Restriction orifice plates are devices used to restrict flow, or for reducing pressure. It decreases pressure and flows from the upstream side to the downstream side. They protect downstream equipment and are effective at reducing noise. The design of the restriction orifice plate is very similar to an orifice plate, but the function is different. Specifically, restriction orifice plates fulfill a number of purposes including prevention of critical, controlling flow rates, reducing inline pressure and noise levelse, and removing cavitation. They are widely used for numerous applications in industries such as oil and gas, chemicals and the power industry. Choose between a single and multhole design below.
