Penstocks have many applications in the arrest and control of liquid flow. They are used on Waterways, Power plants, Industrial effluent plants, hydro power, Drainage and Flood control as well as being used in large numbers on water, waste water and sewage treatment plants.
Penstocks, unlike valves, are normally fitted into or onto the civil structure formwork either in channels or over an aperture in a wall. The channels and apertures are sized to accept a range of flow situations and the penstocks are required to suit. This requirement alone dictates that they are a bespoke product.
- Penstock type - Open, shut, modulating, weir
- Mounting configuration - Channel, Wall
- Seating direction - On, Off
- Pressure - Static, Operational
- Operation/Operator - Manual, Prime mover, (electric, pneumatic, hydraulic)
Our standard range includes sizes from 100mm to more than 4000mm, but each Waterfront penstock is individually designed to specific customer requirements and a general arrangement drawing produced for approval prior (if required) to manufacture. Following initial selection, thrust and torque values are calculated in order to determine the operating equipment size. Channel penstocks normally operate at door depth pressure, but wall mounted penstocks of both HDPE and fabricated construction can be subject to very high pressures.
Standard HDPE penstocks are either circular or square, however non standard sizes can be accommodated upon request. Fabricated penstocks can be designed and manufactured to any rectangular or square size. We will be pleased to discuss any general or specific requirements you may have.
A range of Handstops and Stoplogs are available for lighter duties and temporary damming applications. These are made to the same high standards as the penstocks and can be provided in a range of materials – please see the relevant section for more details.
