Design Considerations

The 1650 Series Poppet Check Valve incorporates an o-ring that is captured in a brass poppet to seal on a brass seat in the check valve body. The poppet style is an economical, general use design that provides a positive seal down to about 1/2 psi back pressure. The maximum operating pressure is 1200 psi.
