Features

• The P500 sensing pilot is used on A500 main valves for pressure sustaining and pressure relief duties
• When upstream pressure drops below the set point, the pilot closes the main valve to sustain upstream pressure
• When upstream pressure exceeds the relief set point, the pilot opens to vent excess pressure

Description

Pilot for pressure sustaining and relief duties. The P500 sensing pilot is used on A500 main valves for pressure sustaining and pressure relief duties. When upstream pressure drops below the set point, the pilot closes the main valve to sustain upstream pressure. When upstream pressure exceeds the relief set point, the pilot opens to vent excess pressure.
