plastic ball, it is described as an exception more practical. However, it is important to distinguish between strict chemical reactions and physical reactions, such as absorption, which may be related to each other, which may affect a particular application.

For a particular application, the suitability of a plastic ball is best judged from the mechanical stress of the test ball, thermal effects and chemical attacks that are likely to occur under operating conditions.

Plastic ball technical advice is provided free of charge, but because we do not control the actual operating conditions, we can not guarantee that our plastic ball program must be OK, plastic ball of any particular application and the final choice of the material is in the customer's own decisions, the company's comments on plastic balls can only give you a reference.
