PENSTOCK, CLOSED FRAME, NON-RISING STEM
Bi-directional, 10m or 6m head, wall-mounted, 304 frame/gate and stem, EPDM seal, type MU14 (MU20)
Penstock, wall-mounted, with non-rising stem, closed frame, for neutral water and wastewater treatment.
Note:
This datasheet shows only a small selection of sizes in the bare shaft execution. Since all valves are manufactured to customer's specifications with reference to size, actuation, material combination, pressure, etc. we recommend to contact AVK before ordering.
Wall-mounted penstocks are square, round & rectangular or round base with resilient sealing on all four sides of the slide, bi-directional flow up to and including 1200 x 1200 mm. The closed frame is designed for wall mounting or for embedding in concrete. Operation with non-rising stem. All penstocks in the comprehensive product range feature low leakage rate and reliable operation.
| Variant 772/61-005 | |
|---|---|
| Connection: | Wall mounting - concrete |
| Material: | Stainless steel |
| DN: | DN200 - DN1200 |
Features
- Frame design allows for easy mounting at medium height or floor level for flush bottom installation
- Suitable for actuation with manual, electric, pneumatic or hydraulic actuators
- Frame, slide and stem of stainless steel AISI 304
- Leakage rate less than 1.24 liter/min/seal meter (AWWA C-561)
- Four-sided sealing. Seal and guides bolting completely separated from the frame anchoring. Seal design is self adjusting (wedge-less design) to reduce torque requirements and to achieve minimal seating and unseating leakage rates. Slide ribs are designed to avoid crevice corrosion
- All gate fasteners are stainless steel
- Self-adjusting EPDM lip seal installed on the frame
- Self-cleaning guides in UHMWPE reducing friction coefficient during operation resulting in easy operation and extended seal durability
- The penstocks are factory assembled and tested to eliminate the need for on site adjustment
