Check Valve Wafer Lug Type Product Introduction
Product Overview:
The Check Valve Wafer Lug Type is a compact, efficient valve designed to prevent backflow in pipeline systems. This valve features a wafer lug design that allows it to be installed between flanges with the aid of lugs on the valve body. It is commonly used in various industrial applications to ensure the one-way flow of media and protect systems from potential damage caused by reverse flow.
Features:
- Wafer Lug Design: The valve is equipped with lugs that allow for easy installation between flanges. This design simplifies the installation process and reduces the need for additional components.
- Compact and Lightweight: The wafer lug design is slim and lightweight, making it ideal for installations where space is limited and reducing the overall weight of the system.
- Reliable Backflow Prevention: The valve effectively prevents backflow by using a spring-loaded or gravity-operated disc that closes automatically when flow stops or reverses.
- Low Pressure Drop: The streamlined design minimizes flow resistance, resulting in a low-pressure drop across the valve and ensuring efficient system operation.
- Durable Construction: Made from high-quality materials such as cast iron, stainless steel, or alloy steel, the valve is built to withstand various operating conditions and provide long-lasting performance.
Advantages of Wafer Lug Design:
- Easy Installation: The wafer lug design allows the valve to be easily installed between flanges without the need for additional gaskets or sealing rings, simplifying the installation process.
- Space Efficiency: The compact design saves space and reduces the overall footprint of the pipeline system, making it suitable for tight or congested installations.
- Cost-Effective: The wafer lug check valve typically has a lower initial cost and reduced installation expenses compared to traditional flanged valves.
- Reduced Weight: The lightweight design makes handling and installation easier, reducing labor costs and installation time.
Product Structure:
- Valve Body: Constructed from durable materials such as cast iron, stainless steel, or alloy steel. The wafer lug body features lugs that allow for secure mounting between flanges.
- Disc: The disc swings open and closed based on the direction of flow. It is designed to provide a tight seal and prevent backflow effectively.
- Hinge Pin: Connects the disc to the valve body, allowing smooth operation of the disc and ensuring reliable performance.
- Sealing Surface: Precision-machined to ensure a tight seal and minimize leakage, contributing to the valve’s effectiveness in preventing backflow.
- Retaining Lug: Keeps the valve securely in place between flanges and ensures proper alignment during operation.
Design Standards:
– API 6D: Pipeline valve standard, ensuring the valve meets industry requirements for design, materials, and performance.
– ASME B16.34: Standards for valve design and manufacturing, providing guidelines for construction and safety.
– API 598: Standards for valve inspection and testing, ensuring the valve’s reliability and performance.
