MV20016 Chemical Injector 1.6 mm | 4060 PSI Fixed Chem

MV20016 Fixed Chemical Injector

Overview

The AR MV20016 fixed chemical injector is a precision-engineered Venturi mixing device designed to deliver accurate, repeatable detergent ratios for professional pressure washing and industrial cleaning systems operating at high duty cycles. Built around a 1.6 mm orifice and rated to 4,060 PSI, it provides strong suction, reliable chemical delivery, and stable system performance without requiring metering pumps, electrical components, or manual calibration.

How the Injector Works

• Venturi Action – Accelerates water through a precision-machined bore to create a controlled low-pressure zone.
• Chemical Draw – The low-pressure zone pulls detergent through the suction barb and integrated check valve.
• Smooth Mixing – Produces a uniform, foam-friendly solution without air ingestion or flow pulsation.
• Fixed Ratio – Ensures consistent dilution across minor pressure fluctuations and operator changes.

Construction & Durability

• Brass Body – Corrosion-resistant and designed for long-term industrial use.
• Stainless-Steel Internal Components – Spring, valve, and internal parts resist chemical attack and vibration fatigue.
• Laminar-Flow Geometry – Minimizes turbulence, pressure drop, and orifice clogging.
• One-Piece Compact Design – Reduces leak points and simplifies installation.

Performance Specifications

• Orifice Size: 1.6 mm
• Operating Flow: Ideal at approx. 2.0–4.5 GPM (usable up to 5.0 GPM in favorable conditions)
• Max Pressure: 4,060 PSI
• Operation: Fixed-ratio downstream injection
• Function: Automatic soap/rinse switching with low- and high-pressure nozzles
• Materials: Brass body, stainless internal components

System Compatibility

• Supports hot- or cold-water systems within rated temperature limits.
• Maintains suction under vibration, thermal expansion, and variable inlet conditions.
• Compatible with foam lances, downstream brushes, and long hose runs.

Installation of MV20016

• Install in the discharge line between the pump/unloader and the gun/wand.
• Align flow with the marked direction on the injector.
• Use standard threaded or quick-connect couplers.
• Engage a low-pressure nozzle to activate chemical draw.
• Switch to a high-pressure nozzle to stop draw for full-power rinsing.

Integrated Check Valve

• Prevents water from back-feeding into the detergent container.
• Maintains chemical purity and protects internal components.
• Ensures immediate suction when switching to a low-pressure tip.

Applications

• Fleet depots and wash bays
• Heavy equipment and vehicle maintenance
• Manufacturing facilities and shop floors
• Agricultural equipment washing
• Exterior building cleaning and industrial washdown
• Roll-off containers and material-handling gear

Maintenance

• Flush clean water MV20016 for 1–2 minutes after chemical use to prevent scale and residue.
• Inspect and clean the suction barb and filter periodically.
• Ensure detergent container is vented for proper siphon function.
• Check suction line for kinks or air leaks.

Troubleshooting

• Weak chemical draw: Incorrect nozzle (not low-pressure), clogged filter/orifice, kinked hose, air leak, or unvented detergent container.
• Pulsing mixture: Air intrusion at fittings or excessive restriction in the suction hose.
• Residual soap during rinse: Worn high-pressure tip or debris preventing full check-valve closure.

Best-Practice Setup

• Use chemical-rated suction hose with an inline screen filter.
• Keep detergent container positioned to avoid siphon interruption.
• Select correct low-pressure tips for soap and properly sized high-pressure tips for rinse.
• Avoid tight bends, undersized tubing, or flow restrictions.

Key Benefits

• Consistent, repeatable dilution ratios
• Durable brass and stainless-steel construction
• No calibration drift or adjustment needed
• Low maintenance and long service life
• Improved chemical efficiency and reduced waste

MV20016

When integrated into a well-maintained pressure washer system, the AR MV20016 delivers the uniform, maintenance-light detergent injection professionals require. Its fixed-ratio operation, durable construction, and automatic soap/rinse switching make it ideal for industrial environments where consistency, efficiency, and system protection are critical.
