What are the usage and preservation of forged steel gate valves and their convenience? The direct sealing of forged steel gate valve is the main function of internal and external threads. Usually lead oil, linen and PTFE raw materials are taped inside to ensure that the joint is sealed. Among them, PTFE raw material has strong corrosion resistance and excellent sealing effect. Its use and preservation are extremely convenient. When it is removed, it can be removed completely, because it is a non-sticky film, much more convenient than lead oil and linen.

The grease injection operation of self-sealed forged steel gate valve needs to pay attention to the change of pressure. The grease injection pressure of self-sealed forged steel gate valve varies regularly in peak and valley with semi-free floating ball steam trap. The pressure is too low, the seal leaks or the safety valve fails, the pressure is too high, and the manufacturer of the grease injection valve is blocked.

Sealing inner grease hardening or sealing ring and valve ball, valve plate lock.
