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.

Some models of instruments claim to have a higher * * degree, with a basic error of only (± 0.2%~± 0.3%) R. However, there are strict installation requirements and reference conditions, such as the ambient temperature of 20~22 ℃, the length of the front and rear straight pipe sections are required to be greater than 10D, 3D (usually 5D, 2D) and even proposed that the flow sensor should be integrated with the front and rear straight pipes for real flow calibration on the flow standard device, To reduce the impact of poor clamping. Therefore, when selecting and comparing multiple models, do not just look at high indicators, but read the manufacturer's samples or instructions in detail for comprehensive analysis.
