Product Description

Functional Parameters

1. Size Range:
   These valves are available in a wide range of sizes, typically from 1 inch to 24 inches (DN25–DN600), allowing them to be used in various pipeline configurations.

2. Pressure Rating:
   They can withstand pressure ratings from 150 to 600 psi (pounds per square inch), or Class 150–Class 600 in the American standard system. This makes them suitable for both low-pressure and high-pressure applications.

3. Temperature Range:
   The valves can operate within a temperature range of -20°F to 450°F (-29°C to 232°C), enabling them to function effectively in various environmental conditions.

4. Flow Direction:
   These valves are designed for unidirectional flow. When fluid flows in the correct direction, the disc swings open, creating a relatively unrestricted flow path. When the flow reverses, the disc swings back onto the seat, preventing backflow.

Application Areas

1. Oil and Gas Industry:
   In oil and gas pipelines, these valves prevent the reverse flow of oil, gas, and other petroleum products. They are crucial for maintaining pipeline integrity and ensuring the safe transportation of these valuable resources.

2. Chemical Processing:
   Chemical plants often handle corrosive and hazardous fluids. The corrosion-resistant stainless steel components of these valves make them ideal for chemical pipelines, where they prevent backflow and protect equipment from damage.

3. Water Treatment Plants:
   In water treatment facilities, these valves control water flow and prevent backflow, which is essential for maintaining proper treatment processes and ensuring the quality of treated water.

4. Power Generation:
   Whether in a thermal, nuclear, or hydroelectric power plant, these valves play a vital role in pipeline systems. They help regulate the flow of water, steam, and other working fluids, ensuring the safe and efficient operation of power generation equipment.
