WUVPB-3 ...主要用于需要非常低?p的卸載能力（ON / OFF）。低?p
值會導致油的加熱較少，因此導致用戶的能源成本降低。
Series WUVPB-3 .../ WUVPZ-3 ... valves are size 10 solenoid controlled screw-in pressure relief cartridge valves for cavity
type DD.
They are of two-stage design, with a seated pilot stage and a sliding spool main stage.
Using only the external adjustment, a higher pressure p1 (relief setting) and a lower pressure p2 (a second relief
setting or, alternatively, unload) can be adjusted smoothly and independently, and either pressure can be activated.
The WUVPB-3 ... is principally applied where an unloading capability with very low ?p is required (ON / OFF). The low ?p
value results in less heating of the oil and therefore in lower energy costs for the user.
The WUVPZ-3 ... is principally applied where switching between two different pressures is required (HI / LO).
When the pilot stage is active (solenoid energised = pressure relief function), pilot control oil is drained within the valve to the Z
port. Port B can therefore be put under pressure without having any effect on the valve setting.
Form tools are available for sale or hire, should customers wish to manufacture their own blocks or subplates.
For direct pipe-mounted applications, the line- and manifold mounting body type DD-12 (G 1/2") can be used.
WUVPZ-3 ...主要用于需要兩種不同壓力之間切換（HI / LO）的場合。
當先導級激活（電磁閥=減壓功能）時，先導控制油在閥內(nèi)排入Z
港口。因此，端口B可以被施加壓力而不會對閥門設置產(chǎn)生任何影響。
如果客戶希望自己的塊或子板，可以出售或租用表單工具。
對于直接管道安裝的應用，可以使用DD-12（G 1/2“）的管路和歧管安裝體。
Two-pressure valve, ON / OFF or HI / LO
External pilot drain via port Z; secondary port can be pressurised
Coils can be changed without opening the hydraulic envelope
WUVPB-3 ... gives very low back pressure when unloaded
Very good price/performance ratio
Available in line mounting body DD-12 (G 1/2")
