for reducing harmful surges to protect pressure gauges.  Adaptors are not accessories to needle valves. 

 Order them referring to the table below   For the models shown here,

 only Japanese standard specifications are available

Used as stop valves for pressure gauge lines and small-capacity line.

Fluid Types Hydraulic Fluids Any type of hydraulic fluids listed in the table below can be used.

Note:For use with hydraulic fluids other than those listed above, 

please consult your Yuken representatives in advance.

F: Special Seals for  Phosphate Ester  Type Fluids  (Omit if not  required)

GCT : In-line Type Needle Valve,  Threaded Connection

2  Viscosity ranging between 15 - 400 mm /s (77 - 1800 SSU).  Oil temperatures between -15/+70°C 

(5 - 158°F).  Use hydraulic fluids which satisfy the recommended viscosity and oil temperatures given above.

Use phosphate ester or polyol ester fluid.  When phosphate ester fluid is used, 

prefix "F-" to the model number because the special seals  (fluororubber) are required to be used.

 Use fluids equivalent to ISO VG32 or VG46.  

-15/+70°C (5 - 158°F).  Use hydraulic fluids which satisfy the recommended viscosity and oil temperatures given above.

GCTR : Angle Type Needle  Valve, Threaded  Connection

Depends on allowable pressure drops.See flow vs. adjustment revolutions characteristics 

and pressure drop at full open  characteristics.

Due caution must be paid to maintaining control over contamination of the hydraulic 

fluids which may otherwise lead t o breakdowns and shorten the life of the valves. 

 Please maintain the degree of contamination within NAS 1638-Grade 1 2.  Use 25 µm or finer line filter.  Control 

Used where pressure gauges are attached directly to needle valves.  Equipped with pressure snubber
