Bermad mechanical pressure regulators.
The IG Adjustable Direct Control Pressure Reducer is triggered by a pressure quick to respond diaphragm, which seeks to achieve balance between hydraulic and pre-set spring strength. The IG Bermad Model PRV is built of reinforced special plastic materials that awarded it with perfect hydraulic accomplishment and excellent mechanical endurance. It reduces higher inlet pressure to lower desired stable outlet pressure despite of changing needs or changeable incoming pressure mainly for irrigation systems.
