    We have found that the majority of the time a user is having sealing issues is due to incorrect diaphragm installation. Attached are instructions that come with each diaphragm, make sure they ...
  6. What spare parts are available for Manual 0.5" satellite valves?What spare parts are available for Manual 0.5" satellite valves?
    There are several types of spare parts available: Diaphragms: SG05 - 0.5" Silicone diaphragm, satellite EG05 - 0.5" EPDM diaphragm, satellite VG05 - 0.5" Viton A diaphragm, satellite - not for stea...
  7. What Diaphragm material is best for steam applications?What Diaphragm material is best for steam applications?
    The best diaphragm material to choose for a steam application depends on the amount and kind of steaming you are doing, as well as other factors in your process. Constant steam exposure is much harder...
  8. Why don't you have a Teflon diaphragm?Why don't you have a Teflon diaphragm?
    In 2013 we started producing a PTFE (Teflon) diaphragm for our Tank Valves. PTFE diaphragms are available for 1.0, 1.5, 2.0, and 3.0-inch tank valves. We currently don't have PTFE diaphragms for our...
  9. How often should I change my diaphragms?How often should I change my diaphragms?
    ...swer to this question is unique to each application.  Because of the number of factors that affect diaphragm life, such as diaphragm material, SIP cycle and temperature, CIP cycle, CIP solution, and ...
  10. Do you have any diaphragms that can be used with Heptane?Do you have any diaphragms that can be used with Heptane?
    We have a PTFE diaphragm that is resistant to Heptane. This diaphragm is available only for our 1-in, 1.5-in, 2-in, and 3-in Tank Valves. PTFE is not an elastomer, and therefore, it doesn’t stre...
  11. What is the surface area of a 2" diaphragm, model VA20?What is the surface area of a 2" diaphragm, model VA20?
    The surface of the product contact area of a VA20 diaphragm is 21.2 square inches. The entire surface area of the diaphragm is 71.6 square inches.
