Eccentric Plug Valve, ASTM A216, ASTM A351

Jan 01, 1970

Eccentric plug is used to cut off or connect medium in pipelines. It is utilized in petroleum, chemical industry, pharmacy, chemical fertilizer, etc. Eccentric design has low friction to ensure zero leakage. High performance resin seal can meet corrosion resistance requirements of various medium.

Advantages

1. V type seal ring can be changed on line without disassembling the operator.

2. Self-lubricated bearing provides very easy operation and low operation wearing.

3. Ductile iron plug covered wholly with rubber for drip-tight shut off assures excellent erode and corrosion resistance.

4. O-ring seals provide easy maintenance.
