MVR20016 Adjustable Injector 1.6 mm | 4060 PSI Chem

MVR20016 Adjustable Chemical Injector (1.6 mm, 4,060 PSI)

• Adjustable Venturi chemical injector engineered for controlled detergent draw and operator-managed dilution in professional pressure washing systems.
• Configured with a 1.6 mm orifice and rated to 4,060 PSI for commercial equipment where dependable chemical delivery and repeatable tuning are required.
• Designed for approximately 2.0–4.5 GPM systems that need stable suction performance while allowing technicians to fine-tune chemical strength for different surfaces and soils.
• Supports wash programs that change frequently—pre-soak, detergent wash, and rinse—without requiring injector swaps or fixed-ratio limitations.

Chemical Injection Method

MVR20016 Venturi-Based Draw with Adjustable Metering

• Uses a Venturi restriction to create a controlled low-pressure zone that draws detergent into the water stream during low-pressure chemical mode.
• Integrated metering control allows the operator to regulate chemical concentration in real time, improving flexibility across mixed workloads.
• Adjustment capability supports consistent results across varied detergents, including soaps, general-purpose cleaners, and compatible degreasers that behave differently under suction.
• Operator-controlled dosing helps reduce over-application on light soil while maintaining adequate concentration for heavy buildup when required.

Application Control for Job-to-Job Consistency

• Adjustable design supports standardized procedures by allowing crews to set a preferred range for specific tasks and repeat it across service calls.
• Improves process control in environments where multiple surfaces and contamination types are encountered in the same shift.
• Supports predictable wetting and dwell behavior by enabling the operator to match concentration to ambient conditions, surface temperature, and soil load.
• Reduces rework by allowing fast correction if foam is too light, dwell is too short, or chemical strength is excessive for the substrate.

System Integration and Performance

Flow Range Compatibility and Pressure Management

• MVR20016 Optimized for roughly 2.0–4.5 GPM systems where injector sizing influences both suction strength and pressure drop behavior.
• Designed to minimize unnecessary pressure loss so the system maintains usable performance during rinse cycles and transitions cleanly between soap and high-pressure operation.
• Best performance is achieved when installed in the correct location in the discharge circuit and paired with low-pressure soap tips that enable stable Venturi suction.
• Stable draw characteristics support longer hose runs and common field configurations, including hose reels and frequent trigger cycling.

Backflow Protection and Chemical Line Control

• MVR20016 Integrated check valve prevents reverse flow into the chemical line, protecting detergent containers from contamination and unintended dilution.
• Reduces the risk of chemical container pressurization during shutdown or rapid pressure changes.
• Helps maintain prime and responsiveness when switching back into chemical mode after rinsing.
• Supports cleaner operation by reducing migration of water into the suction hose when the injector is not actively drawing.

Construction and Durability

Materials Selected for Chemical Exposure

• Corrosion-resistant brass body provides durability for daily handling, vibration, and continuous-duty service.
• Stainless-steel internal components resist wear and corrosion in detergent environments common to professional cleaning programs.
• Precision-machined internal passages reduce turbulence and support efficient hydraulic behavior, helping preserve pump efficiency.
• Compact inline form factor supports clean integration on skids and carts without requiring excessive plumbing complexity.

Installation Details That Reduce Errors

• Inline body is intended to install downstream of the pump in the discharge circuit where chemical injection is typically managed during low-pressure operation.
• Flow-direction marking supports correct orientation, reducing troubleshooting time associated with reversed installation.
• Standard threaded or quick-connect compatibility supports rapid service replacement and consistent fleet builds.
• Compact design fits crowded manifolds and tight frame rails while maintaining reasonable access for adjustment.

Operation and Maintenance

Operating Practices for Stable Draw

• MVR20016 Chemical draw is typically engaged using a low-pressure soap nozzle; switching to a high-pressure tip generally stops draw by increasing backpressure.
• Best results are achieved when the detergent container is vented, positioned close to the injector, and connected with an unrestricted suction hose.
• Stable draw depends on airtight suction connections, a clean strainer, and eliminating kinks or restrictions that reduce suction flow.
• Metering adjustments should be made gradually to maintain consistent foam and predictable dwell, especially when changing detergent types.

Routine Maintenance Guidelines

• MVR20016 Flush clean water through the injector and suction line after detergent use to prevent residue buildup and check-valve sticking.
• Inspect the intake screen, suction tubing, and fittings routinely for debris, softening, or air leaks that can interrupt draw.
• Keep chemical containers free of sediment to protect internal sealing surfaces and maintain consistent performance.
• Replace worn suction components proactively in high-use environments to maintain repeatability and minimize downtime.
