AWMA’s TLF Penstock range consists of an undershot gate with a full perimeter seal, providing flow isolation for fully submerged on or off seating applications.
FEATURES
- Resilient seals around all four sides of the aperture.
- Excellent sealing for medium head applications.
- Suitable for flow regulation applications.
- Seals are bi-directional as standard.
- Both rising and non-rising spindle configurations available.
- Frame customised to suit application.
APPLICATIONS
- Full perimeter seal provides excellent sealing performance for applications across all industry sectors.
- Isolation of pipe openings and orifices over 300mm in diameter.
SIZES
- AWMA offer a range of standard size TLF penstocks to suit typical pipe and culvert openings.
- If required, AWMA can provide a customised solution for non-standard applications.
MATERIALS
- AWMA TLF penstocks are typically manufactured from marine grade aluminium or stainless steel (grades 304, 316, 2205 or 2507).
- Material selection is discussed with clients to determine the most appropriate material for the application.
- Seals are mechanically fastened (non-adhesive) and are designed for ease of replacement.
- AWMA utilise plasticised PVC and/or EPDM seals due to their superior performance in a range of environments including stormwater, wastewater and sea water.
- Ultra-high molecular weight polyethylene (UHMWPE) is used for TLF penstock guides and seal retainers. UHMWPE is a hard wearing, low friction material that is ideal for bearing surfaces and the prevention of metal-metal sliding contact or the isolation of dissimilar metals.
