VICKERS液压阀DGMPC-5-ABK-BAK-30产品介绍
General Description
These valves are single or dual check units. Dual check units have identical check elements located in the “A” and “B” cylinder port lines. The check valve poppets are moved into the open position by a central pilot control spool which moves toward one check or the other, depending on which port is pressurized.
The check valve located in the return circuit is opened by the operating pressure in the primary circuit. When the pressure in the pilot line is vented, the check valve will remain closed.
The pilot spool area to valve seat ratio is 3:1 on standard models, and 20:1 on models with the decompression feature.
Check valve cracking (opening) pressures of 1 bar (15 psi), 2,5 bar (36 psi) and 5 bar (73 psi) are available. Please note that back pressure on the downstream or free-flow side of the pilot check valve may prevent the valve from opening in certain situations. (Back pressure opposes pilot pressure trying to open the valve.)
一般说明
这些阀是单向或双向止回阀。双检查单元在“ A”和“ B”气缸端口线中具有相同的检查元件。止回阀提升阀通过中央先导控制阀芯移动到打开位置,该阀芯根据向哪个端口加压而向一个或另一个止回阀移动。
位于回流回路中的止回阀通过主回路中的工作压力打开。当先导管路中的压力释放后,止回阀将保持关闭状态。
先导阀芯面积与阀座之比在标准型号上为3:1,在具有减压功能的型号上为20:1。
可用的单向阀开启(开启)压力为1 bar(15 psi),2,5 bar(36 psi)和5 bar(73 psi)。请注意,先导单向阀下游或自由流动侧的背压在某些情况下可能会阻止该阀打开。(背压与试图打开阀门的先导压力相反。)
