Manual fluorine lined gate valve is a valve that uses fluorine plastic lining technology, which forms a protective barrier against highly corrosive media by lining the valve body cavity and key components with fluorine plastic.

The structure of the manual fluorine lined gate valve includes the valve body, the inner cavity of the valve cover, the gate plate, and the outer surface of the valve stem, all of which are lined with fluoroplastic to ensure that there is no metal exposure in the medium contact area. The flow channel adopts a full diameter design, with a gate lifting height to diameter ratio of 1:1, and a fluid resistance coefficient of<0.5, which is 40% lower than that of ordinary gate valves. The valve body, valve cover cavity, gate plate, and valve stem outer surface are all lined with fluoroplastic, covering all critical areas in contact with the medium.
parameter:
- DN： DN15~DN50
- PN： PN0.6MPa~PN4.0MPa
- Temperature range: The applicable temperature range for the medium is -50 ℃~150 ℃
- Applicable medium: Strong corrosive medium
- Lining material:Using fluoroplastics such as polytetrafluoroethylene (PTFE), FEP (F46), PCTFE (F3), etc,
- Elastic gate design:Compensate for the wedge angle deviation of the sealing surface, improve the sealing fit and effectiveness
