FLOW RESTRICTORS

Well-suited for deep-hole locations, the KOENIG RESTRICTOR is a proven, cost-effective orifice flow restrictor that can be configured for your requirements. This one-piece flow restrictor features a durable, stainless steel construction and is available in a variety of sizes and pressures.

Since they do not require thread machining, reaming, sealants or adhesive compounds, our flow restrictor solutions reduce the risk of contamination and provide substantial savings in production and labor costs. They utilize a one-piece design that allows for easy installation, even in automated manufacturing environments, and effectively prevent side leakage. SFC KOENIG flow restrictors safely and securely withstand vibration and high-pressure environments, and if needed, even offer an easy removal procedure.

Pressure rated up to 200 bar, our KOENIG RESTRICTOR models accommodate orifice diameters as small as 0.020 inch. A screened flow restrictor option designed to protect smaller orifice diameters is also available.

The KOENIG RESTRICTOR flow control solution offers models and options to meet many flow and orifice restriction application requirements.

FLOW RESTRICTOR & CHECK VALVE INSTALLATION

Both the KOENIG RESTRICTOR and the KOENIG CHECK VALVE easily install into an as-drilled hole. The flow restrictor or check valve is dropped into a counter-bored hole and then the product’s integrated pin is pushed inside to expand the sleeve. The grooves on the outside of the sleeve anchor into the base material, providing a clean installation and precise flow control.
