Diaphragm valve - Import export

In contrast to other valve designs, only two diaphragm valve components come into contact with the operating media the diaphragm itself and the valve housing. The long service life, reliability, safety and resistance against aggressive and abrasive media, combined with the excellent control quality of the directly mounted digital positioner result in an ideal control valve with minimal maintenance effort and low operating costs. With its pneumatic actuator and proven Schubert & Salzer positioner, the diaphragm valve 7069 equipped with plastic housing is not only a true control valve alternative for applications in the fields of chemistry, cosmetics, environmental engineering and water treatment, it is also ideal for galvanising technology as well as for the food and beverage industry. A true all rounder.

The GEMÜ 650TL diaphragm valve is a manual tapping valve with automatic closing function which is pneumatically operated.

The 5P diaphragm valve can be used in practical applications as a shut-off fitting, a safety valve and also in the 2/3-way version for distributing or collecting. The key to a long service life and reliability is in the structural design of the diaphragm valve. In comparison to comparison diaphragm valves, the flow is controlled not by the diaphragm alone, but in combination with a 90° sealing cone. The advantage of this is that it saves wear on the diaphragm and prevents particles from accumulating.

SISTO-C 2-piece TFM/EPDM diaphragms Diaphragms with thicker TFM film are also available for SISTO-C valves. In order that the actuation force can be fully utilised without affecting the plastic diaphragm’s long service life, the TFM diaphragm is backed up by a second diaphragm made of EPDM. A metal pin embedded in the TFM diaphragm helps lifting the diaphragm and thus opens the valve. To avoid damage to the diaphragm during valve closure, the metal pin is fitted to the bonnet assembly by means of a floating nut. Both TFM and EPDM comply with FDA specifications. This 2-piece TFM/EPDM diaphragm is perfectly suited to applica-tions involving high chemical and thermal stress.

SISTO-C Elastomer diaphragms bonded with TFM Manufactured in a specially developed process, these compo-site diaphragms are made of an FDA compatible EPDM rubber which is firmly bonded to a TFM film featuring improved mechanical properties and lower permeability compared with conventional PTFE. This material quality also complies with FDA specifications and the EU1935. The TFM’s excellent chemical and thermal properties make this diaphragm type the first choice for applications with chemically aggressive media and high temperatures. This diaphragm type is also recommended for use in media which need to be protected against rubber abrasion and fluids containing oils and greases. As the rubber is fully covered by the TFM sheet, even mechanical damage to the sheet does not result in cavity formation and therefore to undefined spaces which cannot be cleaned. This composite diaphragm is vacuum-resistant.

SISTO-C Elastomer diaphragms SISTO soft elastomers are made from an EPDM rubber which has been designed to withstand an operating temperature of up to 140°C. The diaphragm material corresponds to FDA requirements, EU1935 and has been tested and certified in accordance with USP guidelines. The diaphragms are well suited for use in “cold applications” such as in WFI systems, and thanks to their high ozone resistance they have proven extremely successful in CIP applications with all types of standard cleaning media. These EPDM diaphragms are also ideal for sterile steam applications. A piece of fabric integrated into the EPDM rubber enables the diaphragm to be used under vacuum. The diaphragms can easily handle solids-loaden fluids and have a long service life.
