Schubert&Salzer 7069

Diaphragm valve for ultraagressive media

Pneumatically operated control valve made of plastic for controlling ultrapure and aggressive fluids.

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.
