(Griffco) G Series Back Pressure Valve (Plastic and Metal Models)
The back pressure valve prevents siphoning and allows for pressure adjustment! It uses a highly chemical-resistant PTFE diaphragm! There is a lineup of various materials and sizes available!
This is a back pressure valve made from various materials including PTFE, PVDF, PP, CPVC, PVC, Halar, stainless steel, Hastelloy C, and Alloy 20. It has the function to prevent siphoning phenomena! It can be used in lines that require chemical resistance or high-temperature lines. Additionally, by controlling the pressure, it stabilizes pulsation phenomena and the amount of fluid injected, leading to improvements in the quality of the system or unit. Due to its simple structure, parts can be replaced and pressure adjustments can be made without removing it from the line!
