Why isn't there any labeling on the VT05?
There are two reasons VT05 diaphragms are not currently labeled. Under our old labeling system which consisted of "plugs" with labels as part of the mold no 0.5" diaphragms were labeled because the m...
- What tests do you perform on your diaphragms and can you send certificates of the tests?
Currently, we test our diaphragms to ensure they comply with USP VI. If you require a certificate of conformance for USP VI that can be supplied with your on request. If you require other tests, ple...
- Do you have any diaphragms that can be used with Heptane?
We currently have two diaphragms that have limited resistance to Heptane. The first is EPDM Plus which has been shown to have approximately two weeks of life when continuously exposed to Heptane. Th...
- Do you offer teflon diaphragms?
...ing issues due to "cold flow" in the
material that makes it a poor sealing material. We do offer diaphragms
(EPDM Plus, Silicone Plus) that have a surface treatment that gives some of the positive...
- How thick is the parylene surface of your diaphragms?
The thickness is .002" (.05mm).
- What are parylene diaphragms? and what are the benefits?
We currently offer two diaphragms that contain parylene: Silicone Plus and EPDM Plus. Parylene
is a material that mechanically bonds itself to the base
elastomer. Parylene is similar to teflon in...
- Why don't you offer 3" viton diaphragms?
Due to the material differences between Silicone or EPDM and Viton we would be required to make a different mold. Molds are very expensive and the current demand for 3" Viton cannot support the cost o...
- 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.
- Do I need to have continuous steam on an ASEPCO valve for sterility?
ASEPCO diaphragms are designed for SIP applications but NOT for continuous steam exposure.
- What is the temperature range for an Asepco diaphragm?
Our temperature ranges for our diaphragms are: Silicone: -40 to 135 C (-40 to 275 F) EPDM: -40 to 135 C (-40 to 275 F) Viton: -17 to 204 C (0 to 400 F) [Note: This material is not intended fo...
- What type of Parylene do you use on your diaphagms?
We use Type N Parylene on our diaphragms.
- Are ASEPCO diaphragms USP Class VI?
Yes, all of these diaphragm materials meet USP VI: Silicone EPDM Silicone Plus EPDM Plus If you would like an example of a USP VI Certificate of Conformance, just email a request to: info@asepco.co...
- Why don't you have a teflon diaphragm
...e to "cold flow" in the
material that makes it a poor sealing material for our valves. We do offer diaphragms
that have a surface treatment that gives some of the positive
properties of Teflon with...
- What is the difference between a tank valve and a process valve?
Tank valves and Process valves function identically and use the same diaphragms and actuators. Tank valves are welded into tanks permanently. Process valve inlets are hygienic (tri-clamp) clamps and...
- Does ASEPCO permanently label their valves and actuators?
Valve bodies are permanently labeled with serial and material heat numbers via pin stamping.
Actuators are permanently labeled with serial numbers.
1"-3" Diaphragms are molded with a batch number ...
- Is the ASEPCO valve designed for steam applications?
ASEPCO diaphragms are designed for SIP applications but NOT for
continuous steam exposure (Viton does not fair well under any steam
applications).
- How often should I change my diaphragms?
The answer 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...
- Why doesn't ASEPCO offer an option for an expediting fee?
.... However, you should keep two things in mind: 1. If you are ordering replacement parts, such as diaphragms, they are often in stock. 2. We do keep a stock of some standard valves in inventory. ...
- How do I return a diaphragm for evaluation
Fill in the attached form and return it with your diaphragm
- What Grade is your Viton?
We currently offer non-steam grade Viton A.
