There were 24 questions found in this category:

  1. questionDo you have datasheets for your products?
    Yes, for each product line there is at least one datasheet or brochure.  To see all of the datasheets available for download click on the following link: To see the datasheet associated with a particular product, look at the Datasheet, Vide ...
  2. questionDo you have online pricing for standard components?
    We do not currently offer pricing online. However, you can go to our support page by clicking here and ask us for a quote or you can log-in to our online catalog and request a quote or place an order from there.
  3. questionDo 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 and/or assemblies below or equal to the limits in sections 1.1, 1.2, 1.3 and 2, respectively must b ...
  4. questionDo your products meet CE-PED?
    Yes, our products meet the requirements of CE-PED.
  5. questionDoes ASEPCO offer a conversion from Microinch to Micron(micrometer) for the finish on the valve bodies?
    The basic formula for conversion from microinch to micron (micrometer): 1 microinch = 0.0254 micrometer 1 micron = 39.4 microinches Some common finishes: 10 microinch Ra = .229 to .279 micron R 15 microinch Ra = .381 micron Ra 20 microinch Ra = .508 micron Ra
  6. questionDoes ASEPCO offer any type of warranty for it's products?
    Asepco offers lifetime warranties against defects in workmanship on all it's products.For a more detailed review please contact us for a copy of our warranty terms.
  7. questionHow do I get a model number if I only know the serial number of my valve or mixer?
    Call 1-800-882-3886 or email: with your serial number and we will tell you the model number of your product.
  8. questionHow do I order ASEPCO components?
    You can order parts directly through us. Click on the URL below to register for access to our online catalog: Or you can call us at: 1-800-882-3886
  9. questionHow is ASEPCO different from other companies?
    We are not just vendors. We are colleagues. We attend the workshops where our industry's technical problems are discussed. For years we have been members of I.S.P.E. and A.S.M.E. We are not only in the exhibit halls where sales people talk to each other while the real discussions take place beh ...
  10. questionHow is specific gravity different in relation to viscocity?
    Viscosity, in simple terms, is the thickness of a fluid. The higher the viscosity, the thicker the fluid. Dynamic viscosity is most commonly measured in centipoise (cps).For example, water is low viscosity (thin) 1 cps, while honey is high viscosity (thick) 2000 cps.Specific gravity is the relat ...
  11. questionI've forgotten my User Name. How do I find this out?
    Your username is the email address you used to register.
  12. questionOn an ASEPCO Tangential Valve, how can I determine if it's right or left tangent?
    To determine the position of a tangential valve hold the valve body in front of you with the outlet facing you and the inlet facing upwards: If the outlet is on the RIGHT side: Right Tangential Valve If the outlet is on the LEFT side: Left Tangential Valve
  13. questionOn what basis or market criteria was the Hydrodynamic valve design made?
    Our Hydrodynamic design was based on feedback from the market concerning temperature control and sample system cleanability.
  14. questionWe've lost/misplaced the documentation for a valve. Does ASEPCO keep documentation for the valves they've sold?
    We keep order documentation permanently.  If you require a copy of your order documents please contact us with any of these numbers: 1. The Sales Order/COC number 2. Your purchase order number 3. The valve serial number With any of these we can find your documents and send you a copy.
  15. questionWhat are "dead legs" and why must they be avoided in aseptic systems?
    A "dead leg" is a sump, or area of entrapment, in a vessel or a piping system where contamination can occur. Dead legs take longer to flush out during CIP, extending rinsing cycles, creating "cold spots" during SIP, and increasing downtime. A typical occurrence of a dead leg would be at a "tee". ...
  16. questionWhat are the Pressure Ratings for End Connections and Diaphragm Clamps?
    ASEPCO Radial Diaphragm Valves are designed for a working pressure of 250 PSI in all sizes. You have asked for a temperature rating 300° F. As far as the effect of temperature on 316L stainless steel bodies we would not downgrade the pressure rating below 250 PSI. As for the diaphragm and ...
  17. questionWhat certifications or standards do ASEPCO products comply with?
    ASME BPE - The American Society of Mechanical Engineering BioProcessing Equiment Standards - applies to all of our products when used in the Biotech industry USP Class  VI - The US Pharmacopoeia - applies to our diaphragm materials CE/ PED - The European Standard for Pressure Equipment - appli ...
  18. questionWhat does the term "behind-the-seat flowpath" mean?
    ASEPCO diaphragm valves offer the "behind-the-seat flowpath" when the valve is closed. It permits CIP/SIP flushing after each sample to clean the valve, making it ready for your next sample. When steam is flowing through a closed ASEPCO valve, it travels via the valves' "behind-the-seat flowpaths."
  19. questionWhat exactly does a solenoid valve do?
    A solenoid valve is an electro-magnetically controlled valve that has many uses. Typically, in the Biotech industry solenoid valves are used to control air operated equipment, such as valves with pneumatic actuators.
  20. questionWhat is CE?
    CE, or CE marking, stands for "Conformite Europeene" which means "European Confomrity". Following this directive means that a manufacturer's product(s) complies with the essential requirements of the relevant European health, safety and environmental legislation.
