Features
- The double eccentric structure ensures low operating torques and
zero leakage performance.
- The valve features inner and outer surfaces coated with an average
250-micron thickness of fusion-bonded epoxy (FBE), with a minimum of 300microns available upon request.
- Higher thicknesses are available upon request.
- Low moments are achieved by reducing friction through self-lubricating bushings.

- The ductile iron body and disc enable the valve to withstand high
stretching stresses on the pipeline.
- The valve boasts high impact resistance.
- Pressure loss is minimized through a disc designed in accordance
with the direction of flow.
- Double shaft design results in minimal pressure loss.
- Sealing gaskets made of EPDM (default), NBR, or VITON can be disassembled and replaced easily in the field,
according to operating conditions anddemand.
- The o-rings on the bearing bushings protect the disc pin holes
against corrosion (Dry shaft).
- A retaining ring is assembled to the disc with imbus bolts, further protecting the disc against corrosion by placing o-rings under the bolts.
- A gearbox assembled on the top flange allows for easy valve opening and closing with very low torques.
- Lifting lugs and feet facilitate weight balance during transport and installation.
- Stainless steel welding enhances the valve’s sealing resistance.
