Operating Conditions

This device is applicable to a double-line centralized lubrication system with a nominal pressure of 20 MPa. As a metering oil supply device, it directly supplies oil to the lubrication points by being pushed by the alternating supply pressure of the two oil supply pipes, achieving the function of quantitatively distributing lubricating grease to each lubrication point. The SSPQ-L type bidirectional oil distribution valve has oil supply ports on both the front and bottom. The piston of the distribution valve moves in opposite directions, and lubricating grease is discharged from the oil supply ports on the front and bottom respectively. Compared with the DSPQ type distribution valve, the number of oil supply ports of this type has been doubled. A screw is pre-embedded at the lower right position of the oil supply port for the SSP0-L2, 3, and 4 series of distribution valves, which can be combined into one port to facilitate changing to an odd number of oil outlets, making the system piping simpler. The distribution valves of these three series have the same number of oil supply ports and the same installation dimensions on the front and bottom, making it easy to change the model and facilitate replacement. 

This type of distribution valve can directly observe the working condition of the distribution valve through the movement of the indicator rod, and the oil output of each oil supply port can be conveniently adjusted within the specified range by adjusting the screws.
