Flanged stainless steel ball valve operation and use


Stainless steel ball valve refers to a stainless steel ball valve connected with a flange, and the valve is unblocked or blocked by rotating the valve. Stainless steel ball valves are not easy to be eroded by the medium and are widely used in various industries. The cracking of the valve body is generally caused by freezing. When the weather is cold, the valve must be insulated, or the water in the valve and pipeline should be drained after production is stopped. The packing gland is broken, the force when pressing the packing is uneven, or the gland is defective, and the bolts should be tightened symmetrically when pressing the packing. Damage to the handwheel, impact or strong operation of the long bar, the attention of the staff can be avoided.

The following introduces the operation and use of flanged stainless steel ball valve operation:

1) Before operation, make sure that the pipeline and valve have been flushed

2) The operation of the valve is completed by driving the valve stem to rotate according to the size of the input signal of the actuator: when it rotates 1/4 turn (900) in the forward direction, the valve is turned off.

3) When the direction indicating arrow of the actuator is parallel to the pipeline, the valve is open; when the indicating arrow is perpendicular to the pipeline, the valve is closed
