Rolling 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.

Rolling Diaphragm Introduction:
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.
The rolling diaphragm is in the shape of a top hat in the free
state. It is made of rubber with silk cloth. The top middle hole is
used to install the valve stem. In order to install, fix and seal,
the top and bottom can have O-ring edges. Or in the form of fixing
holes around the bottom edge.
Rolling Diaphragm Characteristics:
• Fabrication technics of textile makes the product tear resistance
stronger
• High quality raw materials ensure the excellent performance of
the material itself
