needle valve with reverse check>inc-捕鱼平台游戏
the cartridge needle valves can be set and locked to restrict flow in one direction.
a typical use is the speed control of cylinders or other actuators.
the flow's fine adjustment and control in one direction allow the valves to be used for regulating the inlet and outlet flow in one direction.
the poppet/adjuster can be screwed out to control the valve's opening portion and set the level of throttling required from port 2 to port 1.
free flow maintains from port 1 to port 2.
rated flow :
max. pressure :
0.3 ml/min (5 dpm)
working temperature :
min. -20鈩?, max. 90鈩?, with standard bunan gaskets
min. -20鈩?, max. 120鈩?, with optional viton gaskets on request
best use mineral oil with viscosity ranging between 10 and 200 cst
25 micron or better
see cavity data 12-02
before screwing the cartridge on the valve body, ascertain to provide suitable gasket lubrication with clean oil and also be sure to screw the cartridge manually in to reach against the gaskets in the valve body.
