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.

Note 3) Hysteresis mode: When the values of P1 and P2 are the same or when |P1| > |P2| within 3 digits, the hysteresis will be automatically 3 digits for the set value of P1. Window comparator mode: The hysteresis is 3 digits, so separate P1 from P2 by 7 digits or more and set them. 1 digit is the minimum pressure display unit. (See the table above.)
