Cast iron, wafer type Butterfly valves with stainless steel disc PN 16 are a type of pipeline valves, where the closing element is in the form of a disc that rotates around its axis. This allows the valve to transition from the "open" to the "closed" position by turning 90°.

Installation 

Butterfly valves with NBR sealing are installed between flat flanges without the need for additional gaskets, simplifying the installation and removal process.

NBR Sealing

  • Nitrile butadiene rubber (NBR) is oil- and gasoline-resistant rubber.
  • Resistant to the effects of mineral oils, vegetable and animal fats, propane, butane, and gasoline.
  • Can operate in a temperature range from -30°C to +80°C.

Butterfly valves with NBR sealing are used in various industries, including:

  • Oil and gas industry.
  • Chemical industry.
