Product Description

1.The Structural Diagram
2. Applications and Performance Features
Specifically engineered for high-rise building water supply and drainage systems as well as fire pipeline water supplies, the Huhang Forged Steel Butterfly Check Valve offers unparalleled protection against the destructive water hammer effect caused by backflow. Its robust design ensures the safeguarding of pumps and pipeline equipment. The valve's standout performance features include:

1) This versatile valve can be installed either vertically or horizontally. With a disc that moves with remarkable flexibility, it operates seamlessly with minimal noise, ensuring not only safety but also reducing the likelihood of faults, thereby enhancing reliability.

2) It boasts an intelligently designed structure with exceptional sealing capabilities, guaranteeing superior performance and reliability in various applications.

3) Recognized for its wear-resistant qualities, this valve promises a prolonged service life, delivering consistent performance year after year.

3. Operating Principle
Crafted with precision, the silent check valve comprises a well-engineered assembly of a valve body, disc, spring, outlet, and cap. Its sophisticated operating principle is illustrated as follows:
When idle, the valve disc remains securely closed, thanks to the spring's pre-tension force, ensuring no unwanted flow occurs.
Upon the presence of media flow, the pressure exerted by the media effortlessly overcomes the spring's pre-tension force, prompting the valve disc to open. Conversely, in instances of reverse flow, the combined force of the backflowing media and the spring's pre-tension swiftly closes the valve disc, effectively blocking any backflow.
