Whether for new installations or replacements, the D71J Manual Handle Rubber Lined Butterfly Valve offers a durable, cost-effective solution that ensures efficient operation and long-lasting performance. Features
- Rubber Lined Construction: The valve body is lined with high-quality rubber (EPDM, NBR), ensuring excellent corrosion resistance and tight sealing for a wide range of applications.
- Manual Handle Operation: Equipped with a manual handle for simple and direct operation, ideal for low to medium pressure systems where automation is not required.
- Durability and Strength: Built with cast iron, carbon steel, or stainless steel (CF8/CF8M), ensuring a long service life in harsh environments.
- Versatile Sealing: The rubber lining provides excellent sealing performance, especially for applications involving chemicals, water, and air, preventing leakage even under challenging conditions.
- Cost-Effective: The manual operation and rubber-lined design make this valve an affordable solution for a variety of industries, offering reliable performance without the high costs associated with other valve types.
- Wide Temperature Range: Suitable for use in temperatures from -10°C to 80°C (14°F to 176°F), making it ideal for many industrial fluid control applications.
- Compact and Lightweight: The wafer-style design minimizes space requirements, making it suitable for installations with limited space or in existing pipe networks.
- Easy Installation: The wafer connection allows the valve to be easily installed between flanges, reducing installation time and costs.
