Y Type Pilot Operated Pressure Relief Y-7015

Duyar Pilot Operated Pressure Relief valve working principle: When the pressure of the sprinkler system exceeds the preset setpoint, the pilot valve senses the increase and opens the main valve, allowing excess pressure to be discharged through the outlet. Once the pressure returns to normal, the pilot closes and the main valve reseats to resume normal operation with leak-tight closure.
