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.

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.

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.

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.

The Difference Between Ball Valve and Butterfly Valve

1. Butterfly valve is composed of valve body, valve seat, valve plate and valve stem, and all fittings are exposed and can be seen at a glance; Ball valve is composed of valve body, valve core (a round ball) and valve stem. The position of valve core is inside the valve body, and only part of it can be seen by naked eyes, so the sealing performance of ball valve is better than that of butterfly valve.2. Butterfly valves are relatively simple in structure, and butterfly valves with low pressure are generally used. The zui high pressure of butterfly valves can only reach 64kg.

Difference Between Butterfly Valve and Gate Valve

Different principlesButterfly valve, also known as flap valve, is a kind of regulating valve with simple structure. It can also be used for on-off control of low-pressure pipeline media, and it mainly plays the role of cutting off and throttling. When the butterfly valve is fully opened to fully closed, it is usually less than 90. The butterfly valve and the butterfly rod have no self-locking ability. In order to position the butterfly plate, a worm gear reducer should be installed on the valve stem.
