Introduction
The QXV series metering devices are specially designed for single-line high-pressure centralized lubrication systems. They are compatible with lubricants up to NLGI 2 grade that suit polyurethane seals. Featuring an externally adjustable lubricant output, these devices are equipped with an indicator pin to enable intuitive visual operation monitoring. Each individual QXV metering unit can be quickly detached for routine inspection or direct replacement, facilitating convenient on-site maintenance. Additionally, every QXV metering device comes fitted with a transparent polycarbonate protective cap for reliable component protection.

Features/Equipment characteristics
1.Supplied with manifold options ranging from 1 to 6 ports to meet diverse layout demands
2.External adjustable output design enables flexible and precise lubricant dosage regulation
3.Transparent polycarbonate protective cap safeguards the indicator pin while allowing clear visual operational inspection
4.Modular structure allows easy disassembly of single units for inspection and replacement, reducing maintenance downtime
5.Adopts color-coded sleeve-based output setting system for quick, intuitive and standardized flow adjustment
Our Advantages
1.Precise, flexible external flow calibration with color-coded sleeves
Metering output covers 0.25–1.31 cm³ per cycle. Operators can rapidly switch lubrication doses via standardized color-marked sleeves without extra tools, realizing accurate dosage matching for different friction points and eliminating over-lubrication or insufficient grease supply.
2.Convenient on-site visual monitoring with protective transparent cap
The built-in reciprocating indicator pin shows real-time working status. The impact-resistant polycarbonate cover shields the pin from dust, water and debris in harsh workshops while keeping full visibility for quick manual inspection, no electrical wiring required for basic monitoring.
3.Flexible manifold layout for customized equipment layouts
Standard manifolds with 1 to 8 outlet ports are available, allowing flexible combination according to the number of lubrication points on machinery. Compact carbon steel body saves installation space for compact OEM equipment designs.
FAQ
Q1: How much lubricant can each QXV unit dispense per cycle?
A1: The adjustable metering volume ranges from 0.25 cm³ to 1.31 cm³. Different flow rates can be quickly switched by replacing corresponding color-coded adjustment sleeves, achieving standardized dosage configuration without complex calibration tools.
Q2: How do I check if QXV is operating normally?
A2: Each unit is fitted with a visible indicator pin protected by a transparent polycarbonate cap. The pin reciprocates back and forth during each lubrication cycle; static pin status indicates blockage or system failure for immediate troubleshooting.
Q3: Can I replace a single faulty QXV unit without disassembling the entire manifold?
A3: Yes. The independent modular structure enables individual disassembly of any single metering cartridge. You only need to remove the faulty unit for inspection or replacement, without disconnecting other lubrication pipelines or stopping the whole lubrication system for long periods
Q4: What material is the QXV main body made of?
A4: The standard housing is carbon steel with stable mechanical strength to sustain long-term high-pressure operation. For corrosive humid environments, customized anti-corrosion surface treatment options are available upon request
