VNE
Frequently asked questions
Common questions about VNE from 3G Electric.
What types of VNE sanitary valves are available through 3G Electric?
3G Electric stocks a range of VNE sanitary valves, including 3-A certified butterfly valves, ball valves, poppet check valves, and diaphragm valves. These are available in various sizes, typically from 1/2 inch to 4 inches, with connection options such as clamp, threaded, and butt-weld. Many valves are constructed from 316 stainless steel and meet 3-A Sanitary Standards for hygienic applications. Actuated versions, such as pneumatically actuated ball valves, are also offered for automated process control. The catalog includes over 170 SKUs, covering both manual and actuated configurations.
What does 3-A certification mean for VNE sanitary valves?
3-A certification indicates that a product meets the sanitary design standards established by 3-A Sanitary Standards, Inc., a non-profit organization that develops criteria for equipment used in the food, dairy, and pharmaceutical industries. For VNE valves, this means the design facilitates cleaning and inspection, uses appropriate materials like 316 stainless steel, and meets specified surface finish requirements. For example, VNE poppet check valves may have an average surface roughness (Ra) of 20 or 32 microinches on product-contact surfaces, while some ball valves have Ra less than 0.6 micron. These features help prevent product contamination and support clean-in-place (CIP) and sterilize-in-place (SIP) procedures.
What are the typical surface finish specifications for VNE sanitary check valves?
VNE sanitary poppet check valves are available with different surface finish specifications depending on the model. Common average surface roughness (Ra) values for the internal product-contact surfaces are 20 microinches and 32 microinches. For instance, the VNE 45C-6.5-V has a 20 Ra ID finish, while the 45C-62.0-E has a 32 micron-in Ra. These finishes are measured on the wetted surfaces and are intended to meet 3-A Sanitary Standards for cleanability. When specifying, it is important to confirm the required Ra for the specific application, as different process fluids and cleaning regimens may call for different finishes.
Can VNE sanitary valves be actuated for automated control?
Yes, VNE offers actuated sanitary valves, including pneumatically actuated ball valves and butterfly valves. These valves are designed to accept actuators and can be integrated into automated process control systems. For example, the VNE pneumatically actuated two-way ball valve (SKU 3G-OTH-437211) is a 3-A certified valve with a three-piece design and clamp x clamp connections. Note that pilot solenoids are not included with the valve and must be specified separately. Actuated valves are available in various sizes, such as 4-inch, and are constructed from 316 stainless steel. They are suitable for applications requiring remote or automated operation, such as in CIP systems or batch processing.
What connection types are available for VNE sanitary tube fittings?
VNE sanitary tube fittings are offered with several connection types to suit different piping systems. Common options include clamp ends, which allow for quick assembly and disassembly without tools; threaded ends, such as NPT or BSPT, for connection to threaded ports; and butt-weld ends for permanent, leak-free joints. Fittings may also combine different end types, such as a clamp x threaded adapter. For example, the VNE EG22-6L1.5X.75 is a straight adapter with a 1 1/2 inch OD clamp end and a 3/4 inch OD threaded end. These fittings are typically made from 316 stainless steel and comply with FISA standards. The choice of connection depends on the system design, cleaning requirements, and maintenance considerations.
How does 3G Electric support procurement of VNE sanitary components?
3G Electric supplies VNE sanitary valves and fittings to industrial customers worldwide. The company maintains inventory of over 170 VNE SKUs, including 3-A certified butterfly and ball valves, check valves, and tube fittings. For procurement specialists, 3G Electric provides product specifications, manufacturer part numbers, and compliance information to assist with verification and purchasing. The company offers global shipping and can provide quotations for specific part numbers and quantities.
