air valveProduct features:

1. The size of the connecting pipe of this regulating valve is the same as the rectangular duct size specified in the national ventilation duct standardization regulations.

2. The blades of this regulating valve are split type and are used in ventilation, air conditioning, and air purification systems

Regulating valves are superior to parallel form valves (i.e. open type).

3. Closed type multi leaf regulating valve can be used for both regulating and sealing purposes, suitable for open valves

On the requested system. For example, the fresh air valve and flat exhaust valve on the air conditioning system are also suitable for use only

Regulating valves are used in systems that require both sealing and regulation, such as primary and secondary return air valves.

4. Through experimental testing, it has been found that the regulating valve has good air tightness, with a relative air leakage rate of around 5%

Good performance.

Main technical parameters:

Temperature sensor operating temperature: 70 ° C

Fire resistance rating: 1.5h

Resistance coefficient when fully open:<0.4

Ventilation duct:

Ventilation ducts are metal or non-metal pipes used for ventilation and air conditioning engineering in industrial and civil buildings,

It is a municipal infrastructure designed to promote air circulation and reduce the concentration of harmful gases.
