Whilst leakage on penstocks is usually caused by insufficient frame stability and frame distortions SAFOX® patented sealing system is not affected by such parameters as it is separated from the frame. Due to this separation SAFOX® perfectly seals to the mounting wall and sliding plate and is even able to level structural variations. The freely suspended sealing ring is self-adjusting and does not require adjustment of wedges after mounting.
SAFOX® penstocks are non-drip leak proof under seating and unseating pressure and withstand water heads of up to 10 m. When required SAFOX® can be designed to withstand higher water heads.
- Nominal size: 150 mm to 3000 mm
- Pressure: up to 1,0 bar
- For round openings, mounting with chemical anchor bolts
- Leak tightness class A, SUPERIORLY TIGHT up to 10 m seating and unseating heads (standard) in accordance with EN 12266-1, Table A.5, leakage rate C. Higher pressure resistance available on request.
- Seating heads in the standard design:
- DN 150 to DN 300 10 m WC
- DN 400 to DN 800 8 m WC
- DN 900 to DN 1000 7 m WC
- bigger than DN 1200 6 m WC
- Compact design, one-unit delivery, ready to install
- Quick & easy mounting with few chemical anchor bolts. No assembly, adjustments and setting works on site necessary
- No chemical anchor bolts in bottom area
- Quickly available on site as delivery ex-stock
- Throughout the entire stroke vibration-free led gate. This allows the SAFOX to be operated in intermediate position and as a throttle valve
- Minimal closing and opening torque
- Maintenance free
- Wear parts and sealing simply exchangeably
- Maximum corrosion resistance due to stainless steel material, all acid bath cleaned and passivated
