P54 is the body temperature, heavy rain or equal to 545 degrees, 100V is 10Mpa, that is 100 kilogramsThere are all the valves on the nameplate
Q:How to carry out the valve strength test and air tightness test?
All the factory must go through the valve pressure test, strength test for 1.5 times the nominal pressure, closed at both ends of the valve import and export, fully open the valve test pressure for 1 - 5 minutes, see the specific situation, also called low pressure seal test seal test pressure seal test, 0.6MPa. Also 1.1 times the seal hydrostatic test, specific, you see, JB/T9092 standard, very detailed

Therefore, certain closing force and closing torque must be applied, and the required opening and closing force and opening and closing torque during the valve opening process are varied, in which the maximum value is at the closing instant or the initial opening moment. Design and manufacture of valves, should strive to reduce the opening and closing force and opening and closing torque.The open torque can be obtained by means of calculation or measurement, and can be obtained by hand torque measurement.
Q:So how does the valve turn on?
The handle of the valve is opened along the pipe and perpendicular to the pipe
Q:What does the J41Y-100I valve type mean?
