果冻久久尤物

1, the selection is through the elegant. Meet the relevant standards at home and abroad, the overall quality of the material high;

     2, The sealing surface of the gate and the valve seat is made of hard alloy with different hardness. It has the characteristics of reliable sealing, abrasion resistance, abrasion resistance, long life, high temperature resistance, high hardness and corrosion resistance.

     3, the use of wedge-shaped flexible gate structure, large diameter set thrust bearings, friction is small, and with the impact of hand wheel, open and close easily;

     4, can use a variety of standard pipe flange and flange sealing surface forms to meet the needs of various projects and user requirements.

Flange valve in addition to the above advantages, there are good corrosion resistance, abrasion resistance and abrasion resistance, widely used in petrochemical, thermal power plants.
