Pressure relief valve

500X-16Q is a flange connected pressure relief valve with a nominal pressure of 1.6MPa, and the valve body material is ductile iron (Q). It can automatically maintain the pressure of the pipeline system at the set value, automatically release pressure when overpressure occurs, and close the pressure holding when low-pressure occurs. With a compact structure and sensitive action, it is widely used in water supply and drainage, fire protection and other systems to ensure pipeline safety.
