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.

In production and life, the emergence of valves is that the utilization rate of their valves and accessories is getting higher and higher, such as check valves, check valves, electric butterfly valves, pneumatic butterfly valves, rubber soft joints, electric ball valves, one-way valves, and wafer butterfly valves. , filter, etc., which have brought great convenience to production and life.
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.
Gate valve is a kind of cut-off valve, which is used to connect or cut off the medium in the pipeline. Gate valve's opening and closing member gate, driven by the valve stem, extend the seat to do linear lifting movement.Advantages of the gate valve.1. low fluid resistanceBecause the valve body of the gate valve internal media channel is straight, the media flow through the gate valve does not change its flow direction, so the fluid resistance is small.2.
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.
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: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.
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.
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.
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.
Test valve refers to the hole and remaining elements of the circular disc and with the aid of its own weight and media stress generated motion to block the media float lower back valve.  automatic valve elegance, additionally referred to as test valve, one-way valve, backflow valve or isolation valve.  disc movement is split into lifting and swing.  elevate test valves are comparable in creation to globe valves besides for the stem that drives the disc.  the medium flows in from the inlet quit (decrease side) and flows out from the hole give up (higher aspect).  valve
