Carbon Steel Butterfly Valve Casting

Carbon Steel Butterfly Valve Casting

The butterfly valve, also known as the flap valve, is a simple regulating valve. The butterfly valve that can be used for the switching control of the low-pressure pipeline medium means that the closing member (valve or disc) is a disc that rotates around the valve shaft to achieve opening and closing a kind of valve.

Product Detail:

The butterfly valve, also known as the flap valve, is a simple regulating valve. The butterfly valve that can be used for the switching control of the low-pressure pipeline medium means that the closing member (valve or disc) is a disc that rotates around the valve shaft to achieve opening and closing a kind of valve.

In order to meet the requirements of industrial applications such as high and low temperature, strong erosion and long life, metal sealing butterfly valves have been greatly developed. With the application of high temperature resistance, low temperature resistance, strong corrosion resistance, strong erosion resistance and high strength alloy materials in butterfly valves, metal sealing butterfly valves have been widely used in industrial fields such as high and low temperature, strong erosion and long life. Butterfly valves with large diameter (9~750mm), high pressure (42.0MPa) and wide temperature range (-196~606°C) have emerged, which has brought the butterfly valve technology to a new level.


Characteristics

1. The streamlined design of the butterfly board, so that the fluid resistance loss is small, can be described as an energy-saving product.

2. 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 move up and down. 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.


How does LongZhu do quality control for sand casting?

First, we have an area control system in each production process. Secondly, we are equipped with complete test instruments, such as Y-ray detection device, all-digital intelligent ultrasonic flaw detector, low temperature impact tester, desktop, portable Brinell hardness tester, direct reading spectrometer, fluorescent magnetic particle detector, ultrasonic thickness gauge , universal strength testing machine, molten steel thermocouple thermometer, metallographic microscope, etc.Thirdly, sample will be provided before mass production. Also, for mass production, we will select some products randomly for testing.


Service Flow

1. Help customer to design, making drawing;

2. Providing free samples + dimension inspection report + material report...;

3. Checking raw material, and inform customer before mass production;

4. Informing customer production schedule weekly;

5. Arrange shipment, and Inform customer in advance 7 days before finishing the order.
