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.

  • Low flow resistance coefficient

  • Streamlined straight-through type body design

  • 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.
