SVL22/450 | Safety Relief Valve 2900 PSI Compact High Pressure

SVL22/450 | Safety Relief Valve 2900 PSI Compact High Pressure

• The AR SVL22/450 Safety Relief Valve is a precision-engineered pressure control device
  designed to protect high-pressure pump systems from dangerous overpressure conditions.
• Rated at 2,900 PSI, it automatically vents excess pressure to safeguard pumps, hoses,
  fittings, and hydraulic components from overload, failure, or damage caused by sudden pressure spikes.
• Manufactured by Annovi Reverberi, it is built for commercial and industrial systems that
  demand long-term safety, reliability, and consistent performance.

Key Specifications

• Model: SVL22/450 Safety Relief Valve
• Pressure Rating: 2,900 PSI (maximum relief setting)
• Function: Automatic overpressure relief and system protection
• Body Material: Corrosion-resistant brass
• Internal Components: Stainless-steel spring and piston assembly
• Sealing Elements: High-performance elastomer seals for high temperature and chemical resistance
• Typical Media: High-pressure water, detergents, and compatible process fluids
• Use Case: Secondary safety device used alongside primary regulators/unloaders

How the SVL22/450 Works

• Under normal operating pressure, a precision-calibrated stainless-steel spring keeps the valve
  closed, allowing full system pressure and flow to pass through the primary circuit.
• When system pressure rises above the 2,900 PSI set point, the internal piston overcomes spring
  tension and the valve opens to discharge excess fluid.
• This rapid venting instantly relieves pressure buildup, preventing damage to pumps, hoses,
  fittings, and connected components.
• As soon as pressure returns to the safe operating range, the spring reseats the piston automatically, restoring
  leak-free, normal operation without manual reset.
• A smooth internal flow path minimizes turbulence and water hammer, helping maintain stable hydraulic behavior
  during relief events.

Construction & Materials

• Brass body: Resists rust, scaling, and chemical degradation from high-pressure water and
  detergents while providing excellent mechanical strength.
• Stainless-steel spring and piston: Deliver precise, repeatable response to pressure changes and
  long-term resistance to fatigue and corrosion.
• Advanced elastomer seals: Formulated to withstand high temperatures, repeated pressure cycles,
  and chemical exposure while maintaining elasticity and sealing integrity.
• Compact, efficient profile: Minimizes flow restriction yet maintains full relief capacity to
  vent excess pressure quickly when required.
• Heat-dissipating brass housing: Effectively sheds heat generated during rapid venting cycles,
  protecting internal components from thermal stress.

Benefits & Performance Advantages

• Enhanced system safety: Provides automatic overpressure protection, reducing the risk of hose
  bursts, component failures, and catastrophic system damage.
• Redundant protection: Acts as a secondary safety device alongside the main regulator or
  unloader, engaging automatically if the primary control fails or becomes obstructed.
• Automatic resealing: Spring-powered reseat delivers leak-free operation after venting, avoiding
  downtime and eliminating the need for manual reset.
• Long service life: Rugged materials and high-quality seals support thousands of relief cycles
  with consistent performance.
• Stable hydraulics: Balanced design and smooth flow interior help prevent water hammer, pressure
  oscillations, and performance instability.
• Cost savings: Reduces equipment wear, unplanned failures, and repair costs related to
  overpressure events.

Installation & Service

• Easy integration: Precision-threaded connections allow direct mounting into pump manifolds,
  unloader blocks, or hydraulic lines using standard ports.
• Leak-free fit: Machined threads ensure a tight, secure seal that resists vibration and pressure
  fluctuations in mobile or stationary systems.
• Minimal maintenance: Routine cleaning and periodic inspection of the spring, seat, and sealing
  surfaces are typically all that is required.
• Service-friendly design: Modular construction allows quick disassembly for inspection or seal
  replacement by field technicians or maintenance crews.
• Best practices: Incorporate the valve as a backup safety device downstream of the pump and
  primary regulator, and include it in scheduled safety and performance checks.

Typical Applications

• Commercial pressure washers: Protects mid-range industrial pumps used in mobile wash rigs and
  stationary cleaning systems.
• Industrial cleaning systems: Safeguards high-pressure circuits in factories, plants, and
  process facilities.
• Hydraulic power units: Provides backup overpressure protection in high-pressure hydraulic
  circuits and auxiliary systems.
• Process equipment: Used wherever precise, reliable pressure control is critical to system
  safety and uptime.
• Mobile and stationary rigs: Ideal for trailers, skids, and fixed installations used in
  industrial, municipal, and commercial washdown applications.

Quality & Factory Testing

• Each SVL22/450 valve is factory-tested by AR North America to verify crack pressure, leak
  tightness, spring performance, and resealing accuracy.
• Every unit is calibrated to open at the specified 2,900 PSI threshold and reseat cleanly once
  pressure returns to the safe operating range.
• Consistent, repeatable activation characteristics help maintain overall system efficiency and long-term
  reliability.
