The invention relates to vacuum engineering. Valve consists of body with two branch pipes for connection to mains of vacuum pump and volume being pumped out, seat at inlet of branch pipe of volume being pumped out, plate with gasket, main spring, silphon, rod and mechanism for rod lifting. Mechanism for rod lifting is arranged as toothed-rail gearing, at that there is spring-electromagnetic unit for rod disengaging in the gearing, it is arranged as ratchet and pinion, this at valve de-energization releases the rod, this closes at that with plate, under effect of main spring, seat of inlet of branch pipe of the volume being pumped out.
