VHP39-PS2 | 5650 PSI PS2 Switch High-Pressure Unloader Valve

VHP39-PS2 | 5650 PSI PS2 Switch High-Pressure Unloader Valve

• The Annovi Reverberi VHP39-PS2 is a premium unloader valve designed for
  extreme-duty cleaning systems operating up to 5,650 PSI (≈390 BAR).
• Combines the trusted VHP39 unloader body with an integrated
  PS2 pressure switch for dual hydraulic and electronic protection.
• Provides automatic bypass safety plus pressure monitoring or shutdown capability,
  delivering an advanced, redundant protection system for industrial and contractor rigs.
• Ideal for high-pressure equipment where uptime, operator safety, and regulatory
  compliance are critical.

Advanced Protection with PS2 Integration

• Built-in PS2 pressure switch continuously monitors system pressure
  during operation.
• Switch can be wired to system controllers, safety shutoffs, or alarms
  for real-time response to unsafe conditions.
• Enables automatic shutdown or alarm triggers in the event of overpressure or fault
  conditions.
• Especially valuable in automated wash bays, multi-user contractor rigs, and industrial
  facilities with strict safety requirements.
• Integrates mechanical and electrical safety, reducing risk of equipment damage and
  enhancing operator confidence.

Automatic Bypass Function

• Uses the proven VHP39 unloader bypass mechanism for hydraulic safety.
• When the spray trigger is released, water is immediately diverted into bypass mode.
• Prevents overpressure that could damage pumps, hoses, seals, and accessories.
• Reduces system strain, extending the service life of pumps, seals, and lines.
• Ensures stable performance during intermittent and continuous-duty operation.
• Bypass system and PS2 switch work together for a dual-layer safety approach.

Rugged Industrial Design

• Reinforced housing engineered for long-term durability in high-pressure environments.
• Precision-machined internals provide smooth, accurate pressure regulation and
  repeatable performance.
• High-capacity design handles constant cycling without significant performance
  degradation.
• Compact profile adapts easily to both mobile rigs and
  fixed industrial wash stations.
• Built for applications where downtime is not an option and equipment must perform
  day after day.

Benefits for Operators & Facilities

• Dual protection: mechanical bypass plus electronic pressure monitoring.
• Automatic shutdown capability helps prevent catastrophic failures and costly repairs.
• Protects pumps, hoses, and accessories from pressure-related wear and shock loads.
• Supports regulatory compliance where redundant safety systems are required.
• Compact footprint and standard-style connections simplify installation and integration.
• Enhances system longevity and reliability in demanding industrial environments.
