DIXON
Frequently asked questions
Common questions about DIXON from 3G Electric.
What certifications do DIXON butterfly valves carry?
The DIXON butterfly valves supplied by 3G Electric are 3-A Certified, which is a standard for sanitary equipment used in dairy, food, and beverage processing. This certification ensures the valve design meets criteria for cleanability, material compatibility, and surface finish. The valves have an average surface roughness (Ra) of ≤ 32 microinches, supporting hygiene requirements. No other certifications are listed for these specific models.
What materials are used in DIXON butterfly valve construction?
DIXON butterfly valves feature a 316L stainless steel body and disc. 316L is a low-carbon variant of 316 stainless steel, offering improved corrosion resistance, particularly in welded areas. The seat material is EPDM (ethylene propylene diene monomer) for models like the B5107E400CC-C, which provides resistance to hot water, steam, and mild chemicals. The handle is typically lever-type, made from materials compatible with the valve body.
What pipe sizes and connection types are available for DIXON butterfly valves?
DIXON butterfly valves are available in pipe sizes from 1/2 inch to 4 inches. Connection types include clamp (tri-clamp) and solder ends. Clamp connections are common in sanitary applications for quick disassembly, while solder connections are used in permanent piping systems. Each size and connection type has a specific maximum pressure rating, ranging from 85 psi to 140 psi CWP.
How many stop positions do DIXON butterfly valve handles have?
DIXON butterfly valve lever handles come with either 4 stop positions or unlimited stop positions, depending on the model. For example, the 1/2-inch solder valve (MPN B5107E050BB-A) has 4 stop positions, while the 2-inch solder valve (MPN B5107V200BB-B) has unlimited stop positions. This allows for either fixed flow settings or continuous adjustment, depending on application needs.
What is the maximum pressure rating for DIXON butterfly valves?
The maximum pressure rating for DIXON butterfly valves varies by pipe size and connection type. For example, the 4-inch clamp valve (MPN B5107E400CC-C) is rated to 85 psi CWP, while the 2-inch solder valve (MPN B5107V200BB-B) is rated to 140 psi CWP. Always verify the specific model's pressure rating against your system requirements before installation.
Can DIXON butterfly valves be used in CIP (clean-in-place) systems?
Yes, DIXON butterfly valves with 3-A Certification and 316L stainless steel construction are suitable for CIP systems. The average surface roughness of ≤ 32 microinches meets sanitary standards for cleaning. The EPDM seat material can withstand typical CIP temperatures and chemicals. However, verify compatibility with your specific cleaning agents and temperature cycles.
