Weir-type diaphragm valve to DIN/EN with flanged ends or threaded socket ends, in straight-way pattern; shut-off and sealing to atmosphere by supported and confined diaphragm; body with coating or lining, position indicator with integrated stem protection. All moving parts are separated from the fluid by the diaphragm. Maintenance-free.
Benefits
- Maximum service life and pressure limit
- The diaphragm is confined and supported for maximum diaphragm life and pressure limit.
- Reliable sealing to atmosphere and absolutely tight shut-off
- The specially confined diaphragm provides absolutely tight shut-off as well as hermetic sealing to atmosphere and of all operating elements.
- High corrosion resistance
- High-quality linings offer reliability and a long service life.
- High functional reliability
- Balanced suspension of the diaphragm increases the diaphragm’s functional reliability.
- Fluid purity
- The valve’s design without dead volumes ensures optimum conditions for high-purity fluids and prevents deposits.
- Optimised long-term operation
- The stem protection feature integrated in the position indicator prevents ingress of contaminants.
- Smooth actuation
- The thrust bearing minimises closing torques.
- Readily identifiable position
- The valve’s position can be easily identified via a clear visual indicator, also from a distance.
- High operating reliability
- The stem and all internal operating elements are not in contact with the fluid.
