The construction of Stainless Steel penstock allows very large design flexibility which results in a lighter weight and easier to install a gate, the frame can be either open or self-contained configurations, providing a solid one-piece gate. In the case of an open frame with the operator, an operating floor located over the channel for supporting the pedestal is necessary. Stainless Steel penstocks have very good corrosion and erosion resistance and can be operated for several years with minimum maintenance.
Based on the direction of water pressure acting on the gate, the penstocks can be classified as –
- 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 stop logs 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.
