Summary:
Soft seal gate valves are commonly used in conjunction with hydraulic systems. These valves are widely found in water treatment plants, sewage systems, and other industrial applications. The materials typically used include cast iron, ductile iron, and cast steel. They are usually equipped with flanged connections. However, they are generally available in two types: bright rod and dark rod. This distinction is important for customers to note. One of the key features of these valves is their sealing performance, which plays a significant role in their functionality and application.
Soft Seal Gate Valve Specification Manual:
1. The operating end of the soft seal gate valve should be square-shaped and standardized, positioned facing downward so that operators can easily access and control it from the ground level. Valves with exposed discs are not recommended for underground piping systems.
2. If the soft seal gate valve is installed deep underground, and the distance between the operating mechanism and the display panel from the ground is greater than or equal to 1.5 meters, an extension rod must be provided and securely fastened. This allows personnel to observe and operate the valve from the surface. In short, underground operations are not ideal for opening and closing valves within a pipeline network.
3. Since pneumatic valves in the system are often manually operated, the number of rotations required for opening and closing should be limited. Even for large-diameter valves, the rotation count should stay within 200 to 600 revolutions.
4. To ensure ease of operation, the maximum torque required to open or close the valve under pipeline pressure should not exceed 240 N·m.
5. The direction of operation for the soft seal gate valve should follow a clockwise motion when closing.
Evaluation of a Vertical Valve: The appearance of a soft-seal gate valve is typically well-crafted, often painted in a standard blue color. Compared to other types of valves, it offers a more cost-effective solution and is considered part of the general valve series. Its design and affordability make it a popular choice in many industrial settings.
