Product Description

Product Description

A "Single-Acting Spring Return Pneumatic Actuated UPVC High Platform Wafer Butterfly Valve" is a sophisticated valve assembly designed for precise control and automation of fluid flow in various industrial environments. Here's a detailed breakdown of its components, features, and applications:

1. Single-Acting Spring Return Pneumatic Actuator:

   • Single-Acting: This type of pneumatic actuator uses compressed air to move the valve in one direction (typically to open it), and a spring mechanism is employed to return the valve to its closed position when air pressure is released. This setup is especially useful in applications where fail-safe operation is necessary, ensuring the valve closes automatically in case of air supply failure.
   • Spring Return: The spring return mechanism provides reliable closing force, essential for safety and operational consistency, particularly in systems where maintaining a default state (typically "closed") is critical during power or operational failures.

2. UPVC Material:

   • UPVC (Unplasticized Polyvinyl Chloride): UPVC is a type of hard, chemical-resistant plastic used extensively in fluid handling systems due to its corrosion resistance, chemical stability, and low cost. UPVC is also lightweight compared to metal valves, reducing overall system weight and easing installation.
   • Material Advantages: Suitable for less aggressive and non-high temperature applications, UPVC is commonly used in water treatment, chemical processing industries where corrosive fluids or environments would degrade metal valves more rapidly.

3. High Platform Wafer Butterfly Valve:

   • High Platform: This design feature indicates that the valve is configured to accommodate the actuator on a raised platform, providing more space for the actuator mechanism and facilitating easier access and maintenance. High platform designs are advantageous for integrating larger actuators or when additional clearance is needed for operational components.
   • Wafer Style: The wafer butterfly valve design is named for its thin, disk-like profile, which fits snugly between two pipe flanges. This type of valve is known for its compact design and ease of installation, as it does not require long bolts or a significant amount of space along the pipe run. Wafer valves are effective for systems where quick disassembly and maintenance are valued.

4. Applications:

   • Water Treatment: Due to its corrosion resistance and chemical stability, UPVC is ideal for water treatment applications, including filtration and chemical dosing systems.
   • Chemical Processing: UPVC valves can handle a variety of mild chemicals and are often used in electroplating, acid baths, and similar processes where metal valves would suffer from rapid corrosion.
   • HVAC Systems: In heating, ventilation, and air conditioning systems, UPVC valves provide reliable airflow and fluid control at a lower cost with adequate durability.

5. Advantages:

   • Safety and Reliability: The single-acting spring return ensures that the valve will close in the event of a loss of air pressure, enhancing safety.
   • Cost-Effectiveness: UPVC is generally less expensive than metal alternatives and requires less structural support due to its lightweight nature.
   • Chemical Resistance: UPVC offers excellent resistance to many corrosive substances, reducing maintenance needs and prolonging valve life.

In conclusion, the "Single-Acting Spring Return Pneumatic Actuated UPVC High Platform Wafer Butterfly Valve" is an effective solution for controlling fluid flow in systems where chemical resistance, cost, and safety are priorities. Its design and material composition make it a versatile choice for a variety of industrial applications, especially where corrosive environments or chemicals are involved.
