Cartridge Check Valves | Plastic & Inline Ball Check Valves

Series 100 - Cartridge Check Valves/ Pressure Relief Valves

Used for liquid or air, our cartridge check valves can be incorporated into virtually any mounting design and are easily inserted into fittings, manifolds, or installed in-line.

Recently introduced, the patented Model 101 Micro Barbed Check Valve is the smallest of its kind and is ideal for medical applications that incorporate tubing. The unique patented design features a spring-loaded poppet with a silicon ball seal and is available in a choice of opening pressures from 2 PSI to 20 PSI.

An extensive off-the-shelf, mix-and-match capability provides you with a wide range of product possibilities for designing a "custom" check valve – without a custom price. Smart Products cartridge check valve options include:

Standard, barbed, NPT, side seal, or micro barbed styles
Wide range of plastic, o-ring, and spring materials
Choice of precision opening pressures
