FEATURES

  • The inner and outer surfaces are coated with electrostatic powder paint with a minimum thickness of 250 microns.

  • The valve body and flaps are designed to exhibit minimum resistance.

  • Sealing is provided by a T-section sealing ring secured circumferentially by a pressure ring at the edge of the seal.

  • Since the seal ring presses against the conically machined body seat when the valve is closed, a perfect seal is ensured in both directions.

  • Can be manufactured with an actuator upon request.

  • Since the seal ring presses against the conically machined body seat when the valve is closed, a perfect seal is ensured in both directions.

  • The seal ring can be easily replaced without having to remove the valve.

  • The seat surface is made of hard chrome or AISI 316 stainless steel weld filler, making it resistant to wear and corrosion.

  • The valve features a two-piece shaft design that increases the flow cross-section.

  • The O-ring system installed on self-lubricating bushings made of bronze and delrin ensures that valves have a longer service life without requiring maintenance.

  • It has a WRAS drinking water approval certificate.
