Spraying can be applied to a single part or multiple parts at the same time. The integral valve seat metal seal pneumatic ball valve developed by our company in 2001, the ball and valve seat are coated with I-t-VOFJKll2, with hardness of~70HRC, and the life test is 20000 times. The sealing condition is good, and users have achieved good results. The integral valve seat metal seal pneumatic ball valve can truly eliminate leakage, improve work efficiency, and make maintenance safer and downtime shorter.

What are the installation conditions and length requirements of pneumatic butterfly valve in electrical construction
The electrical lighting conduit is generally PVC series pipe in ordinary places. The electrical galvanized steel pipe obtained in the explosion-proof field is used. The specific type of pipe to be threaded depends on your construction environment and the contract signed by your construction, that is, the design requirements. There is no problem with the pneumatic butterfly valve used for connection between the junction box and the pipeline, but the cost must be considered.
The installation length of pneumatic butterfly valve is generally within 1M, and there is no clear specification for the hose length. The specific length should be based on your needs, generally between 500mm-1000mm.
The installation and laying of pneumatic butterfly valves for lighting lines in ordinary public places that do not need to be coated with fire retardant coating depends on your construction design requirements.
When the wire protection pipe is buried in the structure, the pneumatic butterfly valve shall be used when passing through the settlement joint, expansion joint and deformation joint of the building. Pneumatic butterfly valves shall be used in places prone to distortion, deformation and vibration, such as motor wiring.
The installation length of pneumatic butterfly valve is generally less than 1M, and should not be too long. There is no clear specification for the length of hose. The specific length should be based on your needs, generally between 500mm-1000mm.
