MVR41016 Adjustable Injector 1.6 mm | 4060 PSI

MVR41016 Adjustable Injector 1.6 mm | 4060 PSI MV Line

Adjustable Venturi chemical injector for pro wash systems

• The AR MVR41016 Adjustable Chemical Injector is a precision Venturi metering
  device designed for accurate detergent mixing in professional high-pressure wash systems.
• Features a calibrated 1.6 mm orifice rated up to 4,060 PSI,
  optimized for machines producing approximately 2.0–4.5 GPM.
• Provides fine, on-the-fly control of detergent draw while maintaining stable system pressure
  and responsive downstream accessories.

Venturi Mixing & Metering

Stable suction and adjustable chemical ratio

• High-velocity water accelerates through the 1.6 mm orifice, creating a controlled low-pressure
  zone that pulls detergent through the pickup hose.
• Detergent solution blends directly into the main flow so chemical reaches the gun at a
  stable, repeatable concentration.
• Integrated metering knob provides smooth, incremental adjustment of draw
  rate without tools, allowing tuning to soil load, surface type, and detergent guidelines.
• Venturi action engages chemical draw automatically with a low-pressure soap nozzle and
  disengages when a high-pressure tip is installed, enabling fast soap/rinse transitions.

Construction & Flow Behavior

Brass body with stainless internals

• Built from corrosion-resistant brass with stainless-steel internal
  components to resist chemical attack, thread wear, and vibration fatigue.
• Precision-machined internal geometry minimizes turbulence and unnecessary pressure loss,
  preserving overall system efficiency.
• Maintains steady chemical draw over long hose runs and varying operating
  conditions without starving the pump.
• Suitable for both hot- and cold-water operation within rated temperature limits.

Check Valve Protection

Clean, one-way chemical flow

• Integrated check valve prevents backflow into the detergent container during
  pressure fluctuations or shutdown.
• Protects chemical product from contamination and keeps the pickup line clean and dry between
  uses.
• Reduces risk of cross-mixing when multiple detergents or tanks are used on the same rig.

Installation & Setup

Downstream mounting for reliable performance

• Install the injector downstream of the pump (typically after the unloader)
  using standard threaded or quick-connect fittings.
• Observe the flow-direction arrow on the body to ensure correct orientation.
• Route the suction line to a vented detergent container and fit a clean intake
  screen to keep debris out of the metering passage.
• Position the container close to the injector to reduce lift and stabilize chemical draw.

Operation & Best Practices

Dial-in control and consistent results

• Pair with properly sized low-pressure soap tips to keep the Venturi in its ideal
  operating window.
• Record preferred metering knob settings for common jobs so crews can return to proven ratios
  quickly.
• Check suction connections for airtight seals to prevent entrained air that can weaken draw and
  cause inconsistent application.
• Use high-pressure tips for rinse; switching tips automatically stops chemical draw without
  extra valves or plumbing.

Maintenance

Simple service for long injector life

• After detergent use, flush clean water through the injector to clear the pickup
  hose and metering circuit.
• Inspect and rinse the intake screen regularly; replace aged or hardened suction tubing to keep
  flow unrestricted.
• Periodically verify fittings and threads for leaks and re-tighten as needed to maintain
  reliable suction and sealing.

Benefits for Operations

Chemical savings and equipment protection

• Adjustable metering lets teams set concentration only as high as needed, helping to
  reduce chemical spend.
• Uniform, predictable coverage minimizes rework from under- or over-soaping on vehicles,
  equipment, and masonry.
• Downstream injection limits unnecessary high-pressure exposure during the soap stage, helping
  extend hose, seal, and accessory life.
• Compact profile fits easily on carts, skids, and wall systems while leaving service access for
  quick checks and changeovers.

Typical Applications

Where the MVR41016 excels

• Detailing bays and automotive/fleet washing operations.
• Light industrial maintenance and plant washdown.
• Agricultural outbuildings and equipment cleaning.
• Small commercial properties, storefronts, and maintenance contracts.
