Clausings factor 8 Exhaust Time (Low/Medium Vacuum) K The time (t) required to exhaust a chamber at low vacuum with volume V (L), from pressure P1 to P2, using a pump with pumping speed S (L/sec) is t=2.3(V/S)log(P1/P2). In high vacuum, this is subject to the ultimate pressure limit imposed by outgassing and leakage as characterized above.

Caution Caution When the VEX3420 air operated power valve is delivered from our factory, the M5 threaded pilot ports P1 and P2 in the cover are open and the Rc1/8 pilot port in the subplate is plugged. Before connecting pipes to P1 and P2 ports in the subplate, remove the 1/8 plug from the subplate and put M5 plugs into P1 and P2 ports in the cover.
Values of pneumatic Kv are different from Cv because the testing method is different from each other. 3 3 2 2 Upstream pressure Saturated aqueous vapor flow rate Q0 [kg/h] (when Av = 1 x 106 [m2]) P1 = 1 MPa Water flow rate Q0 [l /min] (When < when Av = 1 x 106 [m2]) P1 = 0.8 MPa 1 0.9 0.8 0.7 0.6 1 0.9 0.8 0.7 0.6 P1 = 0.6 MPa Ex. 2 P1 = 0.5 MPa P1 = 0.4 MPa 0.5 0.5 0.4 0.4 P1 = 0.3 MPa
