Corrosion is one of the important elements that cause valve damage. In valve protection, valve anti-corrosion is an important issue to be considered. For metal valves, surface coating treatment is the best cost-effective protection method.

Flanged stainless steel ball valve refers to the stainless steel ball valve connected by flange, which is unblocked or blocked by the rotary valve. Stainless steel ball valves are not easy to be eroded by media and are widely used in various industries.

In winter, the temperature drops rapidly, and the valve often freezes. At this time, if it is not handled, the pipeline will be prone to failure. Accidents may also occur under some high-risk conditions. Therefore, antifreeze treatment of valves is very important.

1) Before operation, confirm that the pipeline and valve have been flushed. 2) The valve operation drives the valve rod to rotate according to the input signal of the actuator: when it rotates 1/4 circle (90 °) in the positive direction, the valve is closed. The valve opens when it is rotated 1/4 turn (90 °) in the opposite direction.
