What does the model number of this valve mean?
Thread Content
Our factory has single-seat control valves that have been in use for many years; the instruction manuals for them are lost. All we have is the model numbers below. If any of you know something about them, please explain it to us. Thank you. Model: EA-GN-W84-100 15-315Lin TGL21621/CN, equipped with a pneumatic device. Model: ALP320-25-10LP02; there is also a pneumatic stop valve, PN40 DN100 – meaning the nominal pressure is 40 MP and the nominal diameter is 100 mm, right?
I’m not sure about the first question; answering the second one: “There is another pneumatic globe valve, PN40 DN100 – does that mean a nominal pressure of 40 MPa and a nominal diameter of 100 mm, right?” ” Yes, PN stands for pressure, and DN is the nominal diameter
The unit for PN is 0.1 MPa, so it should be 40 kilograms! If it’s a 400-kilogram flange, it will be very large! ! The first question still needs to be studied! !
Reply to 3# wow0011: Thank you! I really didn’t know that; thanks again!
PN40 should be 4.0 Mpa; a valve for DN100 with a weight of 400 kilograms is quite expensive and quite heavy. The pneumatic head will also be large.
