3.2 Description

The GEMÜ R647 2/2-way diaphragm valve is a straight
through valve and is pneumatically operated. The valve
doesn't have a closing spring and is only closed by applying
compressed air. A diaphragm is the sealing element. The con-
trol medium applies direct pressure to the shut-off diaphragm
pressing it against the shut-off weir in the valve body. The
high-flow valve body provides compact dimensions at high
flow rates.

3.3 Function

The product is designed for use in piping. It can be closed by
a control medium or opened by operating pressure, which is
how it controls the flow.
