In natural gas transmission and distribution systems, valves serve as the core components for fluid control, and their selection, installation, and maintenance directly impact the system's safety, continuity, and regulatory compliance.

Features of the emergency shut-off solenoid valve: Performance features: Butterfly piston, anti-corrosion and wear-resistant, single-ring seal, leakage prevention guide setting, fault elimination,

The sealing surface of a valve is its core component. The leakage forms of the sealing surface can generally be classified into several types, namely, leakage from the sealing surface,

Valves are usually connected to pipes in various ways such as threaded, flanged, welded, clamped, and ferrule wafer. So, how should one choose when using and selecting them?

Proper selection and installation of steam traps can prevent freezing as long as there is steam passing through. However, if the steam supply is interrupted, the condensate in the heat exchanger or
