The 1-1/2" SI Style Insert Check Valve offers a reliable solution for applications requiring a threadless valve with a standard cracking pressure of 3.50 psi. Made in the USA, this valve, available in various body materials, can be used as a low-pressure relief valve or vacuum breaker with customizable spring settings. With non-shock pressure ratings of 3000 psig, it complies with ISO 9001 standards and is PED compliant for European Community sales without the need for a CE Mark.

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.
Note
Made in USA.
