High quality High-performance soft seal butterfly valve is offered by China manufacturer Milestone. When selecting a butterfly valve for your application, one of the key considerations you must make is whether to choose a soft seal or a hard seal butterfly valve. Both have unique advantages and limitations, making it essential to understand the differences between them before making a decision.
Soft seal butterfly valves, also known as resilient-seated butterfly valves, rely on flexible materials like elastomers and rubber to create a tight seal between the valve disc and the body. These valves are ideal for applications that require tight shutoff and low torque operation.
