Which is a good condenser pump in Dalian

The normal flow direction of various regulating valves of Dalian Chemical Pump is in the direction of opening the valve core (forward operation), and the manufacturer only provides the flow value and flow rate under normal flow direction with experience. The valve will generate violent vibrations and emit very harsh noise, causing the valve core to quickly disconnect. Under normal process conditions, the opening of the regulating valve is moderate.

Even a small opening is short-lived, so the regulating valve can be used safely and normally. The angle type regulating valve has a simple flow path and low resistance, making it suitable for forward application (installation) under normal working conditions. However, in high-pressure drop situations, it is recommended to use angle type regulating valves in reverse to improve the imbalance force and reduce damage to the valve core.

At the same time, it also helps with the flow of media, prevents coking and congestion of regulating valves. Angle type regulating valves are not recommended for reverse use, and are only recommended for high pressure differentials, high viscosity, easy coking, and media containing suspended particles. When operating in reverse, it is necessary to prevent prolonged operation under small opening conditions, especially during testing.
