Product Overview
Introducing the D71X Stainless Steel Wafer Butterfly Valve, a marvel of engineering precision, designed for swift opening and closing with exceptional flow regulation capabilities. Its compact, robust structure ensures unrivaled sealing reliability, making it the go-to solution across industries such as water treatment, chemical processing, food production, pharmaceuticals, and more. Perfectly suited for environments dealing with corrosive media or those demanding high purity, this valve is your answer to industry-specific challenges.
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
- Body/Disc/Stem: Crafted from premium stainless steel (304, 316, or 316L), offering superior resistance to corrosion.
- Seat Ring: Made from rubber materials, with EPDM as the default choice, supporting temperatures from -20°C to 120°C. Optional alternatives like NBR and Fluorocarbon are available for specialized media needs.
- Actuation: Choose from manual options (lever or gear-operated) or opt for customized pneumatic/electric actuators for tailored automation.
Working Principle
Experience seamless fluid control as the valve disc rotates a full 90° via the stem. The centric design guarantees even contact between the disc and seat, facilitating bidirectional sealing with negligible leakage, even under low pressure.
Key Feature
- Corrosion Resistance: A combination of stainless steel and rubber sealing, built for durability in acidic and alkaline settings.
- Low Flow Resistance: Its full-bore design ensures minimal pressure drop, optimizing flow efficiency.
- Lightweight & Durable: This compact valve is a third the weight of standard gate valves, promising longevity and low maintenance.
- Rapid Operation: Achieve swift manual or automated control with a simple 90° disc rotation.
- Temperature Range: Operates seamlessly between -20°C and 180°C, depending on seat material used.
Applications
- Water Treatment: Essential for systems involving water supply, drainage, firefighting, and wastewater management.
- Industrial Piping: Perfect for applications in chemical processing, petroleum, gas distribution, and HVAC systems.
- Food & Pharma: Available in sanitary-grade options with polished surfaces, aligning with GMP standards.
Installation & Maintenance
- Installation: Ensure compatibility with matching flanges and symmetrically tighten bolts to protect the seat integrity.
- Maintenance: Regularly check seat wear and stem lubrication; replace seals every 3-5 years based on service conditions.
Precautions
- Protect against overpressure or excessive temperature to maintain seal integrity.
- Install a filter if the media contains abrasive particles to avoid potential damage.
- Rubber seats are incompatible with strong oxidizers like concentrated sulfuric acid; choose suitable materials for aggressive media.
Optional Configurations:
- Select alternative seat materials, such as PTFE, for enhanced high-temperature resistance.
- Opt for an extended stem to accommodate insulated pipelines or unique installation requirements.
- Integrate locking devices to prevent unintended operation, enhancing safety and control.
