Farval FD Series

FD Series Divider Valve

FD series divider valves are designed for use with series progressive oil and grease lubrication systems. They are of two piece, steel construction with viton O-ring seals. FD valves will serve 2, 3, 4 or 6 points of lubrication. The 2, 3 and 4 point divider valves require .08 cu in to complete one full cycle. An FD-6 divider valve requires .06 cu in to complete one full cycle. The valves divide the discharge acording to the table below.

Features
+ Positive displacement of lubricant due to precise toleranced clearances.
+ Economical and compact design.
+ Simple to install on new or existing machines.
+ Bolt together construction with viton 0-ring seals between sections and piston plug.

Operation
The FD divider valve is a self-contained, multiple outlet, series progressive valve. The term progressive means that each piston must complete its stroke, discharging a measured amount of lubricant before the following piston operates. As long as lubricant is supplied under pressure to the inlet section, each piston will continue to operate in a progressive manner.
W
hen lubricant flow is interrupted to the inlet, piston movement stops. When flow resumes, piston movement commences at the same point in the discharge cycle. Feed lines deliver lubricant from the valve block to individual lube points. Should a discharge line become blocked, it will stop all the valves operating. Indicators are available to alert a blockage.
