High-Flow Back Pressure Valves
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.
