OPW's 476SA-0150 is a 1/2 in. male NPT vacuum breaker that is fitted with fluorocarbon seals and operates at 1-2 kPA. Vacuum breakers ensure quick draining of piping systems, and the fit into top loading valves or the suction side of pumping systems that must drain quickly and completely.
Note: The most common usage is on OPW top loading arms or with DM100 series discharge manifold for truck mounted applications.
