25S Series - Stainless Steel Penstock
The 25S stainless steel penstock range is a high quality, engineered to order product, designed to suit medium head duties. They are suitable for water and wastewater applications where flow isolation or diversion is required by way of manual or powered operation.
The 25S range consists of a robust stainless steel frame designed to withstand the specified maximum on and off-seating pressures and operating forces. Seals are frame mounted and consist of self-adjusting, ultra high molecular weight polyethylene side seals with a resilient neoprene flush invert seal or UHMWPE invert seal for downward opening weir penstocks. To achieve full perimeter sealing the 25S-T model incorporates a self-adjusting UHMWPE top seal. All seals are mechanically fixed and are easily replaceable. The stainless steel sliding gate is designed and suitably stiffened to withstand the specified pressures. 25S range penstocks are fabricated using grade 316/316L stainless steel. However, these may also be supplied using grade 304 stainless steel, duplex or super duplex stainless steels. These materials provide excellent corrosion resistance while the self adjusting UHMWPE seals provide optimum sealing and a low co-efficient of sliding friction during gate operation.
The 25S range is suitable for upward opening (25S-T), downward opening (25S-W) or sideward opening (25S-S) applications and are designed for operation by manual, electric, hydraulic or pneumatic actuators with a rising or non-rising stem. The 25S range can be supplied as fully self-contained, self contained with thrust tube, or open top with operator support pedestal. All mounting types such as wall, side wall, embedded and flange can be accommodated. Flat backed with sealing gasket for applications such as tank mounting are also available.

25A-Marine Grade Aluminium Penstock
The 25A marine grade aluminium penstock range is a high quality, engineered to order product, designed to suit medium head duties. They are suitable for water and wastewater applications where flow isolation or diversion is required by way of manual or powered operation.
The 25A range consists of a robust marine grade aluminium frame designed to withstand the specified maximum on and off-seating pressures and operating forces. Seals are frame mounted and consist of self-adjusting, ultra high molecular weight polyethylene side seals with a resilient neoprene flush invert seal or UHMWPE for downward opening weir penstocks. To achieve full perimeter sealing the 25A-T penstock incorporates a self-adjusting UHMWPE top seal. All seals are mechanically fixed and are easily replaceable. The marine grade aluminium sliding gate is designed and suitably stiffened to withstand the specified pressures. The marine grade aluminium construction provides excellent corrosion resistance while the self adjusting UHMWPE seals provide optimum sealing and a low co-efficient of sliding friction during gate operation.
The 25A range is suitable for upward opening (25A-T), downward opening (25A-W) or sideward opening (25A-S) applications and are designed for operation by manual, electric, hydraulic or pneumatic actuators with a rising or non-rising stem. The 25A range can be supplied as fully self-contained, self contained with thrust tube, or open top with operator support pedestal. The flat back design is suitable for tank mounting and can be supplied as wall, side wall, embedded or flange mounted.

US Series Penstock
The US series penstock is a high quality, engineered to order product, designed to suit a head no greater than the gate depth. They are suitable for water and wastewater applications where flow isolation or diversion is required by way of manual or powered operation.
The US penstock consists of a special channel section frame designed to withstand specified maximum on and off-seating pressures and operating forces. The frame encapsulates self-adjusting, ultra high molecular weight polyethylene side seals and the resilient neoprene flush invert seal. All seals are easily replaceable. The sliding gate is designed and suitably stiffened to withstand the specified pressures. The US series penstock is fabricated using either marine grade aluminium (USAA) or grade 316/316L stainless steel (USSS) providing excellent corrosion resistance. The self adjusting UHMWPE seals provide optimum sealing and a low co-efficient of sliding friction during gate operation.
The US series penstock is suitable for upward opening applications and is designed for operation by manual, electric, hydraulic or pneumatic actuators with a rising or non-rising stem. The US Series are supplied as fully self-contained and can be either embedded, wall or side wall mounted.
Option: Series USS wall mounted version
