PROTEGO® Valve Pallet

PROTEGO® Valve pallets assure optimal functionality. For the perfect interplay between valve pallet and valve seat, different sealings options are available to suit your process conditions.

Benefit of the PROTEGO® Valve Pallet

  • Valve pallet made of stainless steel / hard-coated Aluminium; no corrosion
  • weights are secured by an adjusting ring to the valve pallet hood; constant pressure on the sealing and no-bouncing of the weights → minimum wear of parts
  • depending on the application different types of valve pallets and sealings are applicable
  • very low leakage rate due to precisely ground sealing surface
  • precision guiding prevents fl uttering and tilt of the spindle → stable operation of valve
  • multiple seal options made from high quality sealing materials
