Pneumatic Ventilation Butterfly Valve With Heat Sink D641W/D641H

D641W/D641H pneumatic ventilation butterfly valve with heat sink is a non closed type butterfly valve, widely used in production processes such as building materials, metallurgy, mining, and power, for connecting, opening and closing, or regulating medium quality. The pneumatic ventilation butterfly valve is designed and manufactured using a new structural form of welding a center line type disc plate with a short structural steel plate. It has a compact structure, light weight, easy installation, low flow resistance, and large flow capacity, avoiding the influence of high temperature expansion, and is easy to operate. No connecting rods, bolts, etc. inside the body, reliable operation, and long service life. It can be installed at multiple workstations without being affected by the flow direction of the medium.

Application field:
Widely used in textile, chemical, petroleum, incineration plants, cremation plants, thermal power plants, machine room ventilation, medicine, food, shipbuilding, steel smelting, paper making, biotechnology, chemical fields and other places.

Execution standards:

Flange connection size: GB/T9115.1-2000
Structural length h: GB/T12221-1989
Pressure test: GB/T13927-1992; JB/T9092-1999

Performance parameters of the actuator:
Adopting a new type of pneumatic actuator, there are double acting and single acting (spring return), gear transmission, safe and reliable; The large-diameter valve adopts a series of AW pneumatic actuators with a fork type transmission, with a reasonable structure and large output torque, available in double acting and single acting types.

1. Gear type dual piston, with large output torque and small volume.
2. The cylinder is made of aluminum material, which is lightweight and has a beautiful appearance.
3. Manual operating mechanisms can be installed at the top and bottom.
4. The rack and pinion connection can adjust the opening angle and rated flow rate.
5. The actuator can be equipped with live signal feedback indication and various accessories to achieve automated operation.
6. The IS05211 standard connection provides convenience for product installation and replacement.
7. The adjustable screws at both ends allow standard products to have an adjustable range of ± 4 ° between 0°and 90°. Ensure synchronization accuracy with the valve.
