Low temperature pneumatic ball valve: DQ41F, DQ41H, DQ41Y;

Installation conditions and length requirements of pneumatic butterfly valve in electrical construction
When the wire maintenance pipe is buried in the structure, the stainless steel pneumatic butterfly valve shall be used when passing through the settlement joint, expansion joint and deformation joint of the building. The pneumatic butterfly valve shall be used in the center prone to distortion, deformation and vibration, such as motor wiring
The device length of pneumatic butterfly valve should be generally within 1M, and should not be too long. The standard request for hose length has not been understood, and the detailed length should be based on your needs, generally between 500mm-1000mm
The electrical lighting conduit can be used in ordinary places with ordinary PVC series pipes. The electrical galvanized steel pipe used in the explosion-proof site depends on your construction environment and the contract you signed for construction, that is, the design request. The stainless steel pneumatic butterfly valve used for connection between the junction box and the junction box, and between the pipeline and the pipeline, as you said, has no shortcomings, but you have to consider the cost
The device length of stainless steel pneumatic butterfly valve is generally within 1M, and the standard request for hose length has not been understood. The detailed length should be based on your needs, generally between 500mm-1000mm
If the pneumatic butterfly valve device of the lighting line in ordinary public places does not need to be coated with fire retardant paint when laying, the key is to see your construction design request. No one can find defects in the construction according to the design request. Even if there is a problem, you do not have to bear much responsibility
