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

• Accomplishments
• 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.

• Commercialization
• Marotta ownes 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.

• Government/Science Applications
• 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.
