Blow down ring in safety valve
WebThe decreased blowdown (nozzle) ring is common in many valves where tighter overpressure and blowdown conditions require a more sophisticated built solution. Usually the upper blowdown ring is factory set and fundamentally removes the fabrication tolerances that influence the huddling chamber’s geometry.
