The development trend of electric butterfly valve

Electric butterfly valve means that the butterfly valve is equipped with an electric actuator, which controls the opening and closing of the valve through the electric energy provided by the power supply, so as to realize remote centralized control and automatic operation. Electric butterfly valve can be divided into flange type and disc type according to the connection method, which is an important execution unit in the field of industrial automation control.

What Is The Advantage for Butterfly Valve

Butterfly Valve is a simple structure control valve,it can be used for switching control of low pressure pipeline medium. Our Butterfly Valve is a kind of valve that the disc rotate around the valve shafts to open and close. Features:1, opening and closing convenient and rapid, labor saving, fluid resistance is small, can often operate.2, simple structure, small size, short structure length, small volume, light weight, suitable for large diameter valve.3, can transport mud, the least liquid in the pipe mouth.4.

Background of Butterfly Valve

Butterfly valve is a type of valve that uses a spherical butterfly plate as the opening and last component and turns with the valve stem to open, close and alter the fluid channel. the butterfly plate of the butterfly valve is set up in the diameter route of the pipe. in the cylindrical channel of the butterfly valve frame, the disc formed butterfly plate rotates around the axis of the valve stem at an perspective among 0 ° and 0 °. whilst the butterfly plate is at 0 °, the valve is closed, and when the butterfly plate is at ninety °, the valve is absolutely opened.

Advantages and Disadvantages of Butterfly Valve

Advantage 1. The opening and closing is convenient, quick, labor-saving, low in fluid resistance, and can be operated frequently.2. Simple structure, small overall size, short structural length, small volume and light weight, which is suitable for large-diameter valves.3. Mud can be transported, and the liquid accumulated at the pipe mouth is the least.4. Under low pressure, good sealing can be achieved.5. Good adjustment performance. 6. When fully opened, the effective circulation area of the valve seat channel is large, and the fluid resistance is small.7.

Advantages Of Two Shaft Wafer Type Butterfly Valve

Advantages:1. easy and quick to start and close, labor-saving, low fluid resistance, can be operated frequently2. Simple structure, small size, short structure length, small volume, light weight3. start and close torque is small, because the butterfly plate on both sides of the shaft is basically equal to the action of the medium, and the direction of the torque generated is opposite, so it is relatively labor-saving4. The material of sealing surface generally adopts rubber, plastic, so the low pressure sealing performance is good.5.

Introduction of Butterfly Valve Characteristics

1. Butterfly valve has the characteristics of simple structure, small volume, light weight, low material consumption, small installation size, quick switch, 90 reciprocating rotation and small driving torque, etc. It is used to cut off, connect and adjust the medium in the pipeline, and has good fluid control characteristics and closing and sealing performance.2. Butterfly valves can transport mud, and the liquid accumulated at the pipe mouth is the least. Under low pressure, good sealing can be achieved. Good adjustment performance.3.

The Difference Between Butterfly Valve With a pin and Without Pin

FIRST:The difference between butterfly valve has a pin and without pin: Price: the without pin butterfly valve is more expensive than the pin ones. Usage: WITHOUT PIN TYPE REDUCE THE RISK OF LEAKAGE.

Pressure Test Method Of Check Valve

Check valve is a valve that relies on the medium itself to flow and automatically open and close the valve flap, used to prevent the backflow of the medium, also known as check valve, check valve, backflow valve, and back pressure valve.

The Differences Between Soft Seal Butterfly Valve And Hard Sear

Hard seal butterfly valve is called "hard seal" when both sides of the seal are made of metal or other hard materials. The sealing function of this kind of seal is poor, but it is resistant to high temperature, wear and tear, and has good mechanical function.
