R627 High Flow Gas Regulator with Internal Relief

Transcription

1 High Flow Gas Regulator with Internal Relief The Relieving Regulator has an internal relief valve that provides protection against over pressurization. As output pressure builds up above the start-to-discharge point the relief seat disengages from the diaphragm and the excess pressure is relieved through the bonnet vent port. As a result, the output pressure reduces and returns to the initial setpoint. The relief seat then reseats against the diaphragm. The action of the internal relief valve in many cases eliminates the need for an external relief valve. The is available in spring ranges from 5-0 up to The contains a relief indicator that is attached to the vent assembly. The indicator pops off the vent when the relief valve opens and serves as a visual indicator that the relief valve has operated. Applications Farm Tap Gas Gathering City Gates District Gates Maximum Bonnet and Diaphragm Casing Maximum pressure to spring and diaphragm casing to prevent leak to atmosphere (internal parts damage may occur). Maximum pressure to spring and diaphragm casings to prevent burst of casings during abnormal operation (leak to atmosphere and internal parts may occur). Maximum diaphragm casing overpressure to prevent damage to internal parts.
