Valves
DN350
- DN1800, PN 10
/ PN 16
Advantages In Short :
- Body Seat face as nickel weld overlay, micro finished .
- valves disc double offzdet on shafts.
- Designed for optimum hydraulic flow patterns.
- low flow coefficient.
- Endless profile sealing ring.
- Adjustment and exchange of peripheral seals are possible without removing the valve disc.
- All screws in contact with working fluid of stainless steel A-4.
- A positive, tight shut -off.
- Sealing of the disc is guaranteed for pressure from both sides.
- Suitable for flow control purposes.
- Irreversible spindle gear, corrosions resistant.
