FITOK General Diaphragm Regulators

Introduction

FITOK RDGC Series General Diaphragm Regulators feature a single-stage pressure reduction design with a combination of a metal diaphragm and free poppet. This configuration ensures excellent sensitivity and stable outlet pressure, making these valves ideal for a variety of gas and low viscosity liquid media that feature low to medium flow.

Features

Compact design and lightweight
Lift poppet is made of Ni-Cr-Mo Alloy (UNS N10276), offering excellent corrosion resistance
Metal-to-metal seal between valve body and diaphragm provides ensured sealing performance
Reinforced diaphragm improves sealing performance and extends service life
