the cartridge needle valves can be set and locked to restrict flow in both directions.
a typical use is the speed control of cylinders or other actuators.
the flow's fine adjustment and complete shut-off allow the valves to be used for snubbing pressure gauges and for use as shut-off valves.
the poppet/adjuster can be screwed out to open the valve and set the level of throttling required in either flow direction, port 2 to port 1, or port 1 to port 2.
rated flow :
max. pressure :
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 08-02
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.
