VRT3-310EZ | 4500 PSI Unloader Valve EZ Start Feature Valve

VRT3-310EZ | 4500 PSI Unloader Valve EZ Start Feature Valve

• The VRT3-310EZ unloader valve brings EZ Start convenience to the proven VRT3 platform, delivering
  stable regulation in the 310 bar (≈4,500 PSI) class at flows up to 10.5 GPM.
• During ignition, EZ Start temporarily lowers system pressure so engines and motors come to speed with less strain,
  helping protect pump seals, couplers, and drive components.
• In operation, the valve automatically diverts flow to bypass the instant the trigger is released, minimizing heat,
  chatter, and water hammer so operators get consistent working pressure across long hose runs and varied spray tips.

What This Means for Your Rig

• For high-pressure contractor or industrial machines that run all day, smoother startups mean fewer trip-outs,
  less operator fatigue, and longer service intervals.
• The VRT3-310EZ’s black-spring class provides the headroom needed for turbo nozzles and demanding tools.
• Predictable bypass behavior keeps output steady and protects downstream accessories, delivering
  uptime you can count on and a uniform feel across multiple rigs and bays.

Performance Specs (Quick Reference)

• Max Pressure: 310 bar (approximately 4,500 PSI)
• Max Flow: up to 10.5 GPM
• Temperature: up to 194°F (90°C) typical for VRT3 class (confirm seal selection for hot chemical use)
• Connections / Ports: Inlet, Outlet, Bypass – 3/8 in NPT female (National Pipe Thread, US)
• Control: adjustable regulation with high-pressure black spring; EZ Start assists during ignition
• Typical Use: trapped-pressure unloader for commercial cold- or hot-water systems

Build & Materials (Made to Last)

• Reinforced VRT3 body, precision valve stack, and metal threaded ports are engineered for repeatable torque and
  long service life under vibration and continuous cycling.
• Compact form factor fits neatly into skids, enclosed carts, and wall-mount bays.
• Standardized port locations support clean plumbing with gauge tees, hose reels, and return-to-tank layouts.
• Shared VRT3 wear parts and established service procedures keep maintenance predictable and cost-effective across fleets.

Benefits & Differentiators (Why Choose This Model)

• EZ Start technology: lowers startup load so engines and motors reach speed smoothly.
• High-pressure stability: black spring maintains set pressure in the 4,500 PSI class.
• Smooth bypass behavior: reduces pressure spikes, heat buildup, hose whip, and seal wear during trigger cycling.
• Faster training & setup: predictable, repeatable adjustments across multiple rigs.
• Service friendly: common VRT3 wear parts and familiar repair workflows.
• Clean installs: standardized NPT-female ports simplify fittings and reduce leak points.

Industries & Applications

• Industrial contractors and mobile wash fleets
• Facility and plant wash bays
• Commercial fleets and rental yards
• Municipal and public works equipment washdown
• Construction and heavy equipment cleaning
• Agriculture and food equipment washdown (with verified chemical compatibility)

Compatibility & Fit VRT3-310EZ (Mounting, Plumbing, Nozzles)

• Plumbing & orientation: install downstream of the pump and upstream of hose or reel. Route bypass back to tank
  when your system requires recirculation.
• Use thread sealants approved for high-pressure water service and verify torque on metal fittings for leak-free operation.
• Porting standard: Inlet, Outlet, Bypass are 3/8 in NPT female (National Pipe Thread, US). If adapting to BSP or other
  thread standards, use rated adapters and confirm sealing surfaces and flow path.
• Power pairing: ideal for triplex pumps delivering up to 10.5 GPM in the 4,000 to 4,500 PSI range on gas-engine or
  electric builds.
• Include a thermal relief valve, inlet filtration, regulator and gauge, and burst-rated hose and wand assemblies
  for a complete system.
• Nozzle & orifice guidance:
  • Select a spray tip orifice that matches pump GPM at the target PSI; correct orifice is essential for stable pressure and unloader performance.
  • With water flowing (trigger open), adjust to reach working pressure, then secure the setting per your SOP.
  • Turbo nozzles can create momentary spikes; ensure every component, including the unloader, is rated at or above system pressure with margin.

Setup, Service & Reliability

• Prime with clean water, purge air, and confirm supply flow before first start to prevent cavitation and false readings.
• Adjust pressure only with the trigger pulled to avoid false readings and over-pressure.
• Inspect inlet screens regularly and monitor for chatter or creeping pressure as indicators of wear or contamination.
• Verify EZ Start behavior during commissioning, then add the check to your preventive maintenance routine.
• Keep temperature, chemical exposure, and water quality within manufacturer limits to maximize seal life and efficiency.
