V Series Guided Piston Relief Valve, Cast Iron, 1 NPT Ports, Spring, Up To 25.00 GPM

The sliding piston concept and internal design contours of Fulflo valves offer unique flow and stability characteristics ensuring reliable performance without chatter. Constructed from durable cast iron this valve maintains consistency with a hardened steel piston and Buna-N seals. Quiet stable and efficient performance is assured in load regulation and system protection applications. This device effectively modulates flow and pressure making it suitable for hydraulic oils water solvents and various chemicals. Fulflo guided piston valves are designed to be less responsive to transient pressure surges eliminating the tendency to pound squeal or chatter. Featuring 1 NPT ports this valve operates at a pressure range of 150-350 PSI and manages a rated flow of up to 25.00 GPM. Unlike conventional direct-acting relief valves Fulflo valves provide a proportional pressure rise with increasing flow avoiding the issues seen with spring-loaded poppet or ball check valves.
