Pilots
Pressure regulating pilots PRAL®, flow control pilots KATAL® and hydraulic relay VAR®
The hydraulic relay VAR® is designed for actuating hydraulic valves at certain distances in which the hydraulic signal alone is insufficient or excessive, to be able to operate it. However, this device allows other interesting functions such as: valve opening or closing accelerator, hydraulic relay, antitopographic valve, etc.

The pressure differential pilot KATAL® has been designed to control hydraulically operated valves. We can get a flow limiting valve, being able to perform other operations such as pipe breakage control.
Using a hole plate calculated for each situation, a single head loss is created for each flow rate that you want to limit.
