XL4 penstock weir type with throttling orifice, 4-sided sealing
Opening dimensions 200 × 200 mm to 1200 × 1200 mm
Selectable pressure levels on both sides: 2-6 mwc
Frame and plate
- Throttling orifice with variable dimensions in the penstock plate
- Stroke in both directions for operation in the „Closed“, „Open“ and „Throttle“ positions
- Supplied as pre-assembled penstock which does not require assembly, setting and adjusting works
- Design as self-supporting frame construction made of stainless steel with integrated spindle bearing
- Welded frame and penstock plate made of stainless steel, optimised for maximum safety and durability by means of FEM certification
- Bridge screwed on, thereby all wear parts (spindle, spindle nut, spindle bearing and seal) can be exchanged in the installed condition without dismantling the penstock from the structure
- Integrated guide rails on the penstock plate made of polyethylene (PEUHMW)
- Penstock for embedding in concrete: Equipped with adjustment sleeves for aligning the penstock in the channel recess
- Welding certificate in accordance with DIN EN 1090-2 EXC2
Materials
- Stainless steel 1.4301 (304) / 1.4404 (316L) / 1.4410 (A182 F53) / 1.4462 (A182 F51) / Steel 1.0038 (S235JR) hot-dip galvanised or epoxy-coated
- Stainless steel spindle protection (where structurally feasible)
- Spindle with rolled trapezoidal thread made of stainless steel
- Single spindle design or twin spindle design
- Spindle nut made of seawater-resistant bronze
- Optional: Spindle outside the medium rising or non-rising (easier to lubricate)
Slide sealing system
- Integrated sliding guides on the penstock plate made of polyethylene (PE-UHMW)
Leak tightness class
- Leak rate better than DIN EN 19569, Part 4, Table 1:
- Pressure on front side max: 1 % of 0.05 to 0.1 l · s-1 · m-1 (leak tightness class 3)
- Pressure on back side max: 5 % of 0.05 to 0.1 l · s-1 · m-1 (leak tightness class 3)
