Product Description
It's special for controlling the noncorrosive or the strong corrosive media.Its body inner surface is unlined or lined with different fluorine plastic which can be selected to suit with different working temperatures and fluid pipelines.
Suitable temperature: ≤85ºC,≤100ºC,≤120ºC,≤150ºC(According to the materials of lining and diaphragm)
PTFE Lined Pneumatic Weir Type Diaphragm Valve Features:
The diaphragm valve is an especial break valve:
1.The elastic sealed open and close element can avoid the inner leak.
2.The clipper-built interval channel can keep the small loss of pressure.
3.It hasn't the stuffing box,so it doesn't leak.
4.The body and bonnet are separated by the middle diaphragm which can't be corroded by the medium.
