Reliable Flow Control for Demanding IndustriesOur stainless steel butterfly valve delivers dependable performance for applications such as water treatment, HVAC systems, and industrial pipelines. With options in disc and stem materials tailored to various media, these valves ensure durability and flexibility under medium pressures and varying temperatures, supported by international end connection standards.
Superior Sealing with EPDM/PTFEUtilizing either EPDM or PTFE for the seat, paired with a bubble-tight Class VI leakage rating, our butterfly valves offer optimal sealing even in challenging environments. The valve is engineered to meet API 609 and ISO 5752 standards, maintaining performance integrity over extended use.
FAQ's of stainless Steel Butterfly valve:
Q: How does a gear-operated stainless steel butterfly valve work?
A: A gear-operated butterfly valve uses a manual gear mechanism to rotate the disc by a quarter turn, allowing precise control over flow rate or complete shutoff. The gear system provides mechanical advantage, which is helpful for larger valves or higher pressure lines.
Q: What are the main benefits of using EPDM or PTFE as seal materials?
A: EPDM seals provide excellent resistance to water, steam, and mild chemicals, making them ideal for water treatment and HVAC applications. PTFE seals offer superior chemical and temperature resistance, suitable for aggressive industrial media, ensuring long-lasting performance and minimal leakage.
Q: When should you choose stainless steel 304 versus 316 for the valve disc?
A: Choose stainless steel 304 for general applications where corrosion is moderate. Opt for 316 when higher corrosion resistance is required, such as in saline, acidic, or highly corrosive environments, to extend the service life of the valve.
Q: Where can these butterfly valves be installed and used?
A: These valves are suitable for installation in water treatment facilities, HVAC systems, or industrial pipeline networks that transport water, gas, or oil. Their versatility allows them to fit systems built to ANSI, DIN, JIS, or BS standards.
Q: What is the process for selecting the correct port size and connection standard?
A: Port size selection depends on your pipeline diameter-available from DN100 to DN2000 and customizable as needed. The connection standard should match your existing pipeline system (ANSI, DIN, JIS, or BS) to ensure compatibility and secure installation.
Q: How does the epoxy painted or powder coated body benefit valve longevity?
A: Epoxy painted or powder coated finishes protect the valve body from corrosion, abrasion, and environmental degradation. This additional coating ensures the valve withstands harsh operating conditions and maintains its performance over time.
