Model 87D Hydraulic Control Valves PN25 GGG50 Flanged

BOYUT /ÖLÇÜ / ÇAP

MODEL

Model 87D Hydraulic Control Valves are a professional control valve range developed for water distribution systems, pumping stations, process lines, reservoir supply infrastructure and industrial installations requiring higher pressure ratings and large diameters. The range combines pressure reduction, proportional pressure control, pressure sustaining, level control, flow management, pump protection, remote operation, surge prevention and check-valve functions. The GGG50 ductile iron body provides mechanical strength and reliable field performance. Flanged connections enable robust installation in large-diameter pipelines. With a PN25 rating and an operating pressure of 360 PSI, Model 87D valves serve more demanding applications than standard PN16 solutions.
