    Product Description

    1. Fluoroplastic Lined Single Seat Control Valve has valve body and plug fully lined with fluoroplastic, isolating metal base from strongly corrosive media.

    2. Lining materials selectable from PFA, FEP, PTFE and other fluoroplastics, resistant to strong acid, strong alkali, strong oxidants and other strongly corrosive media.

    3. Metal body base material and fluoroplastic lining grade can be selected according to corrosive medium temperature and concentration.

    4. Used in chemical, pharmaceutical and pickling process pipelines for medium flow and pressure regulation.

    Features & Benefits

    1. All wetted parts fluoroplastic lined, isolating all strong acid and alkali corrosive media, excellent corrosion resistance.

    2. Lining formed with metal base under high temperature and pressure, strong adhesion, not easy to delaminate or peel.

    3. Fluoroplastic resilient sealing pair with reliable sealing performance in closed state.

    4. Medium in flow channel only contacts fluoroplastic, not metal body.

    5. Stable regulation, easy maintenance.

    6. Flanged connection, easy installation removal and maintenance, suitable for strongly corrosive chemical working conditions.

    7. 45°Y type straight flow channel, smooth and straight flow, low flow resistance, medium not easy to accumulate.
