Operation and use of flanged stainless steel ball valves
Flange stainless steel ball valve refers to a stainless steel ball valve connected by a flange, which relies on a rotating valve to make the valve unobstructed or blocked. Stainless steel ball valves are not easily eroded by media and are widely used in various industries. Our common ball valves can be divided into carbon steel ball valves, 304 stainless steel ball valves, 316 ball valves, and copper ball valves based on their materials. The following is an introduction to their operation and use:
1) Before operation, it is necessary to confirm that the pipelines and valves have been flushed;
2) The operation of the valve is completed by driving the valve stem to rotate according to the input signal size of the actuator: when the valve is rotated forward by 1/4 turn (900), the valve is closed. When rotating in reverse for 1/4 turn (900), the valve opens;
3) When the direction indicator arrow of the actuator is parallel to the pipeline, the valve is in an open state; When the arrow is perpendicular to the pipeline, the valve is closed.
Stainless steel ball valves are widely used in various departments such as petroleum, chemical, power generation, papermaking, and people's daily lives.
