Description
BP-8LF Series High Sensitivity Back Pressure Regulators
The BP-8LF Series back pressure regulator is designed to furnish high precision control of pressures in analytical instrumentation. With the combination of the large diaphragm sensing area of the BP-8 Series and the low flow of the BP-3 Series pressure control as low as 20 inches of water is easily obtainable.

- Electropolished body with better than 25 Ra finish in diaphragm cavity
- Bubble tight shutoff
- Adjustable control ranges are 6, 25, 50, 75 and 125 psig
- Proof pressure is 2 times maximum working pressure
- Burst pressure is 4 times maximum working pressure
- Weight: 3.2 lbs (1.45 kg)
- Mounting style is surface or panel (see Outline and mounting dimensions)
