DM Dualine Valves

DM Valves are dual line valves that are completely hydraulic in operation. They will deliver either oil or grease, are fully and individually adjustable in regard to discharge quantity and are equipped with operational indicators. DM series valves always have one discharge port per valve section located on the bottom of the valve. DM valves can be supplied in several basic discharge capacities and are available in blocks consisting of one, two, three or four valves.

Operation

Pressurized lubricant entering the valve forces the pilot piston down, allowing pressure to be applied to top of the main piston. The main piston begins to move down under pressure, forcing lubricant from its chamber, past the lower land of the pilot piston and out the discharge line to the bearing. When pressure in the supply line is reversed, lubricant then enters valve and forces the pilot piston up, allowing pressure to be applied to bottom of main piston, which begins to move up, forcing lubricant from its chamber, past the upper land of the pilot piston and out the second discharge line to the bearing.
