Barbed Check Valves

SCV Series Barbed Check Valves

To Provide a Reliable Mechanical Connection

Barbed check valves feature 3/32" (2.4 mm) and 1/8" (3.2 mm) single barb ends in barb to barb straight through, reducing, and barb to male/female luer configurations. Barbed check valves reduce the risk of contamination and feature more precise, lower crack pressures and higher flow rates. They are ideal for medical device designers focused on infusion, drainage and irrigation applications.

Easily Control Flow with Barbed Check Valves

Nordson MEDICAL's barbed check valves feature more precise, lower crack pressures, and higher flow rates. Cracking pressures are ≥ 6 mBar (≥ .087 psig), and flow rate with water is ≤ 150 ml/min (≤ .0396 gal/min). With a normally closed valve position, you can get optimum flow control.

By only allowing flow in one direction and automatically preventing back flow, check valves help keep your systems clean and reduce the risk of contamination.

Barbed check valves' open and closed valve positions are controlled by the flow and do not require assistance. They also operate in any spatial orientation, so you can focus on other parts of your assembly.

Our materials also meet USP Class VI and ISO 10993 criteria. Testing results are available on request.
