About Sanitary Butterfly Valves
Sanitary Butterfly Valves
Dairy Pharma Chem one of the market leaders in Valve Solutions, butterfly valves, and iris valves. These are specially designed to handle dry bulk solids like dry foods, pharmaceuticals, chemicals, pastes, etc. The industrial butterfly valves manufactured by us can be manually operated or be operated through Pneumatic Actuator. The valves can be customized on various factors like type of seals, material used for manufacture etc. These valves are made in accordance with international standards.
- Manual Operated or with Pneumatic Actuator
- Silicon seal as standard-other seals available
- Max. working press.-2 bar
- Tri-Clamp connection with clamp, Gasket, & Blind for vacuum application.
DPL also offers iris valves with variety of configurations such as:
- Single Lock Iris Diaphragm valves.
- Double Lock Iris Diaphragm valves.
- Iris valves with Triclover connection.
- Iris valves with Pneumatics Actuator.
Diaphragm for iris valves can be manufactured from many materials as follows as per the uses:
- NylonFor handling granules or lumpy materials.
- Rubber-For handling fine, light or abrasive materials.
- Fabrics with a coating of PU (Polyurethane) or similar- For handling fine heavy powder.
Material Of Construction:
- Iris Valves / Butterfly valves are available in S.S. 316 / S.S. 304 / Aluminum alloy etc.
Hygienic Surface Finish and ConstructionDesigned for the highest standards in sanitary applications, this butterfly valve features a polished surface with roughness Ra 0.8m, minimizing contamination risks and simplifying cleaning. The body and disc use SS316L or SS304 stainless steel to provide corrosion resistance and durability in demanding environments.
Versatile Operation and InstallationChoose from manual lever handle, pneumatic, or electric actuators, each facilitating precise control. The valve can be installed horizontally or vertically, adapting seamlessly to your piping layout. End connection options include Tri-Clamp, weld, threaded, or flanged, supporting versatile integration into existing systems.
Tool-Free Maintenance and Reliable SealingMaintenance is straightforward, with tool-less assembly and disassembly speeding up cleaning and reducing downtime. Sealing components (EPDM, silicone, or PTFE) comply with FDA 21CFR177.2600, while the design guarantees zero leakage under rated pressure for assured safety and product integrity.
FAQs of Sanitary Butterfly Valves:
Q: How does the sanitary butterfly valve ensure hygienic operation in fluid control systems?
A: This valves polished surface finish (Ra 0.8m), robust stainless steel construction, and FDA-compliant seals prevent contamination and facilitate effective cleaning, making it ideal for sanitary processes.
Q: What types of actuators are available for operating the sanitary butterfly valve?
A: You can select manual lever handles, pneumatic actuators, or electric actuators (with voltage options 24V/110V/220V), offering flexible control tailored to your systems requirements.
Q: When should tool-free assembly and disassembly be utilized?
A: Tool-free design benefits cleaning or maintenance schedules, enabling fast and easy servicing without the need for specialized tools, thus minimizing downtime in sanitary environments.
Q: Where can these sanitary butterfly valves be installed?
A: These valves are suitable for horizontal or vertical piping in the food, beverage, dairy, pharmaceutical, and cosmetic industries, due to their versatile mounting options and hygienic features.
Q: What is the process for selecting the right end connection for my application?
A: Choose Tri-Clamp for rapid assembly/disassembly, welding for permanent installation, threaded for flexible connection, or flanged for robust sealing, depending on your systems design and cleaning needs.
Q: What benefits does a full-port, unrestricted flow butterfly valve provide?
A: The full port design with a smooth flow path minimizes pressure drop and ensures maximum flow efficiency, which is especially important in processes requiring gentle fluid handling or high sanitation.
Q: How does the valve guarantee zero leakage under pressure?
A: Carefully engineered sealing (using FDA-approved EPDM, silicone, or PTFE gaskets) and precise disc alignment ensure no leakage under the rated pressure, safeguarding process integrity and safety.
