2pc Flanged Ball Valve Operation And Use

2PC Flanged Ball Valve are stainless steel ball valves connected with flanges. They rely on rotary valves to open or close the valves. Stainless steel ball valves are not easily eroded by media and are widely used in various industries. Cracks in the valve body are generally caused by freezing. In cold weather, the valves should be insulated, or the water in the valve and pipeline should be drained after stopping production. The packing gland is broken, the force applied when tightening the packing is uneven, or the gland is defective. The bolts should be tightened symmetrically when tightening the packing. Damage to the handwheel, impact, or strong operation with a long lever can be avoided with the attention of the staff. The following describes the operation and use of flange stainless steel ball valves: 1) Before operation, make sure that the pipeline and valve have been flushed. 2) The operation of the valve is completed by rotating the valve stem according to the input signal of the actuator: when it rotates 1/4 turn (90°) in the forward direction, the valve is closed. 3) When the direction indicator arrow of the actuator is parallel to the pipeline, the valve is open; when the indicator arrow is perpendicular to the pipeline, the valve is closed.
