Stainless Steel Butterfly Valve Part

Stainless Steel Butterfly Valve Part

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.

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.

Valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metals, and radioactive media. Mainly cut and throttle on the pipeline. The butterfly valve opening and closing member is a disc-shaped butterfly plate that rotates around its own axis in the valve body to achieve the purpose of opening and closing or adjusting.


Characteristics

1. Butterfly valve has the characteristics of simple structure, small volume, light weight, low material consumption, small installation size, rapid switch, 90° reciprocating rotation and small driving torque. It is used to cut off, connect and adjust the medium in the pipeline. Has good fluid control characteristics and closes sealing performance.

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

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

The driving form includes manual, worm gear, electric, pneumatic, hydraulic, electro-hydraulic linkage and other actuators, which can realize remote control and automatic operation.


Advantage

1. Simple structure, small size, short structure length, small size, light weight, suitable for large diameter valves.

2. Under low pressure, can achieve a good seal.

3. The valve seat channel has a large effective flow area and a small fluid resistance when fully opened.

4. The sealing surface material is generally made of rubber and plastic, so the low-pressure sealing performance is good.

5. Flexible and labor-saving operation, manual, electric, pneumatic and hydraulic modes are available.
