Restrictor valve with reverse free flow checkSandwich construction•Q max =10l/min•Q NG3-Mini
•p N max=8l/minmax =315bar
DESCRIPTION
FUNCTION
APPLICATION
one way restrictor cartridge with incorporatedcheck valve integrated in the screw-in car-where volume flows have to be controlled infree flow check. Screw-in cartridge M18x1,5tridge. The opening pressure of the check valveone flow direction according to the load. De-in accordance with ISO 7789. Type of ad-p pending on the application, a distinction isjustment available: „S“ = screw adjustment, „D“valve shut, the volume flow can be infinitelyö = 1 bar. In the other direction, with the checkmade between restricting the forward flow or= knob adjustment, „K“ = locking knob adjust-adjusted via the restrictor section as a functionthe return flow. These sandwich valves arement (see data sheet no. 2.4-610). To saveof the pressure.
particularly suitable for machine tools and alsoweight and to protect against corrosion, bothall kinds of handling operations. Mini-3 one-sandwich body and knob of cartridge are inway restrictors are used where hydraulic sy-anodised aluminium. The cartridge body isstems have to be both light and compact.
