Directional Valvesfor oil or grease
Function
The directional valves listed on the following
pages are used to control the flow of lubri-
cants, e.g. to divide up a central lubrication
system into a number of lube circuits (zoned
actuation) or to switch between circulating
and intermittently operated lube circuits.
Valves for a maximum pressure of up to about
45 bars can be used for single-line lubrication
systems with piston distributors.
Valves for a pressure range of up to 300 or
500 bars are suitable for progressive systems.

Important product usage informationAll products from SKF may be used only for their intended purpose as described in this brochure and in any instructions. If operating instructions are supplied with the products, they must be read and followed.Not all lubricants are suitable for use in centralized lubrication systems. SKF does offer an inspection service to test customer supplied lubricant to determine if it can be used in a centralized system. SKF lubrication systems or their components are not approved for use with gases, liquefied gases, pressurized gases in solution and fluids with a vapor pressure exceeding normal atmospheric pressure (1013 mbars) by more than 0.5 bar at their maximum permissible temperature.Hazardous materials of any kind, especially the materials classified as hazard-ous by European Community Directive EC 67/548/EEC, Article 2, Par. 2, may only be used to fill SKF centralized lubrication systems and components and delivered and/or distributed with the same after consulting with and receiving written approval from SKF.
