Nonmetallic Check Valves

Nonmetallic 1/4-28 and Inline Cartridge Check Valves

These check valves function well in both low and high pressure applications. Low internal volume also allows them to be used in areas where flow path volume is important; however, higher flows can pass through with minimal pressure drop. Metal-free composition makes the check valve perfect for use with corrosive fluids or biological samples.
