Griffco Valves

BACK PRESSURE VALVES
G-Series Back Pressure Valves
Griffco 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. Robust 
construction ensures reliability in the rigorous service of 
municipal and industrial applications. Wetted materials
include:  PVC, CPVC, PP, PVDF, PTFE, 316 SS, A 20 and 
Hast. C. Available sizes: 1/2  -  2”.

M-Series Back Pressure Valves
Griffco's® new molded Noryl top extends the temperature and pressure rating of the standard valves. New valve designs continue 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-siphon valve. New construction ensures increased reliability in the rigorous service of municipal and industrial applications. 

Wetted materials include:
PVC, CPVC, PP, PVDF, PTFE, 316 SS, A 20 and Hast. C. 


Available sizes: 1/4" - 1/2”.
