  • Because of its stainless steel construction, the series 20 has high corrosion and erosion resistance and can be operated for many years with minimum maintenance. Fabricated stainless steel provides virtually limitless design flexibility. The result is a lighter weight and easier-to-install gate.

    • The stainless steel frame on the series 20 is a flange back type available in open or self-contained configurations, providing a solid one-piece gate.

    • The rigidity provided by the flange back frame makes it easier to handle in transportation and installation with less risk of distortion.

    • The seal bolting is completely separated from the flange anchoring, allowing the flange to be modified to better suit all particular applications. This feature also allows the gate to be completely factory assembled as well as tested for operation and leakage before being shipped. It also eliminates any on-site assembly and adjustments.
