MV60V | Vertical Flow Switch, 4350 PSI Pump Control

MV60V

4,350 PSI vertical flow switch with automatic pump control

• The AR MV60V is a high-pressure vertical flow switch that detects water
  movement in a vertical line and automatically starts or stops the pump based on real flow.
• Rated to 4,350 PSI, it protects pumps, hoses, seals, and motors from dry-run, cavitation,
  overheating, and damaging pressure spikes.
• Purpose-built for vertical risers where space is tight or plumbing feeds up to reels and manifolds, providing
  dependable, hands-free system control across long shifts and mixed-duty cycles.

Construction & Materials

Brass body with stainless-steel internal components

• Rugged, corrosion-resistant brass body sheds heat efficiently and withstands harsh
  wash-bay and industrial environments.
• Stainless-steel internals and precision sealing elements resist scaling, chemical attack,
  and wear from high-pressure operation.
• Compact housing with NPT-style threaded connections threads neatly into vertical risers,
  discharge lines, or manifolds without crowding adjacent components.
• Low-restriction internal geometry preserves system efficiency and minimizes pressure drop while maintaining
  reliable sensitivity to flow changes.

MV60V How It Works

Flow-based sensing for start/stop control

• When a downstream trigger gun, valve, or zone opens and water begins to move, an internal piston and magnetic
  actuator travel to close the control circuit and start the pump.
• When the tool closes or a fault interrupts flow, the sensing assembly returns instantly, opening the
  circuit and shutting the pump down to prevent heat buildup and seal wear.
• Because actuation is tied to actual flow rather than pressure alone, the MV60V continues to
  protect the system during conditions such as clogged nozzles, collapsed supply hoses, air ingestion, or
  unexpected valve closures.
• Rapid response shields downstream accessories and high-pressure hoses from shock loads and transient spikes.

Protection & System Benefits

Safety, efficiency, and extended equipment life

• Prevents dry-running and cavitation by ensuring the pump runs only when adequate flow is
  present.
• Reduces overheating and premature seal, hose, and fitting failures by automatically stopping the pump during
  idle moments.
• Improves energy efficiency and stabilizes maintenance schedules by eliminating unnecessary run time and
  limiting exposure to pressure transients.
• Gives operators confidence that the system will shut down safely if a hose fails, a nozzle plugs, or a supply
  line starves the pump.

Installation & Integration

Vertical mounting with flexible control wiring

• Designed specifically for true vertical runs; installs in vertical risers or discharge lines
  close to pumps, unloaders, or distribution headers.
• Uses standard threaded fittings for quick retrofit into existing high-pressure plumbing.
• Sealed electrical interface connects easily to pump contactors, PLC inputs, safety interlocks, or automation
  panels.
• Can be wired for normally open or normally closed logic to match system design and control
  philosophy.
• For commissioning, mount in the correct orientation, follow flow-direction markings, route conductors away
  from heat sources, and verify start/stop operation by cycling the downstream gun or valve.

Maintenance & Best Practices

Minimal service for long-term reliability

• Periodically confirm tight, corrosion-free electrical connections and check for external leaks around
  threaded joints.
• Ensure upstream filtration keeps fines and sediment from accumulating in the flow chamber to maintain crisp
  actuation.
• MV60V Flush with fresh water on systems that routinely handle reclaimed or sediment-bearing water to prevent
  sticking and scale buildup.
• Include functional tests—verifying that the pump stops when flow ceases—as part of routine safety and
  preventive maintenance checks.

Typical Applications

Vertical-line monitoring in demanding systems

• Industrial and commercial pressure washer skids and trailer rigs.
• Automated and manual wash bays with vertical risers feeding hose reels or manifolds.
• Hydrostatic check and test stands requiring flow-confirmed pump control.
• Plant washdown systems and multi-zone cleaning installations.
• Any high-pressure system where flow-verified, automatic pump shutoff is critical for safety and longevity.
