New Product Launch: FITOK Two-Stage Diaphragm Regulators

FITOK Two-Stage Diaphragm Regulators

 

Introduction

 

 

FITOK RDDC Series Two-Stage Diaphragm Regulators feature a two-stage pressure reduction design. The combination of a metal diaphragm and a free poppet ensures excellent sensitivity and stable outlet pressure. This configuration makes these regulators ideal for low to medium flow applications that require steady outlet pressure.

 

Features

 

 

  • Lift poppet is made of Alloy C-276, offering excellent corrosion resistance
  • Metal-to-metal seal between valve body and diaphragm provides ensured sealing performance
  • Two-stage pressure reduction design ensures precise and stable outlet pressure
  • The bonnet includes a captured vent hole, allowing media to be vented to a designated location in the event of accidental diaphragm rupture
