Introduction 

Overview 

- 

The BS(H)10 and BS(H)15 series are spring loaded back pressure regulators designed for the regulation 
of high pressure, high flow gases, and liquids. 

- 

For pressure and temperature rating information refer to the 

Pressure Regulators, RHPS Series

 catalog, 

MS-02-430. 

 

WARNING 
Check that system pressures and temperatures do not exceed those stated on the regulator as 
this could result in product failure.
