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.
