Pneumatic Butterfly Valve

The pneumatic butterfly valve is composed of a pneumatic actuator and a butterfly valve. The pneumatic butterfly valve is a pneumatic valve that uses a circular butterfly plate that rotates with the valve stem to realize the opening and closing. It is used more and more on medium-bore pipes. Pneumatic butterfly valve classification: stainless steel pneumatic butterfly valve, hard seal pneumatic butterfly valve, soft seal pneumatic butterfly valve, carbon steel pneumatic butterfly valve.

China Refrigation Equipment Exhibition

The Chinese Refrigation Equipment Exhibition is the most special exhibition in Refrigation field.Our Diefei Brand Check valve and Butterfly valve is an important part of this Exhibition.We have the expertise and experience to produce,also have a big After-service team . We get the high apprecition from our customers.

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.

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.

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.

Matters Needing Attention in the Use of Gate Valves

1. Handwheel, handle and transmission mechanism are not allowed to be used for lifting, and collision is forbidden. 2. The double gate valve should be installed vertically (i.e. the valve stem is in the vertical position and the handwheel is at the top). 3. The gate valve with bypass valve should be opened before opening (to balance the pressure difference between inlet and outlet and reduce the opening force). 4. Gate valve with transmission mechanism shall be installed according to the product instruction manual. 5.

Features of electric ball valve

The high-pressure pneumatic ball valve only needs to use the pneumatic actuator to rotate the air source by 90 degrees and a small rolling torque to be tightly closed. Completely equal valve body cavity provides medium with low resistance and straight-through flow path. It is generally believed that the ball valve is suitable for direct opening and closing applications, but recent developments have designed the ball valve so that it can be used for throttling and control systems.

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.

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.

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.

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.
