Product Overview
Introducing the D71X Stainless Steel Wafer Butterfly Valve, a masterfully crafted, centrically designed butterfly valve featuring wafer-type connections. It offers swift opening and closing with exceptional flow regulation. Its compact yet robust construction ensures reliable sealing, making it indispensable across industries such as water treatment, chemical, food, and pharmaceuticals. Particularly advantageous for handling corrosive media or high-purity applications, it stands as a pillar of efficiency and reliability.
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: Precision-engineered from premium stainless steel options (304, 316, or 316L) offering exceptional corrosion resistance.
- Seat Ring: Composed of high-quality rubber materials, EPDM as standard, accommodating temperatures from -20°C to 120°C. Optional materials like NBR and Fluorocarbon are available for specialized media requirements.
- Actuation: Operable manually via lever or gear, with options for tailored pneumatic or electric actuators to suit unique operational demands.
Working Principle
The innovative valve disc operates with a 90° rotation through the stem, enabling precise control over fluid flow. This centric design ensures consistent contact between the disc and seat, facilitating bidirectional sealing and minimizing leakage even under low-pressure differentials.
Key Feature
- Corrosion Resistance: The combination of stainless steel and rubber sealing provides unparalleled protection in acidic and alkaline environments.
- Low Flow Resistance: Featuring a full-bore design that significantly reduces pressure loss, enhancing system efficiency.
- Lightweight & Durable: Its compact and lightweight design, weighing just a third of comparable gate valves, ensures ease of installation and reduced maintenance needs.
- Rapid Operation: Achieve quick control, whether manual or automated, with a simple 90° rotation.
- Temperature Range: Adaptable from -20°C to 180°C, depending on the seat material utilized.
Applications
- Water Treatment: Essential for water supply, drainage, firefighting, and wastewater systems.
- Industrial Piping: Perfect for chemical, petroleum, gas, and HVAC applications.
- Food & Pharma: Available in sanitary-grade options with polished surfaces, meeting GMP standards.
Installation & Maintenance
- Installation: Ensure compatible flanges are used, and bolts are tightened symmetrically to preserve seat integrity.
- Maintenance: Routine inspection of seat wear and stem lubrication is advised, with seal replacements suggested every 3-5 years based on service conditions.
Precautions
- Prevent overpressure and excessive temperatures to avoid compromising the seal integrity.
- When media contains hard particles, install a filter to protect the valve mechanism.
- Note that rubber seats are unsuitable for strong oxidizers, like concentrated sulfuric acid; choose appropriate materials for aggressive media.
Optional Configurations:
- Alternative seat materials, such as PTFE, are available for enhanced high-temperature resistance.
- Extended stem options cater to insulated pipelines or unique installation needs.
- Locking devices are available to prevent unintentional operation, ensuring safety and control.
