Series 200 - NPT Check Valves and
Pressure Relief Valves

Easily mounted in-line and ideal for liquid or air, our Series 200 NPT check and pressure relief valves eliminate the leak prone adapter seen in other valves by combining the fitting and check valve in one piece.

Series 200 valves are ideal for applications that require threading and involve vibrations, torquing, or any high-stress environment.

Compression fitting Model #224 is available for use with Models #212 and #214 on inlet and outlet sides. Model #214 - 1/8" size may be combined with Model #212 - 1/4" size or you can use the same NPT on both ends.

At Smart Products, all of our valves are customizable by plastic body material, o-ring material, and opening spring pressure to meet a specific application criteria.
