Apollo Valves A127 Series Automatic Control Valves

Automatic Control Valves | Pressure Reducing

Apollo Valves Automatic Control A127 reduces a higher upstream pressure to a constant, lower downstream pressure regardless of fluctuations in supply or demand. The normally open, spring loaded pilot, sensing downstream pressure, responds to changes in pressure and causes the main valve to do the same. The net result is a constant modulating action of the pilot and main valve to hold the downstream pressure constant. The pilot system is equipped with an opening speed control that fine tunes the valve response to the system variables. Proudly made in the USA.
