ROUND UP
VALVES + ACTUATORS
Extending the range of diaphragm valves
Originally, this specially sealed version was developed from the
GEMÜ
601, 612 and 673 basic
types to suit particular customer requirements, and the new GEMÜ 673P9 version will now
extend the current portfolio.
The manually operated valve is available in nominal sizes DN 8 to DN
50, and has an additional seal provided by silicone O-rings
which seal the interior of the bonnet housing from the out-
side. This prevents, among other things, lubricant which
is normally used for lubricating the spindle, from leaking
when autoclaving. It also prevents moisture and dirt from
entering the bonnet interior.The GEMÜ 673P9 diaphragm valve
is autoclave-capable and sterilisable, as well as CIP/SIP capable.
As with the basic types, a standard seal adjuster and optical
position indicator are also integrated in the new version.
Thanks to their compact design, the valve bonnets are
also suitable for use on multi-port valve blocks
and tank valves.

eva.zink@gemue.deSteam jackets for
valve bodies
Mitech
designs, fabricates and
tests its steam jackets to ANSI
B16.34 - 1998.The steam jackets are
designed to keep the valve body at
a set temperature.
A hot fluid such as steam, is circu-
lated around the valve body keeping
the fluid inside both warm and in a
liquid state.
The steam circulates in the an-
nular space between the jacket and
the vessel walls and allows heat to
be transferred through the wall of
the vessel.
Mitech’s hub end Inline Globe
Control valve body is used as a base
and is modified to incorporate the
steam jacket.
Flange ends become integral,
while the flange drilling incorpo-
rates blind tapped holes.
All valves are pressure and leak
tested before and after jacketing.
There are numerous jacketing
considerations, including flange
size, full or partial coverage, types
and locations of heated medium
connections, materials, bonnet
jackets or additional heat coverage
for specific areas.
