The 80A-QR is a pilot-operated, universal surge-relief valve, that is designed for the pressure-surge protection of pumps, filtration systems and pipelines in mining (corrisive fluid) and agricultural irrigation applications.
The valve continuously senses the pressure in the system and keeps a drip-tight closed position as long as the pressure is low.
The valve instantly opens in case the upstream pressure has reached a set, critical value, allowing surplus flow out of the system. The closing-speed is regulated so to allow smooth and quiet attenuation of the pressure-surges.
