Advantages and purpose
It′s special for controlling the no corrosive or the usual corrosive media, lts body inner surface is unlined or lined with different rubbers which can be selected to suit with different working temperatures and fluid pipelines.
The diaphragm valve is an especial break valve:
- The elastic sealed open and close element can avoid the inner leak.
- The clipper-built interval channel can keep the small loss of pressure.
- It hasn′t the stuffing box, so it doesn′t leak.
- The body and bonnet are separated by the middle diaphragm in order that the bonnet and stem over the diaphragm aren′t corroded by the medium.
- The diaphragm is changeable and the expense of maintenance is low.
- The various lining materials can be suitable for kinds of media and have the good corrosion-resistance
