Product Description

Product Description

D373H lug type American standard butterfly valve, also known as lug type butterfly valve or single clip butterfly valve, is connected between two pipeline flanges using double head bolts. The American standard lug butterfly valve is a type of valve that uses a circular butterfly plate as the opening and closing component and rotates with the valve stem to open, close, and regulate the fluid channel. It is suitable for industries such as fire pipelines, drainage, sewage, food, heating, gas, ships, hydropower, metallurgy, energy systems, and light textile.
Product features:
1. Reasonable design, compact structure, easy assembly and disassembly, and easy maintenance.
2. Adopting an eccentric structure to reduce the friction of the sealing ring and extend the service life of the valve.
3. Completely sealed, with zero leakage, suitable for high vacuum conditions.
4. Replacing valve plate sealing rings, butterfly plates, rotating shafts and other materials can be applied to various media and temperatures.
