Benefits
-
Reliable sealing to atmosphere and absolutely tight shut-off -
The diaphragm provides absolutely tight shut-off as well as hermetic sealing to atmosphere and of all operating elements. -
Maximum service life and pressure limit -
Maximised diaphragm life and pressure limit thanks to completely enclosed, spiral-supported diaphragm. -
Excellent functional reliability -
Increased functional reliability of the diaphragm thanks to balanced diaphragm suspension. -
Excellent resistance to corrosion and abrasion -
High-quality body materials and linings offer reliability and a long service life. -
Smooth actuation | -
The thrust bearing minimises the closing torques. -
Optimised long-term operation -
The stem protection integrated in the position indicator prevents ingress of contaminants. -
Fluid purity -
Valve hydraulics without dead volume ensure optimum conditions for high-purity fluids and protection against deposits. -
Quick identification of valve position -
The valve's position can be easily identified via a clear visual indicator, also visible from a distance. -
Reliable operation -
The stem and all internal operating elements are not in contact with the fluid. |
