Classification:

 

Stainless steel pneumatic ball valve, stainless steel electric ball valve, stainless steel manual ball valve. The material of stainless steel ball valves is divided into 304, 316, 321 stainless steel ball valves.

 

Stainless steel ball valves rely on rotating valve cores to keep the valve open or closed. Ball valve switches are lightweight, small in size, can be made into large diameters, reliable in sealing, simple in structure, easy to maintain, and the sealing surface and spherical surface are often in a closed state, which is not easily eroded by media. They are widely used in various industries. Only its closing element is a sphere, which rotates around the centerline of the valve body to achieve opening and closing of a valve.

 

advantage:

 

1. The fluid resistance is small, and its resistance coefficient is equal to that of a pipe segment of the same length.

 

2. Simple structure, small size, and light weight.

 

3. Tight and reliable, the sealing surface material of ball valves is widely made of plastic, with good sealing performance, and has also been widely used in vacuum systems.

 

4. Easy to operate, quick opening and closing, only need to rotate 90 ° from fully open to fully closed, making it convenient for remote control.

 

5. Easy maintenance, simple ball valve structure, and generally movable sealing rings make disassembly and replacement relatively convenient.

 

When fully open or fully closed, the sealing surfaces of the ball and valve seat are isolated from the medium, and when the medium passes through, it will not cause erosion of the valve sealing surface.

 

7. It has a wide range of applications, with diameters ranging from a few millimeters to several meters, and can be used from high vacuum to high pressure.

 

Instructions for using stainless steel ball valves:

 

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 of the actuator: when it rotates forward 1/4 turn (900), the valve closes. When rotating 1/4 turn in reverse (900), the valve opens.

 

3) When the direction indicator arrow of the actuator is parallel to the pipeline, the valve is in the open state; When the arrow is perpendicular to the pipeline, the valve is in the closed state.

 

Stainless steel ball valves are suitable for those places. Maintenance:
