Stainless Steel Penstocks Sewage

Description

The Stainless Steel penstock(Sluice gates) construction allows a very large design flexibility, the result being a lighter weight and easier-to-install gate. The frame can be either open (no yoke) or self-contained configurations, providing a solid one piece gate. In the case of an open frame with operator, an operating floor located over the channel to support the pedestal is necessary. Stainless Steel penstocks have very good corrosion and erosion resistance and can be operated many years with a minimum maintenance.

Depending on the direction of water pressure acting on the gate, the penstocks are classified as below.

  • On-Seating Penstock: On-seating head refers to the water pressure forcing the penstock into the wall/ Frame.
  • Off-Seating Penstock: Off-seating head refers to the water pressure forcing the stoplogs out of the wall/ Frame.
  • On-Off Seating Penstock : Penstock designed to withstand water pressure both against the wall/Frame and away from wall/Frame.
