KOENIG RESTRICTOR® SERIES RE – OVERVIEW

forward flow restrictor
Series RE flow restrictor

The KOENIG RESTRICTOR® Series RE is designed to restrict flow in fluid systems and is available in a variety of orifice sizes. These flow restrictors are tamper resistant and provide proven performance even in high-vibration applications, with a maximum working pressure of 210 bar (3045 psi) depending on the base material and part size. Series RE restrictors securely install into drilled holes with fast and easy installation, effectively controlling the flow of both fluids and gasses.

With complete design-in engineering support, and global expertise in a variety of sealing and flow control applications, SFC KOENIG is ready to assist with your orifice flow restrictor needs. To assist with part selection, we have developed a Flow Rate Calculator and an Orifice Size Calculator that can help identify which Series RE orifice restrictor fits your application requirements, or use our Product Selector to identify the best KOENIG RESTICTOR part for your specifications.
