Pressure regulator also known as self-regulating valve, it is a kind of regulating valve without external power supply and secondary instrumentation, it relies on the pressure of the medium flowing through the valve itself as an energy source to drive the valve to work automatically, used to regulate the industrial automation process control in the field of media flow, Pressure, temperature, level and other process parameters to ensure stable operation of the system. Emerson produces regulators including direct-acting and conductor-acting regulators, widely used in industrial, air separation, steam, oil stations, tanks, gas and clean industry.

ANDERSON GREENWOOD Integrated Flame Arrester and Breather Valve is a safety device that combines flame arrester functionality and breather valve functionality. It is widely used in storage tank systems to ensure the safety of tanks under overpressure or vacuum conditions, while preventing external flames from entering the tank and causing hazards.

Breathing valves are classified into progressive and full-opening types. EMERSON ENARDO produces progressive breathing valves that open gradually as the overpressure increased.

The emergency relief valve is used to handle overpressure that cannot be handled by the standard vents. ENARDO emergency relief valves are well dimensioned and designed to meet API 2000 standards for emergency venting in case of fire and are very convenient for tank inspection and maintenance.

The Y-shaped integral forging high-pressure globe valve produced by YARWAY has become the designated brand of globe valves for all pipeline applications in modern high-pressure power plants. Which are renowned for their excellent cost-effectiveness, rapid serviceability, and extended service life.
