Product Details
Ventilation hot air butterfly valve
This series of products is a new product of thermal air duct and air volume adjustment. It combines the advantages of ball valve and butterfly valve. It adopts plate welding butterfly plate structure, which can smoothly and accurately adjust reasonable air volume, so that the flow characteristic is approximately equal percentage, with large adjustable range and adjustable 100:1. It can meet the installation and driving of plumbers at any position above and below, the specially designed control frame has the specific functions of convenient operation, light weight and sensitivity, and accurate positioning. The driving mode is turbine worm drive and electric drive.
The regulating butterfly valve is mainly used for regulating the flow of medium in the industry gas pipeline. The main structure is straight plate regulating and ZAJW automatic regulating butterfly valve.
Uses and characteristics, straight plate type regulating valve is suitable for cement, building materials, municipal construction, electric power and other industries for gas pipeline opening and closing and regulating medium flow, the valve flow resistance is small, flexible opening and closing, simple structure, short structure length, light weight, easy to use and maintenance.
Structure diagram (ventilation butterfly valve)
• Nominal pressure: 0.1MPa ~ 1MPa
• Applicable medium: air, flue gas, gas, etc
Applicable temperature: ≤ 300 ℃ ~ 1200 ℃
• Leakage rate: ≤ 1%
The main material of the door: carbon poetry, alloy poetry, stainless steel outline.
• The electric device is one or two-stage two-stage transmission, and can be manually operated, which can realize the requirements of on-site operation and remote centralized control.
• Connecting flange standard: GB/T9115
ZAJW type automatic adjustment butterfly valve is mainly used in metallurgy, chemical industry, energy and environmental protection industries such as gas pipeline, for the purpose of regulating medium flow. The valve all adopt steel plate welding structure, small volume, light weight, easy to install.
