Conval's engineering team combined four WHISPERJET Assemblies with four stop valves to
create a binary throttling system. Individually the valves are never throttled but, by
opening combinations of valves, any required flow rate can be achieved. For greater
precision, WHISPERJET Valves of varying size can be combined such that a linear control
curve is approximated.
The QUADFLOW Valve was designed to eliminate these problem areas:
Seat Erosion
Severe service combined with conventional throttling led to limited valve trim life
and frequent maintenance.
Actuation
High ambient temperature and tight physical space turned conventional air operators
into high failure problems. Large heavy actuators required additional support and
vibration dampening.
Packing
While heavy cycling demands require frequent packing adjustments, high ambient
temperature and tight access space prevent maintenance efforts.
Noise
High noise levels resulted from single point pressure reduction.
