Restriction orifice plate_F400 series_F400, F410, F420, F430
Type: F400
 
Description
 
Restriction orifice plates are widely used for many applications within the industry. Although the design is very similar to an orifice plate, the function is different. Restriction plates are used to suit a number of different purposes including.
 
● Reduction in line pressure
● Control flow rates by restricting flow, regardless of downstream conditions
 
			
						
Design considerations
			
 
											
● Prevent critical flow
			● Removal of cavitation
			● Reduce noise levels
			We offer a number of different restriction designs to suit the needs of your application
