OPERATING SPECIFICATIONS Working Pressure 125 psi (8.6 bar) Max Temperature 150°F (65°C) Energized to open: Line pressure is directed through the solenoid to the upper diaphragm chamber, closing the valve. Activating the solenoid vents the upper diaphragm chamber, allowing the valve to open. Energized to close: The upper diaphragm chamber is vented, allowing the valve to open. Activating the solenoid pressurizes the upper diaphragm chamber, closing the valve. Independent control pressure: An independent source of pressure is used through the solenoid to control the diaphragm valve.
