The screw and auger type drive gives a slow controlled travel so the disc opens against pressure without slamming and without shock loading the pipework. The valve is built in bronze, steel or copper, polished and tested before dispatch, and can be supplied in electric or hydraulic form.

Selection notes

  • Screw and auger drive for controlled opening against differential pressure
  • Avoids slam and shock loading in the surrounding pipework
