PENSTOCK, CLOSED FRAME, NON-RISING STEM
Bi-directional, 6m on-seat and 4m off-seat head, wall-mounted, 304 frame/gate and stem, EPDM seal, type MU14XL
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 between and including 1300 x 1300 mm - 1500 x 2000 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 772/61-006 | |
|---|---|
