SVL70 | Stainless Safety Relief Valve 10450 PSI Extreme Duty

SVL70 Stainless Safety Relief Valve 10450 PSI Extreme Duty

• The AR SVL70 Safety Relief Valve is a premium-grade stainless-steel overpressure protection
  component designed for extreme high-pressure hydraulic and water systems.
• Rated at 10,450 PSI, it automatically relieves excess pressure to protect pumps, hoses,
  fittings, and hydraulic components from catastrophic damage caused by pressure spikes or system malfunctions.
• Manufactured by Annovi Reverberi, the SVL70 combines Italian engineering, precise calibration,
  and long-term reliability for heavy-duty industrial, marine, and process applications.

Engineering & Construction

• Material: Solid, corrosion-resistant stainless steel body for maximum strength and durability.
• Pressure Rating: Factory calibrated for relief at 10,450 PSI, withstanding continuous exposure
  to extreme operating pressures.
• Internal Assembly: Precision-machined stainless-steel piston and high-tensile spring deliver
  smooth, instantaneous response to pressure changes.
• Sealing Elements: Specialized elastomer seals resist wear, heat, and chemical attack, maintaining
  leak-free performance across thousands of relief cycles.
• Thermal Management: Stainless-steel body acts as a heat sink, dissipating heat generated during
  relief events to preserve spring tension and seal integrity.

Functional Advantages

• Automatic Overpressure Relief: Opens the moment system pressure exceeds its 10,450 PSI setting,
  then reseats automatically once normal pressure is restored.
• Self-Actuating Reseal: No manual reset required, reducing downtime and eliminating the need for
  system bleeding or adjustment after activation.
• Consistent Performance: Precision calibration and durable seals ensure repeatable activation
  pressure and smooth operation, even under frequent pressure fluctuations.
• Redundant Safety: Functions as a critical secondary safeguard alongside unloaders and regulators,
  providing layered protection for high-value equipment.

Installation & Maintenance

• Compact Inline Design: Fits easily into pump manifolds, high-pressure frames, and hydraulic
  power units, ideal for both new builds and retrofits.
• Precision Threads: Machined threads provide a secure, leak-free connection and allow quick
  removal for inspection or service.
• Easy Service: Routine visual inspection, seat cleaning, and light lubrication are typically
  all that’s required for long-term, peak performance.

Typical Applications

• Industrial pressure washers and high-pressure cleaning rigs.
• Hydraulic test benches and proof-testing systems.
• Marine and offshore cleaning systems exposed to corrosive environments.
• Manufacturing and process lines operating at extreme pressures.
• Food, chemical, and process plants where stainless construction is required.
