  10. Do you supply a declaration of conformity on the product that is not CE marked Do you supply a declaration of conformity on the product that is not CE marked
    No,  for products that fall under sound engineering practices (SEP) for the Pressure Equipment Directive (PED), we supply a certificate of conformance. (from Article 3 of the PED: Pressure equipment ...
  11. What is the pressure/temperature rating of an ASEPCO valve?What is the pressure/temperature rating of an ASEPCO valve?
    All valve bodies are designed to withstand pressures up to 250 PSI and temperatures up to 205° C. Note: Diaphragms can withstand temperatures up to 135° C.
  12. How come there is no CE mark on my valve?How come there is no CE mark on my valve?
    Based on the Pressure Equipment Directive (PED) the majority of our products fall under the Sound Engineering Practices (S.E.P.) of the PED. Because of this we are not allowed to place the CE mark on...
