Questions and answers of the customers

    can you push gas (oxygen) through this? What is minimum pressure requirement?
  1. Q can you push gas (oxygen) through this? What is minimum pressure requirement?
    A It is possible and some customers have used fittings like this in the past. The tri-clamp fittings are leakproof and cracking pressures, dependent upon the size of the valve, are located lower down on this page.
  2. For the 1.5" tri-clamp. What size and type of gasket is used to join the two halves?
  3. Q For the 1.5" tri-clamp. What size and type of gasket is used to join the two halves?
    A Our sanitary fitting sizes are universal. So for the 1 1/2" Tri-Clamp Fittings, you would choose the 1 1/2" Tri-Clamp Gasket size.
  4. What materials are the internals for this Tri-Clamp Check Valve (stopper, o-ring, spring, spider disk)?
  5. Q What materials are the internals for this Tri-Clamp Check Valve (stopper, o-ring, spring, spider ...... Read more
    A The O-Ring gasket is made of viton. All other components are 316 Stainless Steel.
  6. We need to autoclave this which is 250F, spec says max temp is 200F - can this be made autoclavable?
  7. Q We need to autoclave this which is 250F, spec says max temp is 200F - can this be made autoclavable?
    A

    The valve you are looking for would most likely need to be designed for autoclave.  The valves we offer are not designed in such a manner.  I'm sorry that we cannot be of more assistance for this one.

  8. Can we get a different o-ring than viton? We need compatibility for hydrochloric acid and sodium hydroxide.
  9. Q Can we get a different o-ring than viton? We need compatibility for hydrochloric acid and sodium ...... Read more
    A We do offer alternative o-rings for the Tri-Clamp Check Valve. Please call us for more information.
  10. Are these check valves suitable for both vertical and horizontal installations?
  11. Q Are these check valves suitable for both vertical and horizontal installations?
    A Yes, these tri-clamp check valves can be used in both vertical and horizontal installations. Please verify cracking pressure along with liquid weight which will impact the opening of check valve.
  12. What is the largest OD of the valve with the clamp used in the center?
  13. Q What is the largest OD of the valve with the clamp used in the center?
    A I'm not sure if I understand your question correctly, but the largest outside diameter tri clamp check valve that we offer is 6". Please call or email for additional information.
  14. What material is the green O-ring gasket in the check valve?
  15. Q What material is the green O-ring gasket in the check valve?
    A The O-Ring gasket in this clamp check valve is made up of Viton. Viton is a brand of synthetic rubber and fluoropolymer elastomer commonly used in O-rings, chemical-resistant gloves, and other molded or extruded goods. Viton fluoroelastomers are categorized under the ASTM D1418 and ISO 1629 designation of FKM.
  16. What is the overall length of this for 2"?
  17. Q What is the overall length of this for 2"?
    A The 2" clamp check valve measures in at 4.583" from head to toe. For other sizes and dimensions please consult our sizing chart found on the product page.
