Coval - Self-regulating Vacuum Pumps (pneumatic vacuum and blow-off control), GVMAX P1 series

Self-regulating Vacuum Pumps (pneumatic vacuum and blow-off control), GVMAX P1 series

Presentation: . Nozzle Ø : 2.5 mm
. 3 levels of vacuum : 50% - 75% - 90%
. Suction flow rate : up to 360 Nl/min
. Vacuum regulation function

Communication between both elements, pneumatic vacuum switch and gripping valve control allows the consumption of compressed air to be regulated and in particular significantly reduced. This range of vacuum pumps is strongly recommended for gripping airtight products, holding, and for medium or long cycles in explosive environments. Pneumatically controllable blow-off is integrated for release.
Note: The volume of the piping must not exceed 10 litres. For bigger volumes, please consult us.

Operating Principle: When the selected vacuum level is reached, the compressed air supply stops. This interruption does not have any effect on the operation in progress as the no-return valve maintains the vacuum and thus the grip. The vacuum switch continually analyzes the vacuum requirements. As soon as the minimum threshold is reached, it activates the vacuum generation valve. The chosen level of vacuum is immediately re-established.

Safety: The GVMAX P1 has two non-return valve functions installed as standard which enables it to maintain the vacuum within the circuit if the pneumatic power is interrupted. This function guarantees maximum safety conditions for operators during handling.
