VRT100-190D | 2800 PSI 1/2 NPT Unloader Valve Yellow Spring Control

VRT100-190D – Unloader Valve – 2800 PSI – 1/2″ NPT – Yellow Spring

The VRT100-190D unloader valve is a durable, contractor-grade regulator built for stable pressure control at
2,800 PSI (190 bar). Equipped with a reinforced yellow spring for precise, repeatable adjustments, it automatically
diverts flow to bypass the moment the trigger is released—protecting pumps, hoses, guns, and accessories from
harmful pressure spikes and heat buildup.

Standard 1/2″ NPT female ports allow fast, straightforward integration into carts, skids, trailers, and fixed wash bays.
The D-series design focuses on rugged materials, service-friendly access, and long service life with minimal downtime.

What This Means for Your Rig

For teams running mid-to-high pressure daily, a properly sized unloader is the backbone of reliability and safety.
The VRT100-190D’s yellow spring maintains stable pressure across changing nozzles, hose lengths, and flow conditions—reducing chatter, hose whip, and premature seal wear.

• Smoother, more predictable washing performance.
• Lower operator fatigue and easier training.
• Reduced maintenance issues across your fleet.

Performance Specs VRT100-190D (Quick Reference)

• Max Pressure: 2,800 PSI (190 bar)
• Flow Capacity: Match to pump GPM (VRT100 series supports commercial flows)
• Temperature Rating: Up to 194°F (90°C) typical
• Connections: Inlet / Outlet / Bypass – 1/2″ NPT female
• Spring: Reinforced yellow spring with adjustable regulation
• Function: Trapped-pressure unloader; auto-bypass on trigger release

Build & Materials (Made to Last)

A reinforced body, precision valve stack, and robust spring deliver repeatable performance even under vibration,
frequent cycling, and heavy daily use. Metal NPT ports offer reliable torque handling and leak-resistant sealing.

• Clear port layout simplifies plumbing to reels, gauges, or return-to-tank lines.
• Common wear parts allow quick preventive maintenance.
• Service-friendly access reduces downtime for shop and field teams.

Benefits & Differentiators

• Stable regulation for 190-bar systems with uniform cleaning results.
• Smooth bypass activation that reduces heat, oscillation, and water hammer.
• Familiar wear parts and simple adjustments keep service costs low.
• 1/2″ NPT ports provide clean, standard plumbing throughout U.S. systems.
• Fleet consistency—standardize multiple rigs with predictable performance.

Industries & Applications

• Mobile contractor wash fleets
• Facility maintenance and commercial washers
• Industrial wash bays and manufacturing plants
• Municipal and public works washdown
• Construction and rental yard equipment cleaning
• Agriculture and food-service washdown (chemistry-verified)

Compatibility & Fit

• Plumbing & Orientation: Install downstream of the pump. Route bypass to tank if required by your system.
• Port Standard: All ports are 1/2″ NPT female. Rated adapters required for BSP or quick-connect systems.
• Power Pairing: Ideal for triplex pumps up to 2,800 PSI; pair with thermal relief, filtration, and burst-rated hose.
• Nozzle / Orifice Guidance:
  • Select a nozzle that matches pump GPM at target PSI.
  • Adjust pressure only with trigger open to ensure accurate readings.
  • Turbo nozzles cause momentary spikes—verify all components are properly rated.
• Recommended Accessories: Gauge tee, inlet screen, thermal relief valve, rated high-pressure hose.

Setup, Service & Reliability

• Prime system, purge air, and verify water supply before startup.
• Adjust only with the trigger pulled—prevents false readings.
• Monitor for chatter, pressure creep, or heat as early warning signs.
• Service with correct VRT100 wear parts on a preventive schedule.
• Keep chemistry, water quality, and temperature within specification for maximum seal life.
