The VacLoc is a combination modular vacuum check valve and a sequence blow valve incorporated in a perfectly aligned, one-piece cartridge body featuring electroless-nickel plated valve seats for long life. An internal orifice provides balanced blow-off air flow so that several unites can be supplied and controlled by one solenoid valve.
Pilot Controlled Quick Release OptionThe pilot controlled quick release option for VacLocs work the same as the normal models except compressed-air is not used to release the work object. Using compressed air to release the work object increases air consumption by quite a bit compared to the amount used to generate vacuum. The PQR option uses a valve which is actuated by a compressed air signal that can be connected to all PQR valves in a system without concern for balancing pilot lines. The only compressed air flow is a small amount to pressurize the pilot lines to all PQR valves. The pilot signal shifts the PQR valve which opens a large passage from the vacuum port to atmosphere to immediately dissipate vacuum and release the work object.
The PQR option is available for VacLoc’s with or without an integral pump.
