Soft sealing butterfly valve, also known as resilient seated butterfly valves, offer numerous benefits in various industries. Here are the key advantages of using soft sealing butterfly valves:
Excellent Sealing Capability:
Soft sealing butterfly valves feature a resilient seat made of materials such as EPDM, NBR, or PTFE. These materials provide excellent sealing properties, ensuring tight shut-off and preventing leakage across the valve seat. The soft seat conforms to the disc, creating a reliable seal even at low pressures and in moderate vacuum conditions.
Bubble-Tight Shut-Off:
Soft sealing butterfly valves are known for their bubble-tight shut-off capability. The resilient seat material forms a tight seal against the disc, preventing any leakage or seepage of the fluid being controlled. This feature is especially crucial in applications where leakage prevention is critical, such as water treatment, chemical processing, and food and beverage industries.
Low Operating Torque:
Soft sealing butterfly valves require relatively low operating torque compared to other valve types. The resilient seat design and reduced friction between the seat and disc result in smoother operation and reduced energy consumption during valve actuation. This low torque requirement makes soft sealing butterfly valves suitable for both manual and automated operation, contributing to energy efficiency.
Bi-Directional Flow Capability:
Soft sealing butterfly valves offer bi-directional flow capability, allowing the fluid to flow in either direction without compromising the sealing performance. This feature eliminates the need for specific valve orientation during installation and simplifies piping design.
Wide Range of Applications:
Soft sealing butterfly valves find applications in various industries due to their versatility. They are suitable for handling a wide range of fluids, including water, air, gases, chemicals, slurries, and even abrasive media. This versatility makes them popular in industries such as water and wastewater treatment, HVAC, power generation, chemical processing, and food and beverage production.
Easy Maintenance:
Soft sealing butterfly valves are relatively easy to maintain. The resilient seat is replaceable, allowing for quick and cost-effective repairs or seat replacement when necessary. Routine maintenance typically involves inspecting and cleaning the seat and disc to ensure optimal performance. This ease of maintenance contributes to reduced downtime and lower overall maintenance costs.
Cost-Effective Solution:
Soft sealing butterfly valves are often more cost-effective than other types of valves, such as gate valves or ball valves. Their simplified design, reduced component count, and ease of installation contribute to lower initial costs. Additionally, their low torque requirements and energy-efficient operation result in reduced operational costs over the valve’s lifespan.
Lightweight and Compact Design:
Soft sealing butterfly valves have a lightweight and compact design. This feature makes them easier to handle during installation and requires less space in piping systems. Their compact size also contributes to lower material and transportation costs.
Overall, the benefits of using soft sealing butterfly valves in various industries include excellent sealing capability, bubble-tight shut-off, low operating torque, bi-directional flow capability, wide application range, easy maintenance, and cost-effectiveness. These advantages make soft sealing butterfly valves a reliable and efficient choice for flow control applications across different sectors.
