We provide various solutions for pressure regulation in complex fire prevention systems: from the most basic A155 and A156 pressure restricting valves to efficient pressure reducing valves characterized by two different regulation mechanisms
A221 and A223 valves are used as zone controllers in high-pressure sprinkler, standpipe, and combined systems. The pressure is controlled by a factory-set (factory set) control mechanism.
With A201, A202, A203, and A204 valves, on the other hand, the pressure is controlled by an adjustment mechanism to be calibrated in the field (field adjustable).
