Product: VSG4-KR Lubricating Device
1. High Quality: High strength carbon steel as main valve house, reaching the maximum operation pressure to 400bar/5800psi to each feed outlets.
2. Strictly Tested: Using 32# or 46# mineral oil tested, thinner than greasing oil. Guarantee lubricates the long distance lubrication spots completely, 100% tested for each valve.
3. Standard Dimensions: The standard industrial installation dimensions will be easily to replace and saving repair cost largely for annual overhaul of equipment.
Lubricating Device VSG4 Introduction
Lubricating device VSG4 is two line lubricating used for centralized lubrication system, with tow supplying grease or oil piping and four feeding outlets.
Lubricating device VSG4-KR is used of media for cone penetration of not less than 265 (25°C, 150g) 1/10mm grease (NLG I0 # ~ 2 #) or greater than the N68 lubricant viscosity grades , the use of ambient temperature is -10°C ~ 80°C ; such as the use of media for the oil , please use the 20MPa pressure. The two inlet ports are connecting with two supplying piping and two inlet ports are connected each, one should be blocked if not used like feeding oil outlets at certain time.

Place of Origin:
Lubricating Device VSG4 Position of Lock Screw Condition
A – Lock screw
B – Rotary slide horizontal: 2 outlets
– Rotary slide vertical: 1 outlet
With the two main lines being relieved (i.e. when the pump is switched of) the lock screw A can be closed and the rotary slide B can be turned through 90°. If the rotary slide is put into position 1 the connecting passage between the two outlets is closed, and the lubricant is discharged by the two outlets. If the rotary slide is in position 2, the connecting passage is open. In this case one of the two outlets has to be closed by means of a closure plug, and then the double lubricant volume is discharged by the other outlet.
Lubricating Device VSG4 Working Operation Graphic
Pressurized lubricant is supplied to the metering device via main line I. The control piston (1) starts moving in the direction of arrow A, displacing the lubricant in front of the control piston into the relieved main line II.
When the control piston (1) uncovers the connecting passage (2) lubricant is transferred to the right end of the dispensing piston (3), thereby displacing it to the left in the direction of arrow A.
The lubricant volume ahead of the dispensing piston is transferred via the connection passage (4) to the lubrication point. With the dispensing piston in its terminal position, the pressure in main line I will continue to rise to reach the preset change-over pressure of the two-line system. At this stage,the change-over valve of the system operates to connect main line I which has so far been under pressure to the lubricant reservoir of the lubrication pump.
At the same time the change-over valve connects main line II to the lubrication pump, thus pressurizing the lubricant in this main line. The control piston (1) moves in the direction of arrow B, displacing the lubricant ahead of the control piston into the relieved main line I.
When the control piston (1) uncovers the connecting passage (5) lubricant is transferred to the left end of the dispensing piston (3) and displaces it to the right in the direction of arrow B. The lubricant ahead of the dispensing piston (3) is transferred via the connecting passage (6) to the lubrication point. With the dispensing piston (3) in its terminal position, the pressure in main line II will continue to rise to reach the preset changeover pressure of the two-line system. At this stage, the change-over valve will once again cause a pressure changing-over in main lines I and II and the cycle will be repeated as described in stage 1.
Lubricating Device VSG4 Output Volume Adjustment
Variation KR for infinitely variable adjustment and visual indication.Infinitely variable adjustment of lubricant output is achieved by turning the adjustment screw F. Maximum output is available if the lock screw E and the adjustment screw F are in their uppermost position. By turning the screw downward the output can be continuously reduced. With the two screws in their fully closed position, the indicator pin G is completely restrained and, because the pin is attached directly to the dispensing piston, the lubricant output will be nearly zero.
The indicator pin shows the correct functioning of a pair of outlets. After setting the lubricant output, the adjustment screw F will be locked in position by means of screw E.
To secure the setting, lock the adjusting screw only when the indicator pin is retracted.
