What is the selection principle of the forged steel globe valve?
The selection principle is as follows: 1. Forged steel globe valves should be used on the pipeline or device of high temperature and high pressure medium. Such as thermal power plants, nuclear power plants, high-temperature, high-pressure pipelines of petrochemical systems. 2. On the pipeline where the flow resistance is not strict on the pipeline. That is, […]
You Have to Know The Knowledge Of Forged steel valve
1. Opening and closing function – cutting or communicating the flow of fluid in the pipe; 2, the adjustment function – adjust the flow rate and flow rate inside the pipe; 3, throttling effect – the fluid passes through the forged steel valve to produce a large pressure drop; 4, other functions – a. automatic […]
What Is The Grease Filling of Seal Bonnet Forged Steel Valves
The operation of Seal Bonnet Forged Steel Valves grease injection needs to pay attention to the change of pressure. When the Seal Bonnet Forged Steel Valves is in the grease injection operation, the semi-free floating float steam trap has a peak-to-valley variation. The pressure is too low, the seal leaks or the safety valve fails, […]
