Wafer Connection Description
The Wafer Butterfly Valve uses a wafer-style connection with several advantages:
– Design: Fits between two flanges in a piping system. It has a compact and lightweight design.
– Installation: Mounted between flanges using bolts. Easy to install and remove without disturbing the pipeline.
– Advantages:
– Space Efficiency: Saves space compared to flanged valves.
– Cost-Effective: Generally less expensive due to reduced material and labor costs.
– Easy Maintenance: Simplifies maintenance and replacement. Can be easily removed and reinstalled.
– Leakage Prevention: Provides a reliable seal between the valve and flanges. Reduces the risk of leakage.
Soft-Seal and Hard-Seal Options
The Electric Wafer Butterfly Valve offers both soft-seal and hard-seal options:
– Soft-Seal:
– Description: Uses elastomeric materials (e.g., EPDM, NBR) for sealing. Provides a tight seal for lower pressures and temperatures.
– Applications: Commonly used in water treatment, HVAC systems, and low-pressure applications.
– Hard-Seal:
– Description: Uses metal or ceramic materials for sealing. Offers higher durability and resistance to high temperatures and pressures.
– Applications: Suitable for demanding applications in petrochemical, power generation, and high-temperature processes.
Media and Working Conditions
- Media
– Water: Suitable for various water applications, including potable and non-potable water systems.
– Air: Effective for air and gas applications in HVAC and industrial processes.
– Chemicals: Can handle certain chemicals depending on the seal material and construction.
- Working Conditions
– Operating Temperature: Typically operates from -20°C to +120°C, depending on seal material.
– Operating Pressure: Suitable for medium to low-pressure applications. Pressure ratings vary by valve size and construction.
– Environmental Conditions: Designed for standard and slightly harsh conditions.
Summary
The Electric Wafer Butterfly Valve offers reliable performance with a compact design. It integrates electric actuators in regulating, explosion-proof, and intelligent types. The valve comes in both soft-seal and hard-seal configurations to suit different needs. Its space-efficient and cost-effective design makes it ideal for various media and working conditions, enhancing control and automation in industrial settings.
