Frequently asked questions
As standard, these vacuum breakers are delivered freely adjustable. However, we can also preset them for an extra charge and seal them accordingly.
No, this is not possible. The vacuum breakers must be operated in a vertical installation position (connection below).
The membrane-operated pressure reducing valve is frequently used in applications with low to normal back pressure. Due to the membrane, it also delivers more sensitive regulation.
The piston-operated pressure reducing valve is frequently used with high back pressures and aggressive media. It has an extremely robust design, giving it a high level of safety in case of pressure surges.
Basically, our types are suitable as a vacuum version for a rough vacuum. However, this still depends on the location and the intended use of the valve. Because our sight glass valve is only as vacuum-resistant as the customer's entire system. In addition, it still depends on the height present in the place of use in relation to sea level. We can therefore only confirm rough vacuum in our vacuum versions, with the indication that it depends on the environment variable. All further stages that come below are always possible in theory. In practice, we can only confirm this after a previous vacuum test and, if necessary, by a suitable modification of the valve
