The PV-LOK PVP Pipe Restraint System may successfully be used for the restraint of push on bell joints for ductile iron pipe meeting ANSI/AWWA C150 and C151 in nominal diameters 4-16". Rated pressure of the restraint is limited to the pressure stated below for ductile iron piping systems.
SIGMA offers the highest pressure rating of a serrated bell joint restraint device in the AWWA industry.
