Product Characteristics

1. API Butterfly Valve has the characteristics of simple structure, small size, light weight, low material consumption, small installation size, quick switch, 90° reciprocating rotation and small driving torque. It is used for cutting, connecting and adjusting the pipeline. Medium with good fluid control and closed sealing properties.

2. The API Butterfly Valve can transport the mud and accumulate the least amount of liquid at the pipe mouth. A good seal can be achieved at low pressure. The adjustment performance is good.

3, the streamlined design of the butterfly plate, the fluid resistance loss is small, can be described as an energy-saving product.

4. The valve stem is a through-rod structure. After quenching and tempering treatment, it has good comprehensive mechanical properties, corrosion resistance and scratch resistance. When the butterfly valve is opened and closed, the valve stem only rotates and does not perform lifting operation. The packing of the valve stem is not easy to be broken and the sealing is reliable. It is fixed with the cone pin of the butterfly plate, and the overhanging end is designed to prevent the punch-out type, so as to prevent the valve stem from collapsing when the valve stem and the butterfly plate are accidentally broken.

5. Connection methods include flange connection, clamp connection, butt weld connection and lug-to-clip connection.


The hydraulic test shall be carried out in accordance with the standards:

- Shell strength test, applying pressure 1.5 times as design pressure

- High pressure hydraulic seal test, applying 1.1 times design pressure

- Low pressure air test, applying a pressure of 0.6 MPa.

Taking the 300LB valve as an example, the pressure rate is as follows:

*Shell strength test, 7.5Mpa;

* High pressure water seal test, 5.5Mpa;

* Low pressure air test, 0.6Mpa.

Due to the wide application of our products and our favorable market position, we strive to sell our Flanged Type Manual Operator API 609 Standard Butterfly Valve to more countries and bring our high-quality products and services to every corner of the world. We have a complete quality feedback system to ensure that the quality of our products reaches the zero-defect standard, and we will also provide customers with complete and thoughtful services.
