throttling orifice plate
Thread Content
When using a flow-limiting orifice plate instead of a valve to regulate flow, how can the flow rate be ensured? Please give some advice. Thank you
As long as the pressures before and after the flow control orifice plate remain stable, the flow rate will remain stable.
Which one better meets the process requirements: a flow control valve or a regulating valve? The control valve is monitored and adjusted in real time via PID. Rate limiting definitely won’t suffice.
The flow-limiting orifice plate is a simple flow-control element, belonging to the process engineering field； Control valves are complex instrumentation devices that fall under the field of instrumentation.
Price: Orifice plates are inexpensive ； Control valves are expensive. In terms of adjustability: orifice plates are not adjustable, while control valves are adjustable. It depends on the application – in situations where flow regulation is needed, control valves should be used ； Other available orifice plates
It depends on whether you require high precision in terms of flow rate. If the requirements aren’t strict, control the pressure difference before and after the throttle orifice to keep the pressures stable. If higher precision is needed, then use a control valve; of course, such valves come at a higher cost
