Quick release valves can be remotely closed by hydraulic valve units operated with remote control. When operating the lever, a plunger moves a fixed volume of incompressible flow (hydraulic oil) that activates the triggers of the valves connected to the unit.
Pneumatic actuation system works by throwing out air pressure against the valve piston, which activates the trigger and instantly closes the line.
The main advantage of the pneumatic system is that it allows the closing of an unlimited number of valves from a single cabinet.
FJ offers, as a standard service, cabinets with up to 8 activations, allowing up to 8 valve lines to be activated independently.
Pneumatic actuation system is made up, in its most basic condition, of a pulse unit cabinet with every necessary actuation element inside. However, the cabinet is frequently improved with an air accumulator, which enhances the system with better trigger performance.
The electro-pneumatic drive system keeps the usefulness of the single pneumatic form but includes electrical components to include the possibility of using remote control and connectivity.
This equipment is made up by parallel solenoid valves that can be controlled using manually operated pushbuttons; this enables the user to close the valves from other systems or from control keypads.
