Frequently Asked Technical Questions — Stainless Steel Sanitary Butterfly Valve

Q1: What distinguishes sanitary butterfly valves from industrial butterfly valves?

A: Sanitary butterfly valves, such as the stainless steel sanitary butterfly valve, are manufactured with electropolished internal surfaces (Ra ≤0.8 um) and hygienic design. They prevent crevices where bacteria can accumulate, meeting food/health regulations (e.g., 3A, FDA).

Q2: Which steel grades are available?

A: SS304 and SS316L are most common for stainless steel sanitary butterfly valve products. SS316L offers better pitting/corrosion resistance, making it ideal for high-purity pharmaceutical or chloride-containing applications.

Q3: What is the standard sealing material used?

A: EPDM and PTFE are prevalent. EPDM is FDA-compliant and suited to food processing up to 120°C, while PTFE resists aggressive chemicals and high temperatures, ensuring a sterile shut-off.

Q4: Do these valves meet international sanitary standards?

A: Yes, when using configurations such as DIN, SMS, ISO, or ASME BPE, these valves comply with global standards for cleanable pipeline components.

Q5: What actuators can be integrated?

A: Manual handles, pneumatic actuators, and electric actuators are options. Pneumatic types are preferred for automation and remote control in process plant operations.

Q6: Are bespoke sizes or materials possible?

A: NINGJIN COUNTY HONGDA VALVE CO., LTD. accepts tailoring requests for sizes, body materials (PVDF, Duplex SS), and special elastomers to match complex process requirements.

Q7: Can a stainless steel flanged butterfly valve be directly interchanged with a wafer type?

A: No, since mounting flanges, bolt holes, and face-to-face dimensions differ. It is critical to match the valve end connections with pipeline standards to ensure proper sealing and alignment.
