Principle Features

  • Tested according to BS:7350.
  • Oblique Seats offer precise regulation and a resistance lower than the valve with a straight seat.
  • Head losses are small, which for a same DN leads to more important flows than those borne by a straight seal valve.
  • Tolerance on nominal Kv for fully open valve + 10%.
  • Provided with mounted test points (1/4” female thread).
  • Positive shot-off achieved by PTFE seal / Disc.
  • Tamper proof setting.
  • Screwed female end as per IS 554 / BS 21.
