Diaphragm Regulators High Flow
RDGN Series
Introduction
RDGN Series High Flow Diaphragm Regulators feature a single-stage pressure reduction design with a combination of metal diaphragm and free poppet for excellent sensitivity and stable outlet pressure. The reset spring configuration maintains stable and low outlet pressure, even under high flow conditions, making these regulators ideal for various gas media with high flow.
Features Diaphragm Regulators High Flow RDGN Series
◎ Large diameter diaphragm offers enhanced pressure sensitivity
◎ Metal-to-metal seal between valve body and diaphragm provides ensured sealing performance
◎ Reinforced diaphragm design extends diaphragm service life
◎ The bonnet includes a captured vent port, allowing media to be vented to a designated location in the event of accidental diaphragm rupture
