The National Fire Protection Association (NFPA) provides regulations to protect your manufacturing plant from fires, deflagrations, explosions, and other safety risks.
NFPA compliance is a complex, ongoing effort. But the potential cost to your plant and your operations — not to mention your employees’ health and safety — means it’s worth examining from every angle.

MAP SEALâ„¢
All MAP Sealsâ„¢ 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 Sealâ„¢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.
