Electrically Operated Pressure Relief Cartridge Valve series WUVB-1LO

Pressure relief cartridge valves series WUVB-1LO… are size 1  valves with an 3/4-16UNF mounting thread. They are direct acting seat valves and are preferably used as pilot valves. Using the external pressure adjust ment, the higher pressure p1 (relief setting) and the lower pressure p2 (a secondary pressure, or the unloaded pres sure) can be varied smoothly and independently of one an other without opening the hydraulic envelope, and either pressure can be selected. The pressure-relief cartridges can be fittet in the AL cavity according to Bucher standard and also in some 3/4-16 UNF cavities from other valve man ufacturers. To prevent any pressure surges, port 1 must be routed to tank with the least possible back-pressure. Any tank pressure acting at port 1 is additive to the pressure set ting at the main port 2.
