Key Features
Reliable Sealing Performance for Gas Safety
The R72 back pressure regulator is designed with a precision sealing structure to help reduce leakage risk in gas control systems. Each unit can be leak tested before shipment to support safer and more reliable gas system operation.
Stable Pressure Control You Can Trust
With a compact piston design and precision-machined internal components, the R72 series helps maintain stable upstream pressure in medium-pressure gas systems, supporting smooth operation in gas panels, laboratory lines, and test equipment.
316L Stainless Steel for Longer Service Life
The wetted body and valve core are made of 316L stainless steel, offering good resistance to chemical and electrochemical corrosion. This helps extend service life in industrial gas, specialty gas, and laboratory gas applications.

FAQ
Q1: What is a back pressure regulator?
A back pressure regulator is a pressure control valve used to maintain a set pressure on the upstream side of the regulator.
Q2: How does a back pressure regulator work?
It senses inlet pressure. When the inlet pressure exceeds the set point, the valve opens and allows flow to pass downstream, helping reduce and stabilize upstream pressure.
Q3: What is the difference between a back pressure regulator and a pressure reducing regulator?
A pressure reducing regulator controls downstream pressure, while a back pressure regulator controls upstream pressure.
Q4: What is the difference between a back pressure regulator and a relief valve?
A relief valve is mainly used for overpressure protection, while a back pressure regulator is used for continuous upstream pressure control during normal operation.
Q5: When should I use a back pressure regulator?
Use a back pressure regulator when your system needs to maintain stable upstream pressure, keep minimum pressure before equipment, or control pressure in gas panels, laboratory gas lines, process systems, or test equipment.
Q6: What is the standard lead time?
The standard lead time is about 7–10 days after order confirmation. For customized configurations or bulk orders, the delivery schedule should be confirmed separately.
