The National Fire Protection Association (NFPA) provides regulations to protect your manufacturing plant from fires, deflagrations, explosions, and other safety risks.

MAP SEAL™

All MAP Seals™ should be purged. Air that is 3 - 5  pounds of above line pressure is recommended. Air purging the seal creates a higher pressure inside the seal cavity which creates an air barrier that helps keep material inside the valve. With a MAP Seal™l and air purge, you can forget about those costly nitrogen purge systems and those messy grease purges you have to manually purge over and over again, yuck. Contact us for more information on our Proprietary MAP Seal™ System and start saving your valves, your product, and your bottom line today!
