Body vent and
drain
The drain and vent plug of the valve body enable to check the
integrity of the seat ring. A bleed valve may replace the drain
plug.
Double block and bleed
BOTELI design of a valve with two seating surface between which the
cavity can be vented through a bleed connection and thus confirm
the tightness of the valve, as well in closed position as open
positon, when pressure is applied to any side or both sides of the
valve.
Double piston effect
With the DPE seat configuration when there is a leakage in
the upstream seat, the pressure entering into the body cavity
pushed the downstream seat against the ball and the valve
seals.
This effect is a sealing principle involved in utilising line
pressure to effect a seal across the floating seat.
Self relieving seat
In self relieving condition, excessive internal body pressure is
automatically relieved both in upstream and downstream line by
forcing the seats away from the closure element.
