The 3 way priority valve – excess to tank is used to regulate and keep constant flow rate in one port (1 ) and send the excess flow to the second port (2), regardless of the pressure variation.
MOUNTING AND OPERATION:
Connect the actuator to 1 port and the power supply to 2 port.
Finally connect the output 3 to the tank.
The flow passes through the 2 port and exits from 1 port at the
desired flow value. The excess flow, insensitive to the pressure variation, discharging to the tank.
To increase the flow of 1 port, loosen the hand wheel X and tighten the handweel Y. Vice versa unscrew to decrease.
