Product Description
The pneumatic double gate valve adopts a double-sided hard seal structure. When the air source is introduced from the upper intake port, the valve stem drives the valve plate to move downward and the valve closes. When the gas source is introduced from the lower air inlet, the valve stem drives the valve plate to move upward, and the valve opens. Solved the sealing problem of the upstream and downstream pressure of the ash conveying pipeline, as well as the corrosion and wear resistance of the sealing components and the ash problem on the sealing area. This greatly extends the service life of the valve, and under normal circumstances, the service life of vulnerable parts of the valve can reach more than two years.
Pneumatic double plug valves are mainly used in the fly ash pneumatic conveying system of thermal power generation enterprises, as discharge valves, balance valves, exhaust valves, and blockage valves for bin pumps. They can also be used as pipeline switching valves and ash unloading valves for ash storage. Dry dust, water and other media with wear and tear in mining, papermaking, chemical industry, etc. are used for opening and closing pipelines.
It can be widely used in key areas such as feeding, discharging, exhaust, pipeline branching, and pipeline switching. Pneumatic double gate valve is a main control equipment for the flow or conveying volume of powder, crystalline granules, granular materials, and small pieces of materials. It is widely used in industries such as metallurgy, mining, building materials, grain, and chemical industry to control flow changes or quickly cut off.

Our Advantages
Advantage
High degree of automation: closely coordinated with pneumatic control systems, it can easily achieve remote control and automation operations, and can be integrated into automated production lines to reduce manual intervention, improve production efficiency and control accuracy.
Energy saving and efficient: Compared to other types of valves, pneumatic gate valves have lower energy consumption and are more energy-efficient and environmentally friendly. Its fast switching feature also helps reduce energy waste in situations where frequent flow adjustment is required.
Flexible installation: compact structure, light weight, installation not limited by angle, suitable installation position and method can be selected according to actual needs, convenient for installation and use in various complex industrial environments.
Low maintenance cost: Due to its simple structure, high reliability, and long service life of its main components, the maintenance frequency is low and the maintenance cost is relatively low. Meanwhile, the replacement of its vulnerable parts is also relatively convenient.
Safe and reliable: It can form a reliable seal in the closed state, effectively preventing medium leakage and avoiding safety accidents and environmental pollution that may be caused by medium leakage. In addition, pneumatic drive methods have inherent safety in some hazardous areas and can avoid hazardous factors such as electrical sparks.
Product Features
Simple structure: mainly composed of valve body, gate plate, cylinder and other components, with a simple structure that is easy to understand and maintain, reducing the probability of failure and lowering maintenance costs and difficulties.
Easy to operate: Driven by pneumatic actuators, it can directly receive electrical/pneumatic signals, achieve remote control and automated operation, easy to operate, can quickly respond to control instructions, and improve work efficiency.
Fast switching: The pneumatic drive mode enables the gate valve to complete the switching action in a short time, with a fast response speed, which can meet some process requirements that require frequent start stop or rapid flow adjustment.
Good sealing performance: Using soft or hard sealing materials such as rubber, polytetrafluoroethylene, ceramics, etc., the sealing performance is superior, which can effectively prevent medium leakage, reduce energy loss and environmental pollution.
High reliability: Pneumatic actuators have overload protection function, which can automatically shut down in case of abnormal situations, ensuring the safe operation of the equipment. At the same time, the key components of the valve have been precisely designed and rigorously tested, resulting in high stability and durability.
Wide adaptability: It can be applied to the control and regulation of various industrial media, such as water, steam, oil, gas, powder, crystalline particles, granular materials, and small pieces of materials, etc. It can work normally under different temperature and pressure conditions.
