Low noise control butterfly valve
Membranventil
ERHARD Membran-Absperrventile sind hervorragend geeignet zum Absperren, Steuern und Überwachen und sind somit individuell einsetzbare Industriearmaturen.
Die ERHARD Membran-Absperrventile zeichnen sich durch tropfdichten Verschluss auch bei verunreinigten Medien aus. Die Haube und das Druckstück kommen nicht mit dem Medium in Kontakt. Außerdem verfügen die Membranventile über serienmäßige Hubbegrenzung.
Die ERHARD Membran-Absperrventile sind mit zahlreichen Antriebsarten für manuellen und automatischen Betrieb lieferbar. Sie sind universell einsetzbar durch individuell auf das Medium angepasste Kombinationen von Werkstoffen für Gehäuse und Membran.
Metal seated butterfly valve
Metal seated butterfly valve
“The Somas metal seated butterfly / shut-off and control valve type VSS is suitable for controlling and shutting off liquids, steam and gases over a wide temperature range.
The triple eccentric design allows the use of a solid stainless steel seat due to the special contour of the disc. The disc geometry and the shape of the seat provide excellent tightness.
The seat is resistant to high flow velocities and ensures good tightness, even under difficult operating conditions. The seat, which is available in different materials, can be replaced.
The VSS valve was developed as a wafer valve and can also be supplied as a lug type valve (with threaded bores).”
Metal seated butterfly valve for exhaust gas applications
“Somas has developed a range of metal seated butterfly / shut-off and control valves for exhaust gas applications that meet the requirements of EN 12516-2 and ASME B16.34.
Typical applications for these valves in diesel engines, gas engines and exhaust gas systems are:
waste gates, EGR, turbo shutdown, slow steaming, air bypass, gas scrubbers, heat recovery
Somas exhaust gas valves have many technical advantages.
The geometry of the disc is designed in such a way that it only comes into contact with the seal when it is fully closed. This ensures that the wear on the sealing surface is kept to a minimum and a long service life is guaranteed.
The valves have a solid seat design and are therefore resistant to clogging.
The shaft bearings are designed as standard in metal-to-metal pairs, which means that the valves can be used without any problems in high temperature applications.
All valves are supplied as standard with a graphite gland. Other materials are available.
Somas VSS / HT and MTV / HT valves are bi-directional and can therefore be installed in both directions.”
Metal seated butterfly valve for marine applications
“The metal seated butterfly / shut-off and control valves type MTVC and MTVCL are intended for marine applications.
The butterfly valve type MTVC is a wafer type valve for mounting between flanges.
The valve MTVCL is a lug type valve.
