Fabric Reinforced Rolling Diaphragm Tear Resistance Valve Rubber
Diaphragm
Product overviews:
The rolling diaphragm is shaped like a top hat in the free state.
It is made of rubber with silk cloth. The middle hole on the top is
used for installing the valve stem. In order to fit, fix and seal,
the top and bottom can be equipped with 0 type edge changer, or the
bottom surrounding with mounting hole.
Advantages:
• Fabrication technics of textile makes the product tear resistance
stronger
• High quality raw materials ensure the excellent performance of
the material itself
Materials details:
For the present, common materials for rolling diaphragm are:
natural rubber (NR), nitrile butadiene rubber (NBR), the
performance of the two materials can meet the needs of most
industrial environments. In special industrial environments (high
temperature resistance, acid and alkali resistance) could use EPDM,
fluorine rubber (FKM), neoprene rubber (CR) for production, but the
cost is relatively high.
