VRT3-160 | 2400 PSI Unloader Valve Yellow Spring Control Valve

VRT3-160 – Unloader Valve – 2,320 PSI – 3/8″ NPT F-F

The VRT3-160 unloader valve is a professional pressure-washer regulator engineered for
stable control at 2,320 PSI (160 bar). Tuned with a yellow spring for precise, repeatable
adjustment, it diverts flow to bypass the instant the trigger is released—protecting pumps, hoses, guns,
and accessories from damaging pressure spikes and heat buildup. With
3/8″ NPT female ports and a rugged, service-friendly body, the VRT3-160 installs
cleanly on contractor and light-industrial systems for dependable, day-to-day performance.

What This Means for Your Rig

If your crews run mid-pressure equipment all day, a correctly sized unloader is the backbone of safety and
consistency. The VRT3-160’s yellow-spring class holds output steady across changing tips
and hose lengths, reducing chatter, hose whip, and seal wear so operators get a smoother, more predictable
wash and you see fewer avoidable downtime events.

Performance Specs (Quick Reference)

• Max Pressure: 2,320 PSI (160 bar)
• Flow Capacity: Match to pump GPM for best performance
• Temperature: Up to 194 °F (90 °C) typical; confirm seal kit for hot-water or chemical use
• Connections / Ports: Inlet, Outlet, Bypass – 3/8″ NPT female (National Pipe Thread, US)
• Spring / Control: Yellow spring; adjustable regulation for the 160-bar class
• Function: Trapped-pressure unloader; automatic bypass when trigger is released

Build & Materials (Made to Last)

• Reinforced housing with precision-engineered internals for smooth modulation.
• Metal NPT-female ports for repeatable torque and leak-resistant sealing.
• Clear port layout for tidy routing to gauge tees, hose reels, and return-to-tank lines.
• Common VRT3 wear parts for predictable, fast maintenance.

Benefits & Differentiators (Why Choose This Model)

• Stable 160-bar regulation for uniform cleaning results.
• Smooth bypass behavior reduces pressure spikes, heat, and water hammer.
• Service-friendly design with straightforward adjustments and familiar parts.
• Clean US-standard plumbing with 3/8″ NPT-female ports.
• Consistent operator feel across tips and hose lengths to shorten training time.

Industries & Applications

• Contractor cleaning systems and mobile wash rigs.
• Light-industrial maintenance and facility wash bays.
• Commercial property services and fleet wash stations.
• Municipal / public works equipment washdown.
• Agriculture and food equipment washdown (where chemical compatibility is verified).

Compatibility & Fit (Mounting, Plumbing, Nozzles)

• Install downstream of the pump and upstream of hose or reel; route bypass back to tank when recirculation is required.
• Use thread sealants approved for high-pressure water and verify torque on metal fittings.
• Pair with triplex pumps configured for working pressures up to 2,320 PSI; include thermal relief,
  inlet filtration, a test-gauge tee, and burst-rated hose/wand assemblies.
• Nozzle / orifice guidance: select a spray-tip orifice that matches pump GPM at target PSI;
  adjust pressure with flow present (trigger open), then secure the setting.

Setup, Service & Reliability

• Prime with clean water, purge air, and verify supply before first start.
• Adjust pressure only with the trigger pulled to avoid false readings and over-pressure.
• Inspect inlet screens regularly; watch for chatter or creeping pressure as indicators of wear or contamination.
• Service on a preventive schedule using the appropriate VRT3 wear parts; keep temperature, water quality,
  and chemistry within manufacturer limits.
