Spesifikasi
|
|
Medium
|
Water, Wastewater, Slurries, Sewage, Fluids with Solids
|
|
Operating Temp.
|
-20°C ~ +100°C (EPDM Lining)
|
|
Max Operating Pressure
|
Up to 200 psi / 16 bar (Depending on pressure class)
|
|
Flow Direction
|
Horizontal or Vertical Upwards (Ball lifts to open)
|
|
Pengedap
|
