Product Overview
Introducing the D71X Stainless Steel Wafer Butterfly Valve, a masterstroke of engineering that combines a centric design with wafer-type connections for swift operation and precise flow control. With its compact, reliable sealing structure, this valve is the epitome of versatility, perfect for a myriad of applications including water treatment, chemical processing, food production, and pharmaceuticals. Especially designed to handle corrosive or high-purity media, it stands as a testament to durability and innovation.
Model Breakdown
- D: Butterfly Valve
- 7: Wafer Connection
- 1: Centric Design (Valve Disc Rotates on Central Axis)
- X: Rubber Seat Material (e.g., EPDM, NBR, etc.)
Structure & Materials
- The core construction features high-quality stainless steel (304, 316, or 316L), ensuring unmatched corrosion resistance, strength, and longevity.
- Seat Ring: Crafted from premium rubber (standard EPDM, temp range: -20°C~120°C; NBR or Fluorocarbon options available for specific needs).
- Actuation: Choose manual (lever or gear) or opt for tailored pneumatic/electric actuation solutions to fit your requirements.
Working Principle
The valve's operation is a marvel of simplicity and efficiency: a 90° rotation of the disc via the stem regulates fluid flow. The centric design guarantees even disc-seat contact, achieving bidirectional sealing with utmost precision, ensuring minimal leakage even under low-pressure conditions.
Key Feature
- Corrosion Resistance: The perfect blend of stainless steel and rubber sealing, designed for challenging acidic or alkaline environments.
- Low Flow Resistance: Its full-bore design ensures pressure loss is virtually eliminated, optimizing system efficiency.
- Lightweight & Durable: With a compact build, it weighs only a third of traditional gate valves, reducing maintenance overhead.
- Rapid Operation: Achieve quick manual or automated flow control with an effortless 90° rotation.
- Temperature Range: -20°C~180°C, adaptable based on seat material selected for specific applications.
Applications
- Water Treatment: Ideal for water supply, drainage, firefighting, and wastewater management systems.
- Industrial Piping: A versatile choice for chemical, petroleum, gas, and HVAC systems.
- Food & Pharma: Sanitary-grade options available with polished surfaces, complying with GMP standards.
Installation & Maintenance
- Installation: Ensure compatibility with matching flanges; symmetrically tighten bolts to preserve seat integrity.
- Maintenance: Conduct regular inspections of seat wear and stem lubrication, replacing seals every 3-5 years based on operational conditions.
Precautions
- Prevent seal failure by avoiding overpressure or excessive temperatures.
- Install filters to protect against hard particle intrusion in the medium.
- Rubber seats should not be used with strong oxidizers like concentrated sulfuric acid. Choose suitable materials for aggressive media environments.
Optional Configurations:
- Select alternative seat materials, such as PTFE, for enhanced high-temperature resistance.
- Opt for an extended stem design for insulated pipeline applications or unique installation scenarios.
- Incorporate locking devices to prevent unintended valve operation.
