General Tied Diaphragm Regulators
RSGC Series
Introduction
RSGC Series General Tied Diaphragm Regulators feature a single-stage pressure reduction design. The tied diaphragm construction provides positive shutoff. The poppet spring design improves flow characteristics, making these regulators suitable for low flow, high purity, and ultra high purity applications.
Features RSGC Series General Tied Diaphragm Regulators
◎ Lightweight, compact design
◎ Metal-to-metal seal between valve body and diaphragm ensures reliable sealing performance
◎ Reinforced diaphragm improves sealing performance and extends service life
◎ Lift poppet and diaphragm are made of Alloy 22, offering excellent corrosion resistance
◎ Tied diaphragm construction offers positive shutoff for added safety
◎ Bonnet with a captured vent port allows media to be vented to a designated location in the event of diaphragm rupture
