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.
