Features
High strength ductile iron body used for lowering the weight and improving long term durability.
Advance dynamic design of single body with diffuser provides streamline flow and assures lower head loss.
One of the lowest head loss check valve, resulting in savings towards power costs, valve disc with shorter plunger and spring reverse faster than most of check valve.
All iron parts are coated inside & outside with fusion bonded epoxy for corrosion resistance per AWWA C550.
Bronze bushing reduce wear and tear.
Hydrodynamic design with spring ensures non-slamming and prevents water hammer.
Stainless steel spring hidden in the diffuser and protected while valve is in operation.
Disc will positively close before reverse flow, and maximize the closing speed up to 0.2 sec.
Installation can be vertical / horizontal / inclined.
F/F comply with EN 558-1 Series 14.
Valves are certified NSF61 for Drinking Water and NSF72 for Lead Content.
