• Double the Number of Discharging Ports
Only half the conventional number of distributing valves is needed for the required number of lubricating ports. This simplifies installation and the piping configuration.
• Odd Number of Ports Easily Supported
Dual discharging can be easily changed to single discharging by simply reassembling the cross-port hexagon socket head flat plug on the right end to the discharging port. (See below for details on change method.)
• Maximum Operating Pressure of 21 MPa
Application of higher pressure improves lubrication reliability and enables lubrication over a wider area.
• Same Installation Dimensions
The installation dimensions of DW-30, 40 and 50 types are all the same. This means that connections between distributing valves and resizing can be easily performed.
• Solid, Outstanding Durability
|Distributing valve size||20||30||40||50|
|Max. operating pressure (MPa)||21|
|Pressure resistance (MPa)||31.5|
|Grease Used||Centralized lubricating grease NLGI consistency #0 to #2|
|Min. operating pressure (MPa)||1.8||1||1||1|
|Discharge quantity (cm3/stroke max.)||0.6||1.2||2.5||5.0|
|Adjustment amount per rotation of adjusting screw (cm)||0.04||0.06||0.10||0.15|
Note) “Loss” refers to the amount of oil required for operating the pilot piston.When this distributing valve is used for oil, set the pressure below 10MPa.
