Pressure Regulator - Brass & Stainless Steel With Elastomeric & Stainless Steel Diaphragm | Single Stage, Double Stage, Reliable Pressure Control

A pressure regulator is a device which is used to reduce the pressure of gas from a high pressure cylinder or any other source to a workable level that can be safely utilised for operating equipment and instruments.

How Many types of Regulator are there

Basically two types of Regulators are used very widely. Those are

• Single Stage
  
• Double State (Two Stage)
  

• Also based on Diaphragm (an integral part of Regulator) regulators can be divided into three categories.
• Brass Pressure Regulator with Elastomeric Diaphragm: Used where contamination and diffusion is tolerable. Such as welding, gas cutting etc.
• Brass Pressure Regulator with Stainless Steel Diaphragm: Used where contamination and diffusion is not acceptable. The SS diaphragm prevents contamination and diffusion. However Brass body is recommended for mildly corrosive gases like H₂S, NO, NO₂ etc
• Stainless Steel Pressure Regulator with Stainless Steel Diaphragm: This kind is also used where contamination and diffusion is not acceptable. It is used for both non corrosive and mildly corrosive gases. It is not recommended for highly corrosive gases like Cl₂ etc.
