Marchesini VUBR adjustable hose burst valve, 3/8" and 1/2".
The VUBR protects against uncontrolled lowering of the load when a hose bursts: when the flow surges above the set value, the valve closes. Unlike the cartridge hose burst valve, the closing flow is adjusted from outside, on the flow adjuster; one turn is about 15 l/min. When adjusting, keep the sealing nut against the valve to avoid oil leaking.
Maximum pressure 300 bar. Zinc-plated steel body, hardened and ground steel internal parts, ball seal. Connect V to the supply and C to the actuator, as close to the cylinder as possible.
