Griffco BPHF Valve

High-Flow diaphragm back pressure valves apply a pre-set back pressure in a chemical system.

SERIES DETAILS:

Griffco High-Flow diaphragm back pressure valves are designed to enhance the performance of chemical feed systems by applying a continuous back pressure to the chemical feed pump, while also acting as an anti-syphon valve. Larger orifice size makes the valves ideal for use with higher viscosity fluids.
