MVR42023 Adjustable Injector 2.3 mm | 4060 PSI MV Line

MVR42023 Adjustable Chemical Injector (2.3 mm, 4,060 PSI)

• Adjustable Venturi chemical injector engineered for high-output downstream detergent delivery in professional pressure washer systems.
• Configured with a 2.3 mm orifice and rated to 4,060 PSI for strong, steady chemical pickup in demanding wash programs.
• Matched to approximately 3.5–6.5 GPM machines where higher flow and longer hose layouts require robust suction.
• Ideal for mobile trailers, skid builds, and fixed wash bays that need fast soap-to-rinse changeovers with repeatable chemistry control.

Chemical Injection Performance

Venturi Suction with On-the-Fly Metering

• Venturi throat creates a low-pressure region that draws detergent through the pickup hose when backpressure is reduced in soap mode.
• 2.3 mm orifice supports higher-flow rigs by sustaining strong draw characteristics without unstable surging.
• MVR42023 integrated metering knob provides smooth, repeatable adjustment of chemical concentration for light film removal through heavy degreasing.
• Stable draw helps maintain consistent foam and wetting across long hose runs, reels, and frequent trigger cycling.

Backflow Protection for Cleaner Operation

• Built-in check valve prevents back-feeding into the chemical container during shutdowns, pressure spikes, or rapid mode changes.
• Helps protect detergent quality by reducing unintended dilution and contamination through the suction line.
• Minimizes line flooding and improves response time when switching back into soap mode.
• Supports cleaner, more predictable operation on multi-operator rigs and busy wash lanes.

Construction and Integration

Durable Materials for Chemical Environments

• Rugged brass body provides strength and corrosion resistance for daily use in mobile and stationary wash systems.
• Stainless-steel internal components improve longevity when used with compatible soaps, detergents, and degreasers.
• Precision-machined flow path reduces turbulence and unnecessary restriction to preserve system efficiency.
• Designed to withstand vibration, thermal cycling, and frequent connect/disconnect routines in field service conditions.

MVR42023 Adjustable Injector 2.3 mm | 4060 PSI MV Line Compact Inline Design

• Inline profile integrates cleanly on skids and carts where space is limited and plumbing routes must stay efficient.
• Installs downstream of the pump/unloader so it can operate as a true downstream injector for tip-based soap/rinse switching.
• Directional marking on the body reduces installation errors that commonly cause weak draw or no draw.
• Fits neatly among filters, gauges, unloaders, and manifolds without forcing restrictive hose bends.

Operation and Maintenance

How It Operates in the Field

• Tip-driven behavior: low-pressure soap nozzle typically engages chemical draw, while switching to a high-pressure tip stops injection for rinse.
• Metering knob MVR42023 allows crews to standardize dilution settings for recurring jobs and quickly adjust for heavier soil conditions.
• Best performance comes from a vented detergent container, short pickup runs, and airtight suction connections.
• Designed to maintain dependable suction on long hose runs and complex routing common to trailers and wash lanes.

Routine Care to Keep Draw Strong

• Flush clean water through the injector and pickup hose after chemical use to prevent residue, scaling, and sticky check valve behavior.
• Inspect and clean the intake screen regularly to avoid restriction that reduces draw and foam consistency.
• Replace aged or hardened pickup tubing to prevent micro air leaks that cause intermittent suction and inconsistent ratios.
• Store clean and dry when possible to extend service life and maintain predictable performance.
