BNSV Pressure relief valve
Overview
Also known as overpressure relief valve, it is a kind of safety protection valve. When the pressure in the equipment or pipeline exceeds the set pressure of the relief valve, it will automatically open the pressure relief to ensure that the medium pressure in the equipment and pipeline is under the set pressure, so as to protect the equipment and pipeline, prevent accidents, and play an important role in personal safety and equipment operation.
● Accurate and constant safety and stability pressure. In case of overpressure, the pressure relief valve shall be fully opened to relieve pressure in time;
● The closing speed is adjustable to eliminate pressure fluctuation;
● The diaphragm drive mechanism reduces the operation lag to the minimum;
● It can be repaired and inspected without removing it from the pipeline.
