RELIANCE 45C913 Vibration module
Here is a table with general information about the sealing properties of CH valves and components with leak proof seat design; the allowed leakage tolerance may change depending on the design, number of poppets and valve size; this general information is given for guidance only and, for many valves, specific details about the permissible leakage tolerance can be found in the relevant data sheet.
Internal leakage
The LEAKAGE for different valve families is expressed in cm3/min, or drops/min and is measured in the specified test conditions. The ratio between cm3 and drops is approximately: 1 cm3 (or 0.06 in3) = 15 – 18 drops. For pressure relief valves the leakage is indicated at re-seating conditions, identified as X% of pressure relief setting.
