Structure & Working Principle
Innovative Design Features:
Lift-type Design: The disc moves gracefully along the vertical centerline within the valve body, making it ideal for seamless vertical installations.
Spring-assisted Sealing: Engineered for swift and precise response to pressure changes, ensuring reliability in every scenario. Select models feature reinforced springs for optimal performance in horizontal pipelines.
Operation:
Closed by Default: The valve remains securely shut under no-flow conditions, safeguarding your system.
Efficient Forward Flow: The inlet pressure effortlessly overcomes the spring force, gracefully lifting the disc to permit flow.
Prevention of Reverse Flow: The combination of spring and backpressure effectively forces the disc to close, providing a robust defense against backflow.
