Ball Valve For Water Works
- By applying the Double Blocking System, it guarantees perfect sealing.
- As a full port type, it is possible to perforate without blockage of water.
- When using an existing vertical sluice valve, a deep installation depth must be secured.
- It can be installed regardless of the flow direction of the fluid. (Excellent two-way blocking ability)
- Standard
-
- 200㎜ ~ 1,650㎜ (※ 고According to customer requirements, small diameters of 1,650㎜ or less can be manufactured. )
- Working pressure
-
- 4.5kgf/㎠ ~ 20kgf/㎠
- Operation method
-
- Manual, Electric, Pneumatic Pressure, Hydraulic Pressure
- Installation method
-
- Closed in case of emergency (including check valve function - pneumatic, hydraulic)
- Opening/closing speed control (pneumatic, hydraulic)
- Perforation without water blockage
