constant flow or regulator
constant flow or regulator
(OP)
Hi,
We are revamping our clean room areas. We have to monitor the pressures in the rooms and keep them within +/- 5 Pa. What is the preferred method: constant flow valves in in- and output ducts, or use a regulating valve in the outlet duct?
Kindest Regards,
Marco Bakker

RE: constant flow or regulator
Constant flow dampers are cheaper option but they take time to stabilize once the pressure balancing gets disturbed.
Modulating control dampers should be controlled by a room pressure transmitter and position of the sensor inside the room is very critical.
