About the LF back pressure regulators

Cv: 1·E-08 to 0.07  |  Max. Temperature: 300°C  |  Max. Pressure: 69 barg (1000 PSI)

 

This unit controls pressure over a very large range of flow and pressure. This unit regulates precise setpoint pressure even when the flow rate varies over 5 decades. The turndown ratio is 1:100.000 and sometimes even more. Although the units are often used at the low end of their capacity, the maximum Cv value of this back pressure regulator is 0,07. This allows the unit to control pressure at 69 bar (1000 PSI) with a flow rate close to 100.000 ln/min down to 0,1 mln/min.
