Comprehensive Product Overview
Introducing the D71X Stainless Steel Wafer Butterfly Valve, a meticulously engineered centrically designed marvel that features wafer-type connections for swift opening and closing, as well as precise flow regulation. Its compact architecture and dependable sealing make it indispensable across diverse sectors, including water treatment, chemical, food, pharmaceutical, and more. This valve shines in environments with corrosive media or applications demanding high purity.
Detailed Model Breakdown
- D: Symbolizes the Butterfly Valve
- 7: Represents the Wafer Connection
- 1: Embodies Centric Design (Valve Disc Rotates on a Central Axis)
- X: Indicates Rubber Seat Material (options include EPDM, NBR, etc.)
Innovative Structure & Materials
- Body/Disc/Stem: Crafted from premium stainless steel (304, 316, or 316L) for unparalleled corrosion resistance.
- Seat Ring: Composed of high-quality rubber material (default being EPDM, with a temperature capacity ranging from -20°C to 120°C; options for NBR, Fluorocarbon, etc., available for specific media).
- Actuation: Available in manual (lever or gear-operated) forms, or customizable pneumatic/electric actuators tailored to your needs.
Innovative Working Principle
The valve disc executes a 90° rotation via the stem to regulate fluid dynamics. Its centric design facilitates uniform contact between the disc and seat, enabling reliable bidirectional sealing with minimal leakage, even under low-pressure differentials.
Distinguished Key Features
- Unmatched Corrosion Resistance: Stainless steel coupled with rubber sealing makes it ideal for acidic and alkaline environments.
- Reduced Flow Resistance: The full-bore design significantly minimizes pressure loss.
- Exceptional Lightweight & Durability: Its compact structure weighs a mere 1/3 compared to gate valves, ensuring low maintenance needs.
- Swift Operation: Experience quick manual or automated control with a smooth 90° rotation.
- Versatile Temperature Range: Spanning from -20°C to 180°C (dependent on seat material).
Diverse Applications
- Water Treatment: Optimized for water supply, drainage, firefighting, and wastewater systems.
- Industrial Piping: Ideal for chemical, petroleum, gas, and HVAC systems.
- Food & Pharma: Designed with sanitary-grade options and polished surfaces, meeting GMP standards effortlessly.
Effortless Installation & Maintenance
- Installation: Ensure compatibility with matching flanges and symmetrically tighten bolts to safeguard the seat.
- Maintenance: Conduct regular inspections of seat wear and stem lubrication; seals should be replaced every 3-5 years, based on service conditions.
Important Precautions
- Guard against overpressure or excessive temperatures to maintain seal integrity.
- If media contains hard particles, installation of a filter is recommended.
- Rubber seats are not compatible with strong oxidizers, such as concentrated sulfuric acid; select suitable materials for aggressive media.
Optional Custom Configurations:
- Choose alternative seat materials, such as PTFE, for heightened temperature resistance.
- Opt for extended stems to accommodate insulated pipelines or specialized setups.
- Incorporate locking devices to prevent unintended operation.
