Comparison of Recommended Ratio Values for Selection of Drain Valves

Usage occasion: Requirements for selecting magnification ratio

The lower part of the cylinder should be able to quickly remove condensed water under various pressures

Every 100m before the steam main pipe or control valve, there should be 3 drainage points at the turning of the pipe, the end of the main pipe, etc

Drainage points should be set up in front of various control valves with a branch pipe length greater than or equal to 5m

The steam water separator drains water at the lower part of the steam water separator

Generally, a drainage point 2 is set at the 15mm DN of the heat tracing pipe
