Vacuum Unit Pmax Vacuum pressure P1 1. If the ejectors suction port is closed and sealed tight, the suction flow becomes 0, and the vacuum pressure increases to the max. (Pmax). 2. If the suction port is opened gradually and air is allowed to flow (the air leaks), the suction flow increases, and the vacuum pressure decreases. (The condition of P1 and Q1) 3.

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.

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.

The inlet pressure obtained in the flow characteristic graph of silencer indicates the pressure (P1) prior to silencer. (Refer to the diagram below.)
Inlet pressure (IN) Pressure in diaphragm chamber When the inlet pressure (P1) is higher than the regulating pressure, the check valve w closes and operates as a normal regulator (Figure 1). When the inlet pressure (P1) is shut off and released, the check valve w opens and the pressure in the diaphragm chamber q is released into the inlet side (Figure 2).
