Sensitive Diaphragm Regulators

DSC Series

Introduction

RDSC Series Sensitive Diaphragm Regulators feature a single-stage pressure reduction design and a large-diameter diaphragm to enhance sensitivity to pressure fluctuations, making them ideal for low-flow, high-sensitivity applications.

Features Sensitive Diaphragm Regulators RDSC Series

◎ Lift poppet and diaphragm are made of Alloy C-276, offering excellent corrosion resistance
◎ 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 an accidental diaphragm rupture
