Pressure Relief Valve The PRV95 Pressure Relief Valve offers high performance with no impact with an ultrasoft opening and closing design.

• PRV95 is still in the prototype stage.
• This non-impact, no-oscillation relief valve solves current fluid system pressure problems associated with conventional "pop-type" relief valves.
• The PRV95 establishes Marotta in the pressure relief valve market.
• Marotta has invested $250,000 into the continued development of the PRV95.

• Marotta owns U.S. Patent No. 5,078,177 on the PRV95 Pressure Relief Valve.
• The primary target market for the valve is the aerospace industry, applicable to both ground support and flight applications.
• Marotta plans to take the concept and develop it for use with other line media, such as cryogenic service, liquids (water, diesel fuel, etc.) and natural gas.
• The unique competitive advantage of the PRV95 is its no-impact design.
• The valve utilizes a concept known as upstream control for valve positioning, making the valve more stable and exhibiting excellent repeatability and minimal hysteresis.
• The PRV95 is especially desirable when used in oxygen-rich environments where the possibility of an explosion or fire is very high with conventional pop-type relief valves.

• Applications within the aerospace industry include, but are not limited to, launch facilities, launch vehicles and test facilities
• Modified versions of the PRV95 will also be applicable for United States Navy and United States Army applications.
