PTFE Lined Diaphragm Valve Features:

1.GOOLE PTFE lined diaphragm valve is ideally suitable for shut-off, flow control and throttling of corrosive process media in either liquid or gaseous state. 
Its main features are heavy-duty, robust construction, maintenance-free, easy replacement of components on site. Convenient, flexible and accurate open or close.

2. PTFE Lined Diaphragm Valve can sustain any corrosive medium in addition to the cast metals and fluorine elements. It is ideal products used in industrial in organic chemicals, metal and mining, nitrogen and phosphatic fertilizers, petroleum refining, pharmaceutical etc.

3.PTFE Lined Diaphragm Valve can not be used for medium with hard particles, which will cause diaphragm damage and leakage.

4.The working temperature cannot exceed the specified range (FEP below 120 Deg C,  PFA Below 180 Deg C).

5. Users should avoid open or close the diaphragm valve frequently as it will affect the sealing performance.

6.Lining material: PFA, FEP, PO etc.

7.Operation methods: manual, worm gear, electric, pneumatic and hydraulic actuator.

8. Goole lined diaphragm valves are available as per the needs of applications in additional sizes and other than standard materials, e.g.: PFA/PTFE/FEP/PO Lined Ball Valve, Butterfly Valve, etc.
