2.4. Initial Set-up - The Pressure Reducing and Sustaining Application
The pressure reducing Application:
1.
The following is a general description of the Pressure Reducing Application - Pilot
2
a:
This pilot is designed to reduce a higher upstream pressure to a preset lower downstream pressure, and to
maintain this constant pressure regardless of flow-rate or upstream pressure fluctuations. The pilot senses the
downstream pressure through its #
1
port.
When the downstream pressure is higher than the pilot's pressure settings, the pilot increases the internal
pressure of the control chamber by letting water enter the control chamber through its port #
4
, causing the
valve's diaphragm to slightly close and decrease the downstream pressure back to the required settings level.
When the downstream pressure is lower than the pilot's pressure settings, the pilot decreases the internal
pressure of the control chamber by releasing water out to the atmosphere through port #
2
, causing the valve's
diaphragm to slightly open and increase the downstream pressure back to the required settings level.
