Product Overview
Introducing the D71X Stainless Steel Wafer Butterfly Valve, a masterfully engineered valve designed for exceptional performance in a variety of demanding applications. Its centrically designed structure ensures swift and efficient opening and closing, offering seamless flow regulation. Built to be compact and robust in sealing, this versatile valve finds its place across multiple industries including water treatment, chemicals, food, and pharmaceuticals. It stands out as the ideal choice for handling corrosive media or high-purity environments.
Model Breakdown
- D: Represents the Butterfly Valve
- 7: Indicates Wafer Connection
- 1: Refers to Centric Design (Valve Disc Rotates on Central Axis)
- X: Specifies Rubber Seat Material (e.g., EPDM, NBR, etc.)
Structure & Materials
- Constructed with high-quality stainless steel options (304, 316, or 316L) for excellent corrosion resistance, the body, disc, and stem promise durability and reliability.
- The Seat Ring is crafted from flexible rubber materials, with EPDM as standard, offering a temperature range of -20°C~120°C. Optional materials like NBR and Fluorocarbon are available for specific media needs.
- Actuation options are versatile, featuring manual operation via lever or gear, and customizable pneumatic or electric actuators to match specific operational requirements.
Working Principle
The valve disc is precisely engineered to rotate 90° through the stem, effectively controlling fluid flow. Its centric design ensures consistent contact between the disc and seat, facilitating reliable bidirectional sealing with minimal leakage, even under low-pressure differentials.
Key Feature
- Corrosion Resistance: A blend of stainless steel and rubber sealing makes it perfect for challenging acidic and alkaline environments.
- Low Flow Resistance: The full-bore design significantly reduces pressure loss, enhancing efficiency.
- Lightweight & Durable: With a compact structure and weighing only one-third of conventional gate valves, it ensures ease of maintenance.
- Rapid Operation: A quick 90° rotation allows for efficient manual or automated control, ensuring swift responsiveness.
- Temperature Range: Adaptable from -20°C to 180°C, depending on seat material selection.
Applications
- Water Treatment: Ideal for water supply systems, drainage, firefighting, and wastewater management.
- Industrial Piping: Suitable for chemical, petroleum, gas, and HVAC industries.
- Food & Pharma: Available in sanitary-grade options with polished surfaces, fully compliant with GMP standards for utmost safety and hygiene.
Installation & Maintenance
- Installation: Ensure compatibility with matching flanges and tighten bolts symmetrically to protect the seat from damage.
- Maintenance: Regular inspections are advised for seat wear and stem lubrication. Seal replacements should occur every 3-5 years, contingent upon service conditions.
Precautions
- Avoid exceeding recommended pressure and temperature limits to maintain seal integrity.
- Install a filter to safeguard against media containing hard particles.
- Rubber seats are not compatible with strong oxidizers like concentrated sulfuric acid; select materials wisely for aggressive media.
Optional Configurations:
- Explore alternative seat materials such as PTFE for enhanced high-temperature resistance.
- Extended stems are available for insulated pipelines or special installation scenarios.
- Locking devices can be added to prevent unintended operations, ensuring safety and control.
