VRT100R-350 | 5100 PSI 1/2 in Regulating Valve Pump Control

VRT100R-350 | 5100 PSI 1/2 in Regulating Valve Pump Control

• The VRT100R-350 is a high-pressure regulating valve designed for
  precise, real-time pressure control at 5,075 PSI (350 bar) in
  professional pressure washer systems.
• Built for on-the-fly adjustment without shutting down equipment,
  this blue-spring regulator maintains a steady working setpoint and
  diverts excess flow to bypass to protect pumps, hoses, guns, and
  accessories.
• Features 1/2 in NPT female inlet and outlet ports for clean
  integration into commercial and industrial rigs that demand stable pressure,
  fast tuning, and long service life.

What This Means for Your Rig

• Provides consistent ≈5,100 PSI performance across changing tips,
  wands, and hose lengths, reducing hunting and pressure drift.
• Real-time adjustment lets crews fine-tune pressure for different
  nozzles or tasks without stopping the machine or depressurizing the system.
• Controlled bypass flow helps limit heat buildup and cavitation risk
  in continuous-duty applications.
• Reduces operator fatigue by cutting pressure fluctuation, chatter, and hose whip,
  while protecting high-value pump components from stress.

Performance Specs VRT100R-350 (Quick Reference)

• Max Pressure: 5,075 PSI (350 bar)
• Flow Capacity: Match to pump GPM for best results
  (commercial high-flow class).
• Temperature: Up to 194°F (90°C) typical; confirm
  seal kit for hot-water and chemical applications.
• Connections / Ports:
  • Inlet: 1/2 in NPT female
  • Outlet: 1/2 in NPT female
  • Bypass return: dedicated port (verify thread on your kit)
• Control Type: Pressure regulator that maintains a set pressure and
  routes excess flow to bypass.
• Spring / Adjustment: Blue spring for high-pressure stability with
  tool-assisted fine tuning.

Build & Materials VRT100R-350 (Made to Last)

• Corrosion-resistant body engineered for wet, chemical, and outdoor
  environments typical of commercial wash bays and industrial plants.
• Precision-machined internals deliver smooth modulation with minimal
  pressure oscillation under vibration and frequent cycling.
• Metal 1/2 in NPT-female ports support repeatable torque and
  leak-resistant sealing with approved thread sealants.
• Serviceable wear components make it easy for shop techs and field
  crews to maintain performance over the life of the system.
• Clear and logical port layout simplifies routing to
  gauge tees, hose reels, and bypass return-to-tank lines.

Benefits & Differentiators VRT100R-350 (Why Choose This Model)

• Stable 5,075-PSI setpoint for uniform cleaning results across
  different operators and accessories.
• On-the-fly pressure adjustment without shutting down equipment,
  boosting productivity on multi-step cleaning jobs.
• Cooler pump operation by bypassing only excess flow instead of
  cycling the entire volume.
• US-standard plumbing: 1/2 in NPT-F inlet/outlet integrates easily
  into North American systems and fittings.
• Reduced operator fatigue thanks to lower pressure chatter, less
  hunting, and a more predictable trigger feel.
• Predictable maintenance with common, readily available regulator
  wear parts.

Industries & Applications

• Industrial pressure washers and plant wash bays
• Commercial facilities and maintenance crews
• Contractor rigs and mobile wash fleets
• Municipal / public works equipment washdown
• Construction and heavy equipment cleaning
• Agriculture and food equipment washdown (with verified chemical and
  seal compatibility)

Compatibility & Fit (Mounting / Plumbing / Nozzles)

• Plumbing & orientation: Install downstream of the pump and
  upstream of the hose/reel. Route the bypass return to tank or a cooling /
  recirculation loop per your system design.
• Use thread sealants rated for high-pressure water service and
  verify torque on all metal fittings to maintain leak-free operation.
• Porting standard: Inlet 1/2 in NPT-F; Outlet 1/2 in NPT-F; dedicated
  bypass return port (confirm thread type on your specific kit).
• Power pairing: Ideal with triplex pumps operating
  up to 5,075 PSI; include thermal relief, inlet filtration, a regulator gauge tee,
  and burst-rated hose/wand assemblies.
• Nozzle / orifice guidance:
  • Size the spray tip orifice to match pump GPM at your target PSI; correct sizing
    is critical for steady regulation.
  • With flow present (trigger open), set the working pressure, then lock the
    adjustment per your SOP.

Setup, Service & Reliability

• Startup: Prime with clean water, purge air, and verify inlet
  supply before first start.
• Adjustment: Adjust pressure only with the trigger pulled to avoid
  false readings and unintended over-pressure.
• Inspection: Check inlet screens and strainers regularly; creeping
  pressure or chatter can indicate wear, contamination, or mis-sizing.
• Preventive service: Maintain on a set schedule using the correct
  regulator wear parts for your duty cycle.
• Operating limits: Keep temperature, water quality, and chemistry
  within manufacturer limits to maximize seal life and efficiency.

What’s Included

• VRT100R-350 regulating valve (blue-spring, high-pressure class).
• Ports: Inlet 1/2 in NPT-F, Outlet 1/2 in NPT-F, plus dedicated
  bypass return.
• Basic installation and setup guidance from the manufacturer or
  distributor.

VRT100R-350 | 5100 PSI 1/2 in Regulating Valve Pump Control

• This is a regulating valve that maintains pressure and bypasses
  excess flow; it is not a trapped-pressure unloader.
• If your system uses BSPP/BSPT or quick-connects, list any
  included adapters on your product page so installers can match threads on the
  first visit.
