Single Stage Regulator Diaphragm

Pressure regulators reduce an inlet pressure to a desire outlet pressure and maintain this outlet pressure even with fluctuations in the inlet pressure, and they are widely use in various piping systems. FITOK have three series of single-stage regulators: RDSC series, RDGH series and RDGN series. All three regulators ensure excellent sensitivity and stable outlet pressure through a combination of metal diaphragm and free poppet.

RDSC Series Sensitive Diaphragm Regulators feature a large-diameter diaphragm to enhance sensitivity to pressure fluctuations, making them ideal for low-flow, high-sensitivity applications. RDGH Series Medium Flow Diaphragm Regulators are suitable for various gas media with medium to high flow. RDGN Series High Flow Diaphragm Regulators are design with a reset spring to maintain stable and low outlet pressure, even under high flow conditions, making them ideal for various gas media with high flow.

RDSC Series Sensitive Diaphragm Regulators

  • Lift poppet and diaphragm is made of Alloy C-276, offering excellent corrosion resistance
  • Metal-to-metal seal between valve body and diaphragm provides ensured sealing performance
  • Reinforce diaphragm design extends diaphragm service life
  • The bonnet includes a capture vent port, allowing media to be vented to a designated location in the event of an accidental diaphragm rupture

RDGH Series Medium Flow Diaphragm Regulators

  • Large diameter diaphragm to enhance pressure sensitivity
  • Balance poppet design reduces SPE
  • Metal-to-metal seal between valve body and diaphragm provides ensure sealing performance
  • Reinforced diaphragm design extends diaphragm service life
  • The bonnet includes a capture vent port, allowing media to be vente to a designate location in the event of accidental diaphragm rupture
