Description
Bijur Delimon DD5 Dualine Valve - 10 Lube Points - Without Indicator Tower (Harsh Environment)
L. Dewitt's SKU #: DD510250206 | Mfr Part #: DD510250206Bearing failures, unplanned line stops, and missed manual-lube routes are the silent killers of plant uptime. The Bijur Delimon DD Dualine Valve eliminates that risk by automatically metering a precise, individually adjustable shot of oil or grease to every bearing on every pump cycle - with a positive indicator stem you can verify at a glance.
- Reliability & Maintenance Managers who are tired of chasing bearing failures and unscheduled downtime.
- Plant & Lubrication Engineers spec'ing centralized systems that need precise, repeatable, individually adjustable output.
- OEMs & System Integrators building production machinery that ships with a fully integrated lubrication circuit.
- MRO Buyers sourcing direct replacements for legacy Bijur, Farval, or other dualine divider valves.
- Maintenance Technicians & Millwrights who need standard NPT/U-81 fittings and a visible indicator stem to verify operation in the field.
The Bijur Delimon DD510250206 is a Heavy-duty (DD50 series) dualine divider valve assembly with 10 discharge ports (each valve serves 2 bearings, or 1 with cross-porting), rated to 3,500 psi (240 bar), individually adjustable, and equipped with No indicator tower (harsh-environment build). Discharge volume is fully adjustable from .18cc (.011 cu. in.) up to 4.74cc (.289 cu. in.) per piston stroke - per outlet, independent of every other outlet on the block.
How DD Dualine Valves Work
DD valves are fully hydraulic - no springs, no check valves, just two moving parts (a pilot piston and a main piston). Pressurized lubricant entering the valve forces the pilot piston down, applying pressure to the top of the main piston, which discharges a metered shot of lubricant to the bearing through the lower port. When supply-line pressure reverses, the main piston travels in the opposite direction and discharges through the upper port. Each DD valve serves two bearings by default; a simple cross-porting kit converts it to single-discharge if you need one. No system redesign is required when adding or removing lubrication points - and every output is individually adjustable.

Why Reliability Teams Choose This Valve
- Stops bearing failures before they start. Every cycle delivers a precise, repeatable shot to every bearing - no missed routes, no operator dependency.
- Verifiable at a glance. Indicator stem on every section confirms the valve is firing - your maintenance tech does not need a stethoscope or a flow meter.
- Tunable per bearing. Each output adjusts independently, so a heavily loaded spindle bearing gets more lubricant than a light idler - without adding hardware.
- No system redesign when scope changes. Add or remove lubrication points by swapping or repositioning valve blocks - the rest of the system is untouched.
- Two moving parts. No springs. No check valves. Fewer wear items, fewer failure modes, longer service life in dirty environments.
- No indicator tower - shorter, sealed profile for harsh environments where towers are exposed to impact or contamination.
Common Applications
- Centralized dualine lubrication systems on production machinery
- Steel mills, paper mills, cement plants, mining
- Heavy stamping presses and forging equipment
- Conveyor and material-handling drive systems
- OEM lubrication circuits on custom machinery
- Direct replacement for legacy Bijur and Farval dualine valves
