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.

2. 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 direction of the medium.

use:

This butterfly valve is a non-closed butterfly valve, which is widely used in the production process of building materials, metallurgy, mining, electric power, and other production processes on pipelines with a medium temperature of ≤300℃ and a nominal pressure of 0.1Mpa to communicate, open and close or adjust the amount of medium.

Electric rectangular duct damper is suitable for chemical plants, laboratories and other application environments with explosion-proof requirements. It is used in PP material ventilation duct systems and is connected with PP air ducts. It is used for corrosive gas extraction and exhaust control, anti -corrosion, acid and alkali resistance , PP plastic manual rectangular duct damper complete specifications, supporting PP duct, elbow, tee, variable diameter use, constitute a complete PP ventilation duct system.

Electric rectangular duct damper is a kind of non-sealed butterfly valve, which is widely used in universities, chemical, biological, electric power, energy, environmental engineering, etc. in the production process, the medium temperature is less than or equal to 90 ℃, and the nominal pressure is less than 0.1Mpa. It is usually installed on the top of the fume hood, the PP suction hood and the inlet of the pipeline of the one-use-one-standby spray tower to switch the exhaust gas flow direction of the spray tower.

Structure of PP plastic manual rectangular duct damper

Square structure, flange connection.

Electric rectangular duct damper performance characteristics:

• PP material processing, acid and alkali corrosion resistance, strong anti-corrosion performance;
• PP square duct damper is designed with sockets at both ends, and flange connection can also be welded;
• High-strength actuator, all-copper design, switch life more than 20,000 times;
• The inner and outer walls are smooth and the wind resistance is small.
