- The adjustable orifice plate is used to adjust flow rates at constant pressure. To change the flow rate, the valve plate can be twisted to expand or narrow the opening.
- If the opening is expanded at constant pressure, the flow rate through the orifice plate increases.
- On the other hand, if the opening is narrowed at a constant pressure, the flow rate decreases. Recommended measurement and flow-calming sections before and after the orifice plate: 2–3 x DN.
- An adjustable wrench is available to adjust the orifice plate more easily. (See accessories) The orifice plate cannot be used as a shut-off valve (cannot be closed 100%).
