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

 

Configuration

 

● Restriction plates (Standard applications)
● Multi-hole restriction plates (Used to reduce noise)
● Multi-stage restriction units (Flanged / Butt-weld)
● Conical shaped restriction orifice (Eliminated damage caused by cavitation)
