1-173-EN Directional Valves for oil or grease 161-1-31 161-1-5 DV5-4 Function he directional valves listed on the following pages are used to control the flow of lubricants, 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 bars can be used for single-line lubrication systems with piston distributors. Valves for a pressure range of up to or 5 bars are suitable for progressive systems.
Directional valves should be selected using the following criteria: 2, 3 or 4-way valve switching functions range of valve pressures flow rate of the valves lubricant for which the valve is to be used oils with a low or high effective viscosity, greases up to NLGI grade 2. he valve data are listed in two tables, subdivided into: hydraulic and mechanical characteristics electrical characteristics.
