MVR42016 Adjustable Injector 1.6 mm | 4060 PSI MV Line

MVR42016 Adjustable Chemical Injector (1.6 mm, 4,060 PSI)

• Adjustable Venturi chemical injector designed for controlled downstream detergent delivery in professional cleaning systems.
• Configured with a 1.6 mm orifice and rated to 4,060 PSI for reliable performance on light- to medium-duty pressure washer platforms.
• Optimized for approximately 2.0–4.5 GPM machines where stable draw and repeatable dilution are required without adding complex valving.
• Built for WSHPWR.com customers who need dependable chemical pickup, quick soap-to-rinse transitions, and service-friendly integration on carts, skids, and fixed wash bays.

Chemical Injection Method

MVR42016 Venturi Draw with Adjustable Control

• Venturi geometry creates a controlled low-pressure zone that pulls detergent through the pickup hose when system backpressure is reduced in chemical mode.
• Integrated metering knob allows fine, repeatable adjustment of chemical concentration to match soil load, surface condition, and detergent instructions.
• 1.6 mm orifice sizing supports consistent pickup on lower-to-mid flow machines, helping maintain stable foam and predictable dwell time.
• Uniform mixing at the injector reduces operator-dependent variation, improving consistency across multiple users and repeated wash cycles.

Tip-Based Switching for Soap and Rinse

• Designed for downstream application where chemical draw is typically engaged with a low-pressure soap nozzle and disabled by switching to a high-pressure rinse tip.
• Supports efficient workflow in the field by reducing the need for separate chemical valves and simplifying operator steps during production cleaning.
• Promotes cleaner rinsing by allowing immediate transition from chemical application to high-pressure rinse without disconnecting the suction circuit.
• Helps protect surfaces by enabling quick reduction in chemical strength when moving from heavy-soil zones to sensitive finishes.

MVR42016 System Integration and Performance

Optimized for 2.0–4.5 GPM Machines

• Matched to systems where injector sizing directly affects draw stability, application uniformity, and overall rinse behavior.
• Maintains dependable suction across typical mobile-rig constraints such as moderate hose lengths, hose reels, and frequent trigger cycling.
• Balanced flow characteristics help avoid excessive restriction that can reduce effective rinse pressure or make downstream tools feel unresponsive.
• Supports repeatable cleaning outcomes when crews need consistent chemical strength from the first pass through the final rinse.

Backflow Protection and Chemical Supply Control

• Integrated check valve prevents reverse flow into the chemical container during shutdown, pressure spikes, or rapid mode changes.
• Helps protect chemical quality by limiting unintended dilution and reducing contamination risk through the suction line.
• Improves response when re-entering chemical mode by reducing flooding of the pickup hose and stabilizing draw sooner.
• Supports safer, cleaner operation by limiting chemical migration when the injector is not actively drawing.

Construction and Durability

Materials for Chemical Exposure

• MVR42016 Brass body provides durability and dimensional stability for daily service in mobile and stationary wash systems.
• Stainless-steel internal components improve resistance to corrosion and wear when used with compatible detergents and degreasers.
• Precision-machined internal bore reduces turbulence and unnecessary energy loss, supporting stable hydraulic behavior.
• Designed to hold performance under vibration, thermal cycling, and frequent connection cycles typical of field equipment.

Compact Inline Form Factor

• Inline design integrates cleanly between downstream components, supporting straightforward plumbing on carts, skids, and wall manifolds.
• Flow-direction marking on the body helps reduce installation errors that can cause weak draw or no chemical pickup.
• Small footprint fits crowded equipment layouts alongside unloaders, gauges, filters, and hose reels without forcing restrictive routing.
• Service-friendly layout keeps the metering control accessible for quick adjustment and routine inspection.

Operation and Maintenance

Best Practices for Consistent Draw

• Use a vented chemical container and place it close to the MVR42016 injector to reduce suction losses and stabilize pickup.
• Keep suction hose runs short, properly sized, and free of kinks, soft spots, or collapse that can reduce draw strength.
• Maintain airtight suction connections; small air leaks can cause intermittent pickup, weak foam, and inconsistent dilution.
• Adjust the metering knob gradually and verify application strength at the nozzle when changing detergents, temperatures, or hose configurations.

Routine Maintenance for Long Service Life

• MVR42016 Flush clean water through the injector and suction line after chemical use to reduce residue buildup and prevent sticking of internal components.
• Inspect and clean the pickup screen regularly to maintain flow into the suction circuit and protect consistent draw.
• Replace hardened or discolored suction tubing as part of preventive maintenance to avoid air leaks and chemical restriction.
• Keep chemical containers and pickup assemblies clean to protect sealing surfaces and maintain predictable performance over time.
