Permanent Neodymium Block Magnet (UNI-BLOCK-003)
Ball Valve is named by the ball inside to control the valve open and close by rotarying it 90 degree. It can be used either as shut-off valve or control valve. plastic ball valve include integral type ball valve, true union ball valve and compact ball valve. end connection by flange, socket welding and thread screw, opetate by hand lever, gear box, Electric Actuator and pneumatic actuator.

Neodymium permanent magnets (ND-Fe-B) are composed of neodymium, iron, boron and a few transition metals. These magnets are extremely strong for their small size, metallic in appearance and found in simple shapes such as rings, blocks and discs.
1. Attributes of Neodymium
2. Very high resistance to demagnetization
3. High energy for size
4. Good in ambient temperature
5. Moderately priced
6. Material is corrosive and should be coated for long term maximum energy output
7. Low working temperature for heat applications, but higher levels of heat resistance materials are being introduced periodically.
Plastic ball valves have the advantages as follows: 1, good corrosion resistance. 2, small size, light weight. 3, good sealing performance. 4, quick open and close, easy operate and maintaince. plastic ball valve is mainly used in water treatment, agriculture irrigation, swiming pool water supply, fish farm, mining, steel factory, chemical industrial, etc.
