Questions & Answers 6

Questions and answers of the customers

  1. Q When partially open, does the valve have 'stops' or lock-locations, or is it infinitely adjustable between open and close?
    A The tri-clamp butterfly valve with a pull handle has four (4) locking locations. Alternatively, our Trigger Handle Butterfly Valve has twelve (12) locking locations.
  2. Q Is this valve NSF61 certified for water?
    A This is not a sanitary document we can provide for any of our valves.
  3. Q What is the max pressure for a 1”?
    A The pressure rating on the 1" Tri-Clamp Butterfly Valve is 140PSI.
  4. Q What is the max pressure for a 1”?
    A

    This valve has been tested to a pressure of 140PSI for the 1" version.

  5. Q Will this valve leak if one side is placed under vacuum and the other side is exposed to air?
    A These valves are designed to withstand a certain amount of pressure both internal and external. At some point, the valve will fail under pressure but it all depends on the strength of the vacuum you are applying.
  6. Q What is the seat material of these valves? Also, do you know the recommended temperature range?
    A The seat material for our tri-clamp butterfly valves is EPDM. We also can offer this in Viton. Regarding the temperature range, EPDM is rated to temperatures of +250°F.
