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.

Steam 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.
