Diaphragm Valve,

Metal

Construction
The GEMÜ 601, 612 and 673 manually operated diaphragm valves have a
temperature resistant plastic handwheel, GEMÜ 602 has a stainless steel GEMÜ 601
handwheel. Bonnet and internals are made all of stainless steel.
An integral optical position indicator and a seal adjuster to increase service
life of the diaphragm are included as standard.

Features
• Suitable for inert and corrosive* liquid and gaseous media
• Chemical resistance of bonnet
• CIP/SIP cleaning and sterilizing capabilities
• Autoclave capability
GEMÜ 602
• Insensitive to particulate media
• Valve body and diaphragm available in various materials and designs
• Compact design (ideal when space is at a premium)
• Stepless minimum flow regulation due to seal adjuster

Advantages
• Hermetic separation between medium and actuator
• Optional flow direction
• Installation for an optimized draining is possible
• Long service life of the diaphragm due to patented seal adjuster
(US-Pat. 5 377 956)
• Valve body also available in multi-port designs (M-block and T-body) or
as tank bottom valve body

Working medium
Corrosive, inert, gaseous and liquid media which have no negative impact on the physical and chemical properties of the body
and diaphragm material.

¹ The sterilisation temperature is valid for steam (saturated steam) or superheated water.
² If the sterilisation temperatures listed above are applied to the EPDM diaphragms for longer periods of time,
the service life of the diaphragms will be reduced. In these cases, maintenance cycles must be adapted accordingly. Steam input
This also applies to PTFE diaphragms exposed to high temperature fluctuations.
PTFE diaphragms can also be used as moisture barriers; however, this will reduce their service life.
The maintenance cycles must be adapted accordingly. Process pipe
GEMÜ 555 and 505 globe valves are particularly suitable for use in the area of steam generation and distribution.
The following valve arrangement for interfaces between steam pipes and process pipes has proven itself over time: Steam distribution    Sterile process
A globe valve for shutting off steam pipes and a diaphragm valve as an interface to the process pipes.

All pressures are gauge pressures. Operating pressure values were determined with static operating pressure applied on one side of a closed
valve. Sealing at the valve seat and atmospheric sealing is ensured for the given values. Information on operating pressures applied on both
sides and for high purity media on request.

Kv values determined acc. to DIN EN 60534, inlet pressure 5 bar, ∆p 1 bar, stainless steel valve body (forged body) and soft elastomer diaphragm.
The Kv values for other product configurations (e.g. other diaphragm or body materials) may differ. In general, all diaphragms are subject to
the influences of pressure, temperature, the process and their tightening torques. Therefore the Kv values may exceed the tolerance limits of
the standard.
The Kv value curve (Kv value dependent on valve stroke) can vary depending on the diaphragm material and duration of use.
