Success hydroparts suppliesoffers pilot operated check valves, type nrp. These are available iin different sizes these check valves are available;10, 20 and 30; pressure315 bar; and flow80 to 320 lpm. Some of the ggeneral features of these check valves include: pilot operated check valve with puppet and decompression having internal drain; for threaded connection and for subplate mounting; and cracking pressure can be selected. Functional configuration of the valves isdescription: nrp type valves are pilot operated puppet valves, a to b is free flow and b to a flow is possible if pilot pressure is connected to x port; when x gets pressure, spool moves and opens pilot puppet, which allows flow from b to a; and when spool moves further it opens the main puppet and full flow from b to a is possible. Technical data: temperatureup to 80°c; hydraulic fluidmineral oil; viscosity2.8 to 300 cst; and flow80, 160 and 320 lpm respectively for size 10, 20 and 30.
