Additional Information
PED Compliance Statement: Due to the unique "insert" design of our 3S, SC, CB, TC, SI, & UV, style check valves, they do not constitute an "identifiable pressure bearing housing" as defined in PED Guideline 1/8. These styles must be installed into either ferrules or fittings to create a pressure bearing housing. Instead, they are classified as "components of pressure equipment" as defined in PED Guideline 1/8. As a result, these valves can be sold in the European Community and no CE Mark is required.In addition applications where the maximum allowed operating pressure is 0.5 bar (7.2 psi) or less, do not fall under the PED, regardless of the valve style.
