Product description:

  1. Gate valve can be divided into rising stem gate valve, which refers to the disc doing lift movement in straight line along with the valve stem, and non-rising stem gate valve which refers to the stem nut located in the disc, when the stem rotates, the disc doing lift movement in straight line.
  2. Peco lined gate valve adopts new design structure, solving the inconvenient or jammed operation phenomenon caused by particles, fibers and medium deposition in the screw groove of common non-rising gate valve.
  3. Valve installation position is not subject to any restrictions.
  4. It can sustain any corrosive medium in addition to the molten alkali metals and fluorine elements. It is ideal products used in chlor-alkali, industrial in organic chemicals, metal and mining, nitrogen and phosphatic fertilizers, petroleum refining, pharmaceutical etc.
  5. Lining material: PTFE, PFA, FEP etc.
  6. Operation methods: manual, worm gear, electric, pneumatic and hydraulic actuator.
  7. Peco lined gate valves are available as per the needs of applications in additional sizes and other than standard materials.
