Descriptions
Using two pieces valve body structure, only the fluorine plastic lined disc and seat contact the liquid. It can used for all kinds of corrosive mediums excep “melting alkali metal” and Fluorine. It is widely used in chemical industry, soda factory, beverage and other industries.
Virgin PTFE Liner
In order to assure long-life span and superior quality, all PTFE parts (seats as well as encapsulated discs) are moulded from pure, virgin PTFE material. Virgin PTFE provides for an excellent chemical resistance and can be used with aggressive media. Typical characteristics of fluoropolymer resins include chemical inertness, exceptional dielectric properties, toughness and flexibility, low coefficient of friction, negligible water absorption and non-stick characteristics. All these properties provide increased protection against permeation of the line media. Further, low coefficient of friction reduces valve operation torque.
