VRT3R-310 | High-Pressure Regulator Valve 10.5 GPM 4500 PSI

VRT3R-310 | High-Pressure Regulator Valve 10.5 GPM 4500 PSI

The VRT3R-310 regulator valve is a heavy-duty pressure control solution engineered to stabilize system pressure at 4,500 PSI (310 bar) with flows up to 10.5 GPM. Unlike a trapped-pressure unloader, this adjustable regulator maintains a steady working setpoint and diverts only excess flow to bypass, helping pumps run cooler and more efficiently during long duty cycles. With dual 3/8 in NPT female inlets and dual 3/8 in NPT female bypass ports, it supports flexible plumbing in carts, skids, and fixed wash bays. Built from corrosion-resistant materials with precision-machined internals, the VRT3R-310 delivers smooth control, consistent performance, and long service life in demanding industrial and commercial environments.

What This Means for Your Rig

When your operation requires a stable 4,500 PSI output across different nozzle sizes, hose lengths, and tools, a regulator keeps pressure locked on target without cycling or “hunting.” Dual inlets simplify gauge tees and filter placement, while dual bypass ports make routing excess flow to tank or into a cooling loop easy for continuous-duty applications.

Performance Specs (Quick Reference)

• Max Pressure: 4,500 PSI (310 bar)
• Flow Capacity: up to 10.5 GPM
• Temperature: up to 194°F (90°C), verify seal set for hot-chemical applications
• Connections / Ports: Inlet (x2) 3/8 in NPT female; Bypass (x2) 3/8 in NPT female; Outlet 3/8 in NPT female
• Control Type: pressure regulator (maintains set pressure and sends excess flow to bypass)
• Typical Use: industrial/commercial cold- or hot-water systems needing steady, repeatable pressure

Build & Materials VRT3R-310 (Made to Last)

The corrosion-resistant housing and precision valve stack ensure smooth modulation with minimal pressure oscillation. Metal NPT-female ports allow repeatable torque and leak-resistant sealing. The internal geometry and high-pressure spring are tuned for the 310-bar class, maintaining calibration under vibration and frequent cycling. A clear port layout and serviceable design make preventive maintenance fast and predictable.

Benefits & Differentiators VRT3R-310 (Why Choose This Model)

• Stable 4,500 PSI set pressure for uniform cleaning power
• Cooler pump operation by bypassing only excess flow
• Flexible plumbing with dual inlets and dual bypass ports
• Reduced chatter and drift for improved operator comfort
• Predictable maintenance using common wear parts
• 3/8 in NPT-female ports fit common US fittings and accessories

Industries & Applications

• Industrial pressure washers and plant wash bays
• Commercial cleaning systems and maintenance crews
• Fleet, bus, and heavy equipment wash facilities
• Municipal and public works washdown
• Construction and rental yard equipment cleaning
• Agriculture and food equipment washdown (verify chemical compatibility)

Compatibility & Fit (Mounting / Plumbing / Nozzles)

• Plumbing & orientation: install downstream of the pump and upstream of hose or reel. Route bypass ports to tank or a cooling/recirculation loop. Use high-pressure-rated sealants and verify torque.
• Porting standard: Inlet (x2), Bypass (x2), Outlet — all 3/8 in NPT female.
• Power pairing: ideal with triplex pumps up to 10.5 GPM at ≤4,500 PSI. Include thermal relief, inlet filtration, a gauge tee, and burst-rated hose/wand assemblies.

Nozzle / Orifice Guidance

• Select a spray tip sized for pump GPM at the target PSI; correct orifice is critical for stable regulation.
• Set working pressure only with flow present (trigger open), then lock the adjustment.

Recommended Accessories

• High-pressure hose rated at or above system PSI
• Thermal relief valve
• Inlet filter or screen
• Pressure gauge tee
• Return-to-tank plumbing hardware

Setup, Service & Reliability

• Prime with clean water, purge air, and verify supply before startup.
• Adjust pressure only with the trigger pulled to avoid inaccurate readings.
• Inspect inlet screens regularly; watch for creeping pressure or chatter as signs of wear or contamination.
• Service using the correct regulator wear parts on a preventive schedule.
• Maintain proper water quality, temperature, and chemistry to extend seal life.

VRT3R-310 | High-Pressure Regulator Valve 10.5 GPM 4500 PSI

• This model is a pressure regulator (maintains pressure, bypasses excess flow), not a trapped-pressure unloader.
• If your system uses BSPP/BSPT or quick-connect fittings, ensure proper adapters are installed. List any included adapters or plugs on your product page for installer clarity.
