Gate valves

Gate valves

 Double air valve, providing three functions:

- High flow rate air discharge capacity for pipe-filling operation,

 - High flow rate air inlet for pipe drainage operation and in case of pipe burst,

 - Continuous evacuation of air under normal working conditions (small orifice function).

Description

  • Design:

  - Ductile iron design.

  - Patented reversible floating disc for closing under water or air flow conditions (type V1000 and V2000 only).

  - Powder epoxy and cataphoresis coating,

  - Available with or without built-in clockwise closing isolating valve,

  - Version with isolating valve :

              . 1/4 turn ball valve, with 19x19 lockable square cap on type

    . Multi turns straight mounting valve, with 30x30 square cap on types V500 and V1000.

  - Ball basket in stainless steel.

  - Lateral body boss which can be drilled on request to enable the mounting of pressure gauges

  • Performance:
