Penstock, wall-mounted, with rising stem, open frame, for neutral water and wastewater treatment. 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 or rectangular with resilient sealing on all four sides of the slide. They are bi-directional between and including 1300 x 1300 mm - 1500 x 2000 mm. The penstocks are with rising stem and open frame, and are designed for wall mounting. AVK wall penstocks are also available with non-rising stem and for embedding in concrete. All penstocks in the comprehensive product range feature a low leakage rate and a reliable operation.
