PVB, PVBM & ZP-A Progressive Divider Valve Blocks
Bijur Delimon PVB, PVBM, and ZP-A progressive feeder blocks provide positive displacement metering for centralized progressive oil and grease systems.
Internal ground spool pistons operate sequentially under lubricant flow; any single outlet blockage stops cycle progression, triggering prompt electrical monitoring alerts.

Delimon ZVB, ZVS, and Farval Dualine (DD/DM) dual-line metering valves serve expansive heavy industrial installations spanning hundreds of lubrication points across long distances.
Capable of handling operating pressures up to 400 bar with NLGI 3 greases, each outlet pair features independent external metering screws adjustable from 0.25 to 5.0 cc per discharge.
Alternating hydraulic line pressure cycles actuate the internal spools positively without relying on return springs, ensuring supreme operational reliability.
Selection parameters: valve series, outlet ports (2 to 8), adjustable discharge displacement range, and indicator stem options.
Bijur Delimon PDI positive displacement injectors deliver pinpoint cyclic lubrication to linear guides, ball screws, and spindle bearings on CNC machines. Each injector injects a calibrated lubricant dose precisely when line pressure rises, instantly recharging when pressure drops below 1.5–2.0 bar.
Discharge outputs range from 0.01 to 1.50 cc per shot. Available as standalone cartridges or pre-assembled manifold blocks from 2 to 8 ports with nickel-plated bodies and Viton/FKM seals.
Selection parameters: output discharge per cycle (cc), port connection thread, manifold outlet count, and fluid compatibility.
Bijur Delimon single-line resistance (SLR) Meter-Units (types F, FJB, FT, FJA) provide proportional flow dividing in continuous and cyclic oil lubrication circuits. Precise spiral-channel metering pins control proportional flow distribution with flow rates designated from size 000 to 5.
Integrated spring-loaded check valves prevent pipeline draining and dry starts during machine idle, maintaining instant hydrodynamic lubrication at every startup.
Selection parameters: body style (F, FJB, FT), flow rate number (000 to 5), port thread, and tubing diameter (4 mm, 6 mm).
High-Speed Spindle Air-Oil Micro-Lubrication Systems
Bijur Delimon Air-Oil streak lubrication units are engineered for high-speed motorized spindles and grinding heads operating at speed factors up to 2,000,000 dm·N.
Micro-metered oil droplets (0.01 to 0.03 cc) are transported as a continuous streak along inner tube walls by dry compressed air streams, coating ceramic and steel rolling elements with a continuous micron-thin oil film while providing convective cooling and sealing against coolant ingress.
Selection parameters: spindle lubrication points (1 to 8), compressed air supply pressure, optical oil streak sensors, and micro-injector sizes.
SMAC & PSC-4 Electronic Lubrication Controllers and Sensors
Bijur Delimon SMAC and PSC-4 solid-state micro-controllers provide automated cycle timing and diagnostic protection for single-line, dual-line, and progressive lubrication networks.
Programmed by elapsed time or machine cycles, they monitor pump run intervals, line pressure build-up times, and decompression thresholds, outputting alarm interlocks to machine CNCs upon low level, pressure failure, or blocked divider valves.
Selection parameters: controller model, supply voltage, sensor input configuration, and programmable pause/run time ranges.
Engineering Data Required for Bijur Delimon System Sizing
Machine tool or industrial equipment model (machining centers, presses, rolling mills, conveyors), total number of lubrication points, friction kinematic type (linear roller guides, ground ball screws, journal or spherical bearings), lubricant classification (mineral oil viscosity ISO VG or NLGI 000–3 grease), and desired cyclic intervals.
Genuine Metering Valves, Spare Parts, and Accessories
We supply genuine positive displacement injectors (PDI), single-line resistance meter-units (SLR), high-pressure replacement pump elements, filter cartridges (63671 series), pressure switches, cycle monitoring sensors, and high-pressure compression fittings according to factory part numbers.
Bijur Delimon Lubrication Architectures and Application Criteria
Bijur Delimon International manufactures four core centralized lubrication architectures: single-line resistance (SLR), positive displacement injector (PDI) networks, progressive divider systems (PVB), and heavy dual-line systems (ZVB/Farval Dualine).
For compact CNC machining centers using liquid oil, PDI and SLR systems provide micro-metered delivery to linear ways and ball screws.
Heavy metallurgical plants, hot strip rolling mills, and continuous casters rely on dual-line circuits capable of driving NLGI 3 greases across long pipeline runs at pressures reaching 400 bar without pressure drops.
Operating Principles and Cycle Verification in PVB Progressive Dividers
Bijur Delimon PVB and PVBM progressive divider valves operate sequentially under incoming hydraulic lubricant pressure. Each ground spool piston travels through its full stroke before porting fluid to actuate the succeeding spool in the block.
If any delivery line or friction point becomes clogged, the entire divider block locks hydraulically. An integrated inductive cycle sensor immediately reports the stall condition to the machine CNC control, halting feed axes to prevent bearing seizure and catastrophic mechanical breakdown.
Modern CNC milling and grinding spindles rotating up to 40,000 RPM cannot tolerate grease packing due to violent hydrodynamic shear heating. 03 cc) into continuous streams of clean dry compressed air.
The oil travels as a surface wave streak along inner tube walls, coating precision ceramic or steel bearing raceways with a continuous micron-thin elastohydrodynamic film while positive air pressure cools the spindle and seals out abrasive grinding dust and liquid coolant.
Delimon ZVB Dual-Line Metering Valves in Severe Operating Environments
In steel mills and cement plants, lubrication headers often extend hundreds of meters amidst high ambient radiant heat and abrasive slag scale. Delimon ZVB dual-line feeder valves utilize two independent main supply lines pressurized alternately by a reversing valve.
Without internal spring returns, the spools are shifted positively in both directions by full system hydraulic pressure up to 400 bar. 0 cc per point.
Single-Line PDI Injectors and SLR Meter-Units for Machine Tool Slides
Single-line systems from Bijur Delimon deliver cyclic oiling to automated machine tools. 0 bar.
SLR resistance meter-units utilize calibrated spiral restrictor pins to distribute proportional continuous or intermittent oil flows, featuring internal check valves to prevent vertical tubing run drainage during standstill.
Lubrication Automation and Fault Diagnostics with SMAC Controllers
Bijur Delimon SMAC and PSC-4 electronic controllers synchronize lubrication timing with machine cycles. The controller monitors pressure rise intervals, verifies decompression periods for PDI injector reset, and logs feedback pulses from progressive divider cycle switches.
If a supply line breaks, lubricant reservoir runs empty, or a metering valve blocks, the controller opens dry alarm contacts to interlock machine cycle starts, shielding vital machine elements from dry friction damage.
Maintenance Protocols and High-Efficiency Lubricant Filtration
Long-term reliability of Bijur Delimon centralized lubrication systems depends directly on lubricant cleanliness. Up to 85% of valve spools and pump failures stem from solid particulate contamination introduced during manual replenishment or lubricant aging.
High-efficiency 63671 filter elements with 25–40 micron ratings are installed on pump suction and pressure lines. Regular reservoir cleaning, relief valve pressure checks, and FKM seal maintenance ensure years of dependable performance.
