What should be noted when using forged steel stop valves? It is essential to pay attention to the valve body's drainage and plug pressure relief issues. After the valve pressure test, the air in the sealing cavity of the valve body will increase and moisture will build up pressure due to the rise in environmental temperature. It is necessary to drain and relieve pressure before applying grease to ensure the smooth progress of the greasing process. After greasing, the air and moisture in the sealing cavity should be fully replaced. Timely relieving the pressure in the valve body also ensures the safety of valve use.

After the grease injection is completed, be sure to tighten the drain and pressure relief plug to prevent any accidents. During the grease injection, pay attention to the issue of even grease output. Normally, the grease outlet at the injection mouth should be filled first, then proceed to the lower point, filling sequentially. If the grease is not being outputted evenly or at all, it indicates a blockage, and it is necessary to carry out clearing and unblocking promptly.
