(1) The takeover standard of the split multi-leaf air volume dispatching valve is the same as the rectangular air duct standard of the national ventilation duct standardization.

(2) The blades of the air volume dispatching valve are side-opening and forward-opening, which are used as dispatching valves in ventilation, air dispatching and air purification systems.

(3) According to the test, the air-tightness of the air volume dispatching valve is good, and its relative air leakage is about 10%, and the dispatching performance is good.

The current manual air valve mold a molding, high strength, good sealing, smooth appearance, low resistance. Its specifications are diameter 63 mm, 75 mm, 90 mm, 110 mm, 160 mm, 200 mm, 250 mm, 315 mm. The diameter of this pneumatic equipment is more than 360 mm which can be customized.

PP duct, glass fiber reinforced polypropylene pipe. Specializing in the production, sales, and installation of FRPP ducts, the raw materials are pure and no return material is added, the equipment is advanced, and the technology is sophisticated. The FRPP ducts produced have smooth inner and outer walls, uniform texture, low fluid resistance, and strong ventilation; acid and alkali resistance, corrosion, and temperature resistance It has stable performance prevents secondary chemical reactions between the medium in the tube and the tube body, and reduces the difficulty of purification of industrial waste gas and liquid; it is non-toxic and tasteless, environmentally friendly and hygienic, non-scaling and non-bacterial, suitable for process pipelines in the food industry. Air ducts are pipes used for air transportation and distribution. In the chemical, food, and other industries, the requirements for ventilation duct systems are getting higher and higher. Metal ducts are far behind plastic ducts in terms of chemistry, hygiene, and economic efficiency. PP air ducts are widely used in the purification treatment of acid mist, alkali mist, alkaline waste gas, and organic waste gas in chemical, chemical fiber, textile, pharmaceutical, and other industries.

It is mostly used in cold air or hot air gas pipelines in ventilation and environmental protection projects. The specific industries are chemicals, building materials, power stations, glass products, etc. The sealing ring of the electric air valve is tightly processed with the same high-strength material as the valve body, which has good stability. It also has the advantages of simple structure, small operating torque and light weight, and the characteristics of rapid opening and closing, flexible actions, small operating torque, and large flow capacity are also one of the reasons for the good response of users. It can be applied to the control and adjustment of dust, flue gas, air, and fluids containing suspended particles and thick and turbid and slurry fluids, so it can be regarded as a powerful and practical component in industrial control components.

1.The wind valve material is PP and PVC, which is characterized by anti-corrosion, anti-aging, price concessions, easy installation.

2.The current manual air valve mold a molding, high strength, good sealing, smooth appearance, low resistance. Its specifications are diameter 63mm, 75mm, 90mm, 110mm, 160mm, 200mm, 250mm, 315mmd. The diameter of it is more than 355 can be customized.

8. Made of environmentally friendly materials that can be recycled.

1. It is designed and manufactured by adopting a new structural form of welding of mid-line disc plate and temporary structure steel plate. It has a compact structure, lightweight, easy installation, low flow resistance, large circulation, avoids the influence of high-temperature expansion, and is easy to operate.

6. There are no connecting rods, bolts, etc., so it works reliably and has a long service life. It can be installed in multiple positions and is not affected by the flow of the medium.

The following accessories can be selected according to different controls and requirements:

Cut-off accessories: single solenoid valve, double solenoid valve, limit switch echo device.

Adjustable accessories: electric positioner, pneumatic positioner, electric converter.

Air source treatment accessories: air filter pressure reducing valve, air source treatment triple pieces.

Manual mechanism: HVSD manual mechanism

(1) The connecting pipe size of the split multi-leaf air volume regulating valve is the same as the rectangular air pipe size stipulated by the national ventilation duct standardization.

(2) The blades of the air volume regulating valve are split-opening and forward-opening, and are used as regulating valves in ventilation, air conditioning, and air purification systems.

(3) Tested and measured, the air-tightness of the air volume regulating valve is good, the relative air leakage is about 8%, and the regulating performance is good.

Air volume control valves are widely used in industrial, mining, and civil building HVAC systems, industrial waste gas purification systems, and are one of the key equipment to control ventilation modes in various environments.
