Stop Valve Isolating Valve NBR NR EPDM FKM CR Pneumatic Cut Off Valve Rubber Diaphragm


Cut Off Valve Rubber Diaphragm​ Introduction:


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.


In the design of some medium and low pressure regulators, in order to solve the problem of unbalanced pressure regulator disc and improve the performance of the regulator, the method of installing a balanced diaphragm is often used. Installing a balancing diaphragm increases the differential pressure between the inlet and outlet pressures of the regulator. In the voltage regulator industry, it is called a balanced diaphragm in terms of use, and it is called a rolling diaphragm in rubber, instrumentation, machinery and other industries.


Cut Off Valve Rubber Diaphragm​ Material 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.
