Product Description
The G41J rubber lined manual diaphragm valve is a special shaped valve with a cut-off function. Its opening and closing parts are composed of a diaphragm made of steel discs and soft materials (rubber and fluoroplastic composite), and the valve body cavity is separated from the valve cover cavity to achieve the purpose of cutting off the medium inside the pipe.
FEP/PTFE/F4/PFA Lined Pneumatic Normally Closed Weir Type Diaphragm Valve Features:
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.
5.The diaphragm is changeable and the expense of maintenance is low.
6. The various lining materials can be suitable for all kinds of media and have the good corrosion-resistance.
FEP/PTFE/F4/PFA Lined Pneumatic Normally Closed Weir Type Diaphragm Valve Purpose:
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
