UNICENTS PTFE lined Butterfly Valve (or Teflon lined, PFA lined, FEP lined butterfly valve) has center disc design and resilient seat design, can be fully lined and semi lined. This products mainly applied in the condition of strong corrosion, or the condition requires high clean medium, to cut off and throttling in the pipeline.
Standard and Scope:
Size: NPS 2"～48" DN50～DN1200
Pressure Rating: Class 150 Class 150 PN6~PN25
Connection: Double flange, Wafer type, Lug type and so on
Temperature:-29℃ ~ 150℃
Application: Food stuff, pharmacy, chemical industry, petrochemical, oil, gas, water treatment, and so on.With medium: Hydrochloric acid, sulfuric acid, chlorine, phosphoric acid, strong alkaline, aqua regia etc, or portable water.
Split body, two pieces shaft, so the shaft and body are separated from the media, easy to replace the shaft without dismounting the valve from the pipe
