The Model 1340 & 2420 Pressure Reducing Pilot controls the amount of pressure in the upper chamber of the main valve (hence, the degree of opening or closing of the main valve). The downstream system pressure is sensed under the pilot to close, increasing the amount of pressure in the upper chamber of the main valve causing it to close a proportionate amount to maintain a constant discharge pressure. As the downstream pressure decreases, the pilot begins to open, allowing the pressure in the upper chamber of the main valve to decrease, causing the main valve to open. This is a constant modulating action compensating for any change in downstream system pressure.
