Good sealing performance: Adopting an inflatable sealing ring, when the valve is closed, the rubber sealing ring inflates and expands, tightly pressing against the spherical dome valve core to form a reliable sealing ring, which can effectively cut off the flow of materials in the pipeline and withstand a certain pressure difference.

Fully enclosed drive: The pneumatic actuator is a fully enclosed rotary push rod cylinder, linear cylinder, sector cylinder, etc., which directly drives the dome valve to rotate, effectively preventing dust from entering and causing wear, leakage, and other phenomena.

High quality materials: The valve core is made of different materials and hardened according to the usage situation, with a smooth and hard surface, which can ensure good contact with the rubber sealing ring; The sealing ring is made of special rubber and has the characteristics of high temperature resistance, corrosion resistance, wear resistance, and aging resistance.

Good liquidity: When the valve is opened, the material port flows smoothly without obstruction, avoiding direct flushing of the material onto the valve core.

Function

Truncation function: It can quickly and reliably cut off the material or fluid flow in the pipeline, whether it is gas, liquid, semi fluid, solid powder or other substances, it can be effectively cut off when needed, ensuring the normal operation and safety of the system.

Flow regulation: In some cases, the flow area of the medium can be changed by adjusting the position of the valve core, thereby achieving a certain degree of regulation of the flow rate. However, the accuracy of flow regulation is usually relatively low, mainly relying on the cutoff function.

Purpose

Electric power industry: widely used in ash and slag systems of power plants, such as feeding and discharging ports, exhaust ports, blowing ports, blocking ports, and switch controls for pipeline switching of dry ash and dry powder materials.

Metallurgical industry: Used for conveying and controlling powdered materials in metallurgical processes, such as ore powder, coal powder, etc., as well as for cutting off and controlling flow in the feeding and discharging processes of some metallurgical furnaces.

Chemical industry: Suitable for conveying pipelines of chemical raw materials and products, such as plastic particles, chemical powders, liquid chemical raw materials, etc. The switch control in the conveying system can ensure accurate distribution and safe transportation of materials in the chemical production process.

Food industry: In the process of food processing, it is used for conveying and distributing powdered materials such as flour, sugar powder, starch, as well as controlling the conveying pipelines of some food additives to ensure the hygiene and safety of food production.

Pharmaceutical industry: It can be used as a transportation pipeline for powdered drug raw materials, intermediates, and finished products in pharmaceutical processes, such as controlling the feed and discharge ports of capsule filling machines, tablet presses, and other equipment to ensure the quality and accuracy of drug production.

Advantage

High reliability: The structure is simple, the design is reasonable, and the key components are made of high-quality materials and advanced technology, which has high reliability and stability, and can operate stably for a long time under harsh working conditions.

High degree of automation: closely coordinated with pneumatic control systems, it can achieve remote control and automated operation, easily integrated into automated production lines, reducing manual intervention and improving production efficiency and control accuracy.

Low maintenance cost: Due to non-contact opening and closing and good sealing performance, the risk of wear and leakage is reduced, and the frequency and cost of maintenance are lowered. Meanwhile, its main vulnerable parts are the sealing ring and valve core, which are relatively easy to replace.

Wide adaptability: It can adapt to various media and working conditions, work normally within a wide temperature and pressure range, and is suitable for various industrial fields and process flows, with strong universality and adaptability.

Good safety: It can form a reliable seal in the closed state, effectively preventing material leakage, avoiding safety accidents and environmental pollution that may be caused by material leakage, and ensuring the safety and environmental friendliness of the production process.
