VC2000 Series Sliding-Stem Fluorine-Lined Single-Port Valve, economic and high-effective one, can be almost used in all corrosive chemicals which are within allowable range of temperature and pressure, which realizes the protection of human, environment and production.
◆Valve body inner wall and trim contacted with fluids both are lined with a thickness of 3mm F46 or F4
antiseptic material to ensure that there is no contact between medium and metal.
◆Bellows and packing used as double seal, and the top of valve plug is hermetically connected with the
upper end of PTFE bellows, and the lower end of the bellows is hermetically connected with valve body,
bonnet and seat by use of bolts and nuts. The bellows insulates medium from the outside with good
tightness. Once the bellows is broken, the packing can act as the secondary protective seal. And a
disastrous consequence can be avoided in case the bellows burst and lose efficacy.
